2.0 Set-up and Configuration
2.1 Printer Set-up
The following steps should be performed when the Printer is initially set up. Step 7 (Self-Test) should
be performed any time the Printer's switch settings have been changed.
1. Check the operating environment and power
•
Ensure that the printer is placed on a firm, flat surface.
• Ensure that the work area conditions are within recommended environmental range,
Section 1.3)
2.
•
Ensure that the supply voltage is correct for the version of the printer (115V or 230V).
•
Ensure that power is supplied from a properly-grounded outlet.
(See
Determine the set-up requirements
•
Determine the communications set-up (Serial or Parallel).
This selection will depend on the host computer or terminal's requirements. Most host
devices will provide a Serial interface. If the host's Parallel interface is to be used, a Parallel
Interface Converter cable (Part # 899516) will be needed.
•
If Serial communication is chosen, complete the following steps:
1. Select the protocol (either RS-232c or RS-422);
2. Determine the type of cable needed, and;
3. Determine Baud Rate and Word Length.

2.2.2.1
RAM Modules
RAM Modules are available in both 256K and 512K capacity. Both size modules will add 256K of memory
space for storing soft font, graphics, and label format data storage. The 512K RAM module also provides an
additional 256K for the label format buffer, which increases the maximum label length from 8.25 in. to 20 in.
RAM memory is volatile, that is, it requires power in order to retain data. When the Printer is turned off, all
data stored in RAM will be lost.
2.2.2.2 FLASH Modules
The 256K FLASH module provides the same storage function as the 256K RAM module, with the added
advantage that the FLASH module is non-volatile, that is, data will be held until erased or overwritten, even
without power.
NOTE - When using the Internal Batch program, a 256K FLASH module is required.
2.2.2.3 FONT Modules
Six 512K FONT modules are available. They are listed, along with other module types, in Table 2-3.

3.0 Basic Operations
This section briefly reviews the basic operation of the Printer, including the use of the Control Panel
and buttons, loading label stock, installing ribbons and using the Printer’s self test function.
3.1
Front Panel Controls
Fig. 3-1. Control Buttons, LEDs and LCD.
3.1.1
• Pause
Push Button Controls
The Pause button allows a print job to be interrupted and then re-started. Pushing the
switch causes the Printer to (1) stop printing upon completion of the current label, (2) turn
on the Pause indicator, and (3) stop the label counter while holding the count balance. All
data is retained in memory.
Pressing Pause a second time will (1) turn off the Pause indicator, and (2) re-start the
Printer and cause it to continue with the current print job.
21
• Feed
Basic Operations
The Feed button allows the operator to control the feeding of labels through the
Printer. The button works in different ways, depending on whether the Printer is
currently On Line or on Pause.
When on Pause, pressing Feed will immediately feed one label.
When On Line, the Printer will first finish printing the current job, and then feed one
label.
• Stop/Cancel
3.1.2
Pushing the Stop/Cancel button cancels the current print job. If another print job has
been sent to the Printer, it will begin to print the next job. If there is no other job, the
Printer stops.
LED Status Lights
Located above the Control Buttons are LEDs that provide information on machine status. The LED’s
are labeled On Line/Pause, Ribbon/Media, and Power.
• On Line/Pause The LED is on when the Printer is Paused, and off when the Printer is On Line.
• Paper/Ribbon
• Power
3.1.3
This LED is normally off. It comes on only to indicate a fault in the Media or Ribbon
path.
This LED comes on when the Printer is powered up, and stays on as long as the
Printer is receiving power.
Other Controls
• Darkness
Adjusts the darkness or lightness of the print image.
• Transfer Switch
Sets the Printer for either Thermal Transfer or Direct Thermal media.
Must be in the ON position when printing with a ribbon installed.
22
Basic Operations
3.2 Media and Ribbons
The following section describes print modes, how to load the stock, the stock sizes that can be used,
and how to install and remove ribbons.
3.2.1 Print Modes
The Printer can use either of two printing methods, called Direct Thermal and Thermal Transfer.
Both methods use heat to produce the printed image - they differ in the way in which the heat is
applied.
In Thermal Transfer printing, the individual dot elements of the Printhead apply heat to a ribbon. The
“ink” on the ribbon is a specially formulated material that is literally melted into the print media,
bonding with it to produce the black dots that form an image.
Direct Thermal printing dispenses with a ribbon and instead applies heat directly to the print media.
This media is formulated to react to the heat by turning black. Direct Thermal printing requires the use
of a special Direct Thermal print media. It also requires that if a ribbon is already installed it must be
removed.
NOTE - When Printing with the Thermal Transfer method, the Transfer Switch must be set to ON (See
Figure 3-1 for Transfer Switch Location). For Direct Thermal, the switch must be set to OFF.
NOTE - Using Direct Thermal print media while a ribbon is installed will produce unacceptably poor
print quality.
23
3.2.2
Basic Operations
Media
The Printer is designed to make loading media and ribbons a simple task. The following section
describes in detail how to load stock and ribbons.
3.2.2.1

Basic Operations
Stock Errors
When the stock is correctly loaded, the Media Sensor will detect the leading edge of each label as it
passes through the Printer. If the Printer advances stock more than 12 in. (305 mm.) without detecting
a label edge, an error condition will be triggered - the Printer will stop and the PAPER OUT light
will go ON. If this happens, first, be sure that the stock is routed as shown in Fig. 3-2. If the stock is
routed correct, adjust the Media Sensor by turning the Edge Sensor Adjust Knob (See Fig. 1-6)
clockwise one half-turn at a time until the error condition clears. If the adjustment fails to correct the
problem, refer to Section 4, "Troubleshooting".
If the stock feeds only a short distance and does not seem to stop on a label edge when the FEED
button is pressed, the THERMAL TRANSFER switch may be set to the ON position without a
ribbon installed. For Direct Thermal printing (no ribbon), the Transfer switch must in the OFF
position.
3.2.2.3
Stock Sizes
The Printer accepts a wide range of media sizes. It can be loaded with Roll Fed media of either
Thermal Transfer or Direct Thermal type. The table below lists the range of acceptable sizes

3.2.2.4
Basic Operations
Ribbon Installation
When using thermal transfer stock, a ribbon must be installed and the Thermal Transfer switch (Fig.
3-1) must be turned ON.
To Load Ribbon (See Fig. 3-2)
¶ Raise the Head Lift Lever clockwise to the UP position.
· Slide the ribbon roll onto the Supply Hub.
¸ Route the ribbon as shown in Fig. 3-2.
¹ Place the ribbon over the hub and slide the Ribbon Clasp onto the hub and ribbon.
º Wrap a few turns of ribbon (counter-clockwise) around the hub.
» Turn the Head Lift Lever counter-clockwise to the DOWN position.
Note: It may be necessary to feed a few labels before the ribbon aligns itself correctly.
To Remove Ribbon
Ribbon may be removed completely from the Printer, if desired. However, the procedure in Sec.
3.2.2.5 is also acceptable, and is generally more convenient.
To completely remove the ribbon:
¶ Raise the Head Lift Lever clockwise to the UP position.
· Remove the Ribbon Clasp, and unwind the end of the ribbon from the Supply Hub.
¸ Carefully pull the free end of the Ribbon back through the media path.
¹ Slide the ribbon roll off of the Supply Hub.
º Turn the Head Lift Lever counter-clockwise to the DOWN position
26
3.2.2.5
Basic Operations
Ribbon Removal - Alternate Method
When switching between Thermal Transfer and Direct Thermal media for different printing jobs, it is
not necessary to remove the ribbon completely. The ribbon may be removed from the Media Path,
without removing it from the Printer completely, in the following manner:
¶ Cut or tear the ribbon at a point near the Ribbon Take-up Hub.
· Turn the Head Lift Lever clockwise, to the UP position. It is not necessary to remove the
unused portion of the ribbon. Turn the Ribbon Shaft Supply Hub clockwise to draw the
unused portion of the ribbon back until it is clear of the Printhead.
¸ Turn the Ribbon Shaft Take-up Hub counter-clockwise to roll up the used portion of the
ribbon
¹ Remove the Ribbon Clasp, slide the used ribbon off the Hub and dispose of it.
º Turn the Head Lift Lever counter-clockwise to the DOWN position to lock the Printhead
The unused portion of the ribbon may be left in place until the next Thermal Transfer print job, at
which time it may be re-installed following the ribbon installation procedure
3.2.2.6
Self Test
Once the label stock (and ribbon, in thermal transfer mode) have been loaded, the next step is to
perform a Self Test. See Sec. 4, "Troubleshooting", for instructions on the Self Test.
NOTE - When performing the Self Test, for best results use labels 2.5 in. x 4.25 in. (64 x 108 mm.) or
larger.

Basic Operations
Using Printer Options
3.3.1
Memory Modules
The Printer uses external memory modules to expand its own 48K RAM internal memory space. The
internal RAM is called Memory bank A. The external module is called Memory Bank B.
Memory modules are used for storing; (1) graphic images, (2) bitmaps of smooth fonts, (3) label
formats for recall by host computers, and (4) Internal Batch program formats.
Memory modules are inserted into the slot located on the upper left side of the Printer (See Figure 3-3).
Place the module cartridge with the label facing the front of the printer, and slide the cartridge into the
slot until it seats itself.
Fig. 3-3. Memory Module Installation

3.3.2
Basic Operations
Memory Module Types
There are three types of External Memory Module, ROM, RAM, and FLASH.
3.3.2.1 Font ROM
The Printer has a built-in set of fonts. Additional font styles are available, stored on Font ROM
modules. The modules are programmed at the factory and cannot be used for any other purpose. The
documentation included with each module explains the font style, size range, and the font number for
each size.
3.3.2.2
256K and 512K SRAM Modules
When creating labels, label size is directly related to memory space. Creating larger or longer labels
uses more memory. SRAM modules are a simple way of plugging in more memory, making it possible
to print longer labels. Modules are available in two versions, 256K and 512K. The 256K SRAM
module provides storage space that can be used for fonts, graphic images or label formats. Like the
256K version, the 512K SRAM module sets aside 256K for data storage space. The remaining 256K
is used by the printer to extend its bit-mapped label area from 8.25 in. (210mm) to 20.25 in. (514mm).
When a module is added, the Printer recognizes the module as (external) Memory Bank B and uses it in
addition to its own 48K of built-in memory (Bank A). Data can be stored in the popular HP PCL-4
format (used by the HP LaserJet printer), as well as .PCX, .IMG, and .BMP formats.
RAM modules cannot be selectively erased. In order to remove a part of the data, the entire module
must be erased and the desired data re-loaded. In addition, RAM is "volatile", that is, it requires power
to operate. Turning the printer off, or removing the module, causes immediate loss of the data. (Note some popular Bar Code label programs require the use of volatile RAM).
3.3.2.3
256K FLASH Module
FLASH modules provide the same features as RAM modules, with the added benefit of virtually
permanent storage. Unlike the RAM module, FLASH memory does not require power in order to
retain data. In addition, the module contains a WRITE PROTECT switch to prevent data stored on
the cartridge from being overwritten or erased.

3.3.3 Cutter Description
This option consists of a Cutter mechanism and a tray. The Cutter mechanism shears off labels from
continuous rolls, under the control of the Printer. The cut labels are collected in the tray. The Printer
may be ordered with the option factory installed, or it may be ordered and installed later by the user.
When ordered separately, the option comes with complete installation instructions.
CAUTION: If attaching or removing the Cutter option, turn the printer OFF for 2 minutes or longer
before proceeding.

Basic Operations
3.4 General Maintenance
3.4.1
Cleaning the Printer - Interior and Exterior
• Interior
During normal operation, dust, dirt and debris from label stock can build up inside the Printer.
Clean any debris away regularly using a soft bristle brush or a vacuum cleaner.
• Exterior
The exterior surfaces may be cleaned as needed, using a general purpose cleaner and a damp (not
wet) soft cloth or sponge. Do not use abrasive cleansers or solvents.
3.4.2 Cleaning the Printhead
Occasionally foreign particles may collect on the Printhead. This can cause characters or bar codes to appear
light or faded, or, labels may show spots, spaces, or a continuous light streak in the same physical position on
each printed line.
NOTE: This condition will be encountered more often if poor quality paper has been used. To minimize the
chance of this happening, always use good quality stock. Your local printer supplier can provide a
list of approved stock types.
3.4.2.1 Recommended cleaning intervals:
The Printhead must be cleaned as needed. If spots, streaks, or drop-outs appear on printed labels, the first
step in improving print quality should be to clean the Printhead.
In Thermal Transfer printing, the ribbon will help to keep the Printhead clean, so, remember that if Direct
Thermal is the main printing mode in use, the Printhead will require cleaning more often.
Two cleaning methods are outlined below. The quick cleaning method is convenient, since it does not require
that the Printhead be removed. However, this method may not remove heavy buildups of debris. In these cases,
the Thorough Cleaning method should be used.

NOTE - For very bad soiling, acetone may be used to remove severe contamination build-ups.
3.6 Lubrication
All bearings in the Printer are either permanently lubricated or made of materials that do not require
lubrication. The Slip Clutches are pre-lubricated, and therefore, under normal circumstances they need no
lubrication. However, if the Ribbon Supply Slip Clutch begins to squeak or hum, it may be lubricated as
follows:
3.6.1 Ribbon Supply Clutch Lubrication
To lubricate:
¶ Remove the Printer cover to expose the electronics compartment. (Sec. 6.1)
· Using needle-nosed pliers, or a similar tool, unhook one end of the Clutch Spring from the Shaft Support
Bracket (Fig. 3-7).

Troubleshooting
Overview
This chapter discusses a number of topics related to troubleshooting the Printer. It covers the
generation and use of the pre-programmed Configuration and Test Labels, the Printer's Power On Self
Test, Error Messages and their causes, and some techniques for isolating and correcting faults.
When faults are isolated to the Main Logic or Operator’s Panel P.C. boards, it is recommended that the
entire P.C. board be replaced. Only insertion and removal instructions for socketed components, (i.e;
RAM, EPROM, etc.) and jumper settings are provided in this manual. It is not generally feasible to
provide component level service in the field.
4.1 About the Self Test
To begin the Self-Test:
¶ If the Printer is ON, turn the power OFF.
· Press the FEED button, and, while holding the button down, turn the power ON.
The printer will power up in the Self Test mode. It will feed one blank label and then print two Test
Labels. The first label is the Configuration Test Label, which contains a listing of the Printer's
current set-up and status. The second label is the Dot Pattern Test Label, which is an array of printed
dots that is very useful when testing for possible Printhead faults.
4.1.1 Character Dump Mode
When the self test is complete, the printer shifts to the Character Dump mode. In its normal mode,
some of the data sent to the Printer would represent the characters to be printed, while other data would
be format commands and other control codes. In Character Dump mode, the Printer will print the
numerical data sent from the host as though they were all ASCII characters. This mode is useful
when testing serial transmissions from the host device to the printer.
39
Troubleshooting
4.1.2 Testing with Continuous Media
Continuous media presents a special problem when performing the Self -Test. Each time the Printer is
turned on, all set-up options revert to the default settings. One of the settings that is changed is the
Label Edge Sensor. If the label stock in use is of the Continuous type, the Label Edge Sensor will not
detect any label edges, which will trigger an error condition.
To avoid this problem, a special software command was written which starts the Self-Test without
allowing the Printer to re-set the defaults. The command STX Z will print the Self Test information
and STX P will change to Character Dump Mode.
A sample program which will send these software commands is listed in the Appendix. Complete
information on sending software commands may be found in the Programmer's Manual for Allegro,
Prodigy, and Prodigy Plus (Part No. 88-2054-01).
4.1.3
Loopback Plug Tests
The operation of the Serial Ports (RS-232c or RS-422) can be checked by plugging a Loopback Test
Plug into the Serial Port and performing the TXD/RXD and CTS/RTS loop check tests. The Loop
Checks will automatically be performed as a part of the Self-Test, so long as the Test Plug has been
plugged in before the tests are started.
If a Test Plug is not available, one can be made by following the connection pattern shown in Appendix
Sec. A-1.
If the Loopback Tests were successful, the test results will be printed on lines 7 and 8 of the Test
Label.
If the tests are not successful, lines 7 and 8 of the Test Label will be blank.
If the Printer passes one test and fails the other, the result of the successful test will be printed in the
appropriate line.

SYSTEM ROM CHECKSUM: A882 IS GOOD
Checksum is a method used to test the validity of data stored in the printer's ROM memory. The
test result should be GOOD. If the data in the ROM has been damaged, the checksum will say
BAD, indicating that the system EPROM has been corrupted and should be replaced.
5.
SYSTEM RAM CHECKS GOOD
RAM memory is tested in a way similar to the ROM checksum. The test result must say GOOD. A
defect with the printer’s internal RAM will cause the test result to say BAD, indicating a problem
on the Main Logic Board, usually with the installed RAM.
6.
SERIAL PORT BAUD RATE IS 9600
The baud rate (Serial data transmission rate) is selectable, using the DIP switches located on the
back of the printer. The default rate is 9600 baud. The actual current setting is printed on the Test
Label.
7.
SERIAL LOOP BACK CHECK IS GOOD
This is the result of the test of the Printer's TX and RX communication line. This is the only line
needed for the XON/XOFF communications protocol.
8.
CTS & DTR LOOP BACK CHECK IS GOOD
This is the result of the test of the Printer's hardware handshaking signals. These lines must operate
properly for hardware handshaking to work.
NOTE - Lines 7 and 8 will be printed only if the Test Plug is installed and the Serial
communications are operating correctly. If the test plug is installed and this line still
does not appear on the test label, a hardware problem with the printer’s
communications system should be suspected.

PAPER: 229 EDGE: 173 VOLT: 195
16. TEMP: 062 POT : 133
LINES 14 - 16 of the Test Label are values which correspond to the voltages that were detected in the
Analog to Digital converter circuits on the Printer's Main Logic Board. The voltages will normally vary
slightly from printer to printer and from label to label. The information is usually most useful during
in-shop technical support, but may also be useful when troubleshooting in the field.
Values may range from 0 to 255, where 000 = 0.0 V, 1.00 = 19.6 mV, and 255 = 5.0 V.
PAPER: 229
EDGE: 173
The PAPER and EDGE values are voltages measured in the Media Edge and Reflective Sensors.
Potentiometer RP2 controls this value. The PAPER value represents the voltage detected when paper is
present in the sensor. The EDGE value represents the voltage detected when only media backing is
present at the sensor. The PAPER value should always be larger than the EDGE, usually about 120%
greater.
43
Troubleshooting
TEMP: 062
The TEMP value is the voltage detected at the Printhead Thermistor. During power up or idle at
room temperature, this value should be between 060 and 065. Normal printing will produce readings
ranging from 070 to 120. Consistent readings above 130 indicate voltages that could decrease the life
of the Printhead.
POT: 133
POT is the voltage setting of the Darkness Potentiometer on the front panel board. It will vary from
000 (darkest) to 255 (lightest). Generally, this value should be set to a midrange of 128.
VOLT: 195
VOLT is a voltage reading is meant expressly for engineering and production use at the factory. It
should be somewhere near 190.

4.1.6 Self-Test Dot Pattern Label
The second label printed is the Dot Pattern Label. This is an element and electronic matrix test which
checks all of the Printhead’s electronic circuitry. If there is a hardware problem, such as a burned out
Printhead element, the defect will show up on the test label (shown below). This label will print the
entire width of the Printhead. If there are areas of missing print, including streaks or spots, refer to Sec.
4.4.3, Troubleshooting, "Problem Isolation Checklist - Print Quality".
Fig. 4-2.
Dot Test Label
4.1.7
Using the Character Dump Mode
Once the Dot Pattern Test Label has been printed, the Printer will set itself to Character Dump Mode.
This means that all data sent from the host device will be printed as a continuous string of data. Any
numeric value that equals an ASCII character will be printed as that character (Any ASCII values less
than 20 are interpreted as control characters).
The Printer will begin to print the data in its buffer as soon as a full line of information has been
received from the host, or whenever the data stream from the host has been paused for more than 0.25
second.
45
Troubleshooting
4.1.8 Using a Character Dump Label
Character Dump mode is used mainly to detect problems in the data flow from the host to the Printer.
The simplest way to check the data flow is to repeatedly send label data (such as the example shown in
Fig. 4-3) to the Printer. The test will uncover such errors as data corrupted by a defective cable, Serial
Port malfunctions, or overflow of the Printer's buffer (which is characterized by large gaps in the
printed text). A sample Test Label program is included in Appendix Section A2.1.

Troubleshooting
4.2 Improving Printer Performance
4.2.1
Decreasing Processing Time and Increasing Throughput:
An important question with any machine is, how quickly and efficiently can it perform it's task? Before
looking at ways to decrease the Printer's processing time and increase the speed of its throughput, it
may help to understand what happens during the Printer's processing phase.
The label formatting process requires time to read the label field data and to move it into the Printer's
bit-mapped buffers. Before the Printer can begin to print the label it must process and map 203 Kbytes
of data. This can take from virtually no time at all to several seconds, depending on the complexity of
the label format and the size of the area that will be printed on.
When the processing and mapping process is complete, the printer will begin to print as many labels as
were requested by the software's Quantity command. Generally there is no delay between the printing
of each label. However, the following situations will tend to add time between each label.
•
Printing different data on each label. A batch of different labels are being sent to the printer in
a continuous string of data. The Printer must process and map between each label.
•
Placing an incrementing field in the label format. An Incrementing field is one in which the
value of the field changes by a set amount between each label. These fields are embedded in the
label format and will continue to change the label format until the end of the batch has been
reached.
•
Including a time and date field in the label format. If the time and date are to be printed on the
label, the field must be updated for every label printed in the batch.
•
Using external module fonts. Time is added because the Printer must refer to the external
module in addition to the normal processing time.
•
Printing in rotations other than 1. Rotation adds a step to the normal processing cycle.
•
Using the Cutter option. The printer must stop and wait for the cutter to execute the cutting
cycle.
47
Troubleshooting
4.2.2 Preventing Data Loss:
Data loss and other communication problems can have many sources. This section presents some ideas
on ways to isolate these problems and determine their cause.
The Printer is a Serial ASCII device, that is, the host system must be able to interface to other
equipment in ASCII format, using a serial communication I/O port. The Printer uses both hardware
and software handshaking and sends both forms of handshaking simultaneously whenever the printer's
input buffer is full. Handshaking is the practice of using a standard set of control signals, either
software codes or signals sent by wire, to reduce the occurrence of lost data. Loss of data will cause
printing errors.
The Printer's hardware handshaking is the logic state on pin 20 of connector J4, the RS-232/422
communications port located at the back of the printer (See Figure 1-4 for location). This signal will be
High when the printer is ready to receive data. The signal will be Low when the Printer's input buffer
is full. In this state, the printer is busy and can no longer receive data.
The Printer uses the software handshaking standard called XON/XOFF. In this system, when the
Printer's input buffer is full, an XOFF (CHR$19) character is sent, which tells the host system that
the printer is full and cannot receive any more data. When the input buffer has memory space
available, the printer will send an XON (CHR$17) character. This tells the host device that the printer
is ready to receive more data.
If the printer seems to have communication problems, check the following first:
¶
Verify that the correct interface cable is installed between the host device and the Printer.
The wrong kind of cable will make it impossible for the Printer to communicate correctly.
·
Verify that the DIP Switch positions (Switch S1, located on the back of the printer) are set
correctly for the current application.
Printing the Configuration Test Labels, using the Character Dump Mode, and performing the
Loopback Tests will help identify the type of printer set-up errors that can generate
problems.
48
Troubleshooting
4.3 Printer Cabling and Interfacing
When the printer receives data from any host system, it will not function properly with an incorrectly
wired cable. Proper wiring diagrams can be found in the Appendix. Table 4-2, below, lists the signal

Adjustments
5.1 Introduction
This chapter discusses the adjustments that might sometimes be necessary to keep the Printer at
maximum performance. Most often, adjustments are needed when the label stock being used varies
significantly from the standard size of 4 in. width and 4 mil thickness. There are also adjustments that
should be made when major components, such as the Printhead, have been replaced.
5.2 Controlling Print Quality
In order to offer the greatest flexibility, the Printer operates in both Direct Thermal and Thermal
Transfer modes. However, due to the differences in these two technologies, some "fine tuning" may be
required to maintain the highest print quality. These adjustments are discussed below.
The two most important factors that determine print quality are the amount of heat applied to the
Printhead, and the position of the Printhead relative to the label media.
Applied Heat
The heat that must be generated by the Printhead depends on the Reaction Temperature of the Print
Media or Thermal Transfer Ribbon. The reaction temperature is the amount of heat needed to turn the
media black, or to transfer an image from the ribbon. Many low cost types of direct thermal stock have
very high reaction temperatures - it takes a great deal of heat to make clear images on this type of
paper. On the other hand, Thermal Transfer Ribbons have a relatively low Reaction Temperature. The
Printer has limits placed in the range of possible heat adjustments, in order to prevent settings that
could damage the Printhead. The applied heat may be controlled either by adjusting the Darkness
potentiometer, or by increasing the burn time through software. (For more information on adjusting
burn time with software, see the Programmer's Manual for Allegro, Prodigy and Prodigy Plus,
"Label Format Commands".)
Printhead Position
The Printer has been factory set to produce good print quality with most media. However, when using
stock other than the recommended 4 mil thickness, the Printhead position, ribbon, and media
tracking may all require slight adjustments in order to maintain highest quality.
61
Adjustments
5.3 When Adjustments are Needed
Adjustments must be considered when dealing with any of the following situations:
• Narrow Stock
When using stock narrower than the standard 4 in. width, an adjustment may be needed to prevent the
Printhead from rubbing on the Drive Roller.
• Tag Stock and Stiff Media
When stock that is thicker than 4 mil is in use, the Printhead can be moved forward,
providing a slightly larger gap and allowing the thicker media to move freely along the
path.
media
• Direct Thermal Stock
Direct Thermal media generally requires greater heat than Thermal Transfer media in order to produce a
comparable image. The print "burn point" can be moved closer to the Drive Roller, where the heat is
greater.
• Printhead Mounting Assembly
The Printhead mounting system is designed so that there is normally no need to align a newly installed
Printhead. However, if the Head Mount Assembly has been removed (for example, when replacing the
Drive Roller), this adjustment should be performed.
• Electrical Adjustments
It is normal for the Printer's Edge Sensors to occasionally need small electrical adjustment to keep the
sensor's sensitivity in the correct range. It may also sometimes be necessary to confirm the Power
Supply voltage levels or ground.
NOTE - Unless otherwise stated, all adjustments should be performed with label stock that is at least 4 in.
(102mm) wide. If the media that will normally be used is of a different size, make the standard
adjustments first (using 4 in. media), and then fine tune the adjustments using the stock size that
will be actually used.
62
Adjustments
5.4 Adjusting for Narrow Stock
This adjustment should be performed when the stock to be used is narrower than 3.5 in. (89 mm). The
parts involved in the adjustments are shown in Fig. 5-1 and 5-2.
Fig. 5-1. Printhead Mount Assembly
The Head Support Plate, shown in the figure above, is designed to support the outer end of the
Printhead when narrow stock is in use. Engaging the Support Plate ensures that the Printhead does not
contact the Drive Roller, which would potentially damage the Printhead and prematurely wear out the
Drive Roller.
63
Adjustments
To Adjust for Narrow Stock:
¶ Loosen the two screws that attach the Head Support Plate and Ribbon Shield to
the Printhead Mount frame. Leave the left side screw slightly snugged.
· Load a supply of 4 in. wide label stock. (See Sec. 3.2.2.1 for stock loading
instructions). Turn the Head Lift Lever to the DOWN position to engage the Printhead.
¸ Push down the right side of the Head Support Plate until the Plate just contacts the Bearing Block
Mounting Bracket
¹ Turn the Head Support Adjustment Screw until it just contacts the Bearing Block Mounting
Bracket.
º
Tighten the two screws to secure the Head Support Plate and Ribbon Shield.
NOTE - The same screws secure both the Head Support Plate and Ribbon Shield, so that moving one
could cause the other to move. Be aware, and avoid this if possible.
64
Adjustments
5.5 Adjusting for Stiff or Tag Stock
The horizontal position of the Printhead is set by turning the right and left Head Adjustment Screws,
which move the corresponding side of the Printhead in or out. When using stock that is much thicker
than 4 mil, adjusting the Printhead away from the Roller may improve print quality. Note - This is a
sensitive adjustment - A small turn can make a large difference in the print quality. Adjust these screws
no more than 1/4 turn at a time until the print is satisfactory.
CAUTION:
Do not turn the head adjusting screws more than 2 complete turns in either direction.
Damage to the head mount assembly will result if the adjustment screws are turned too far.
5.6 Adjusting for Direct Thermal Stock
When the Printhead is set-up for use with thermal transfer stock, the Printhead burn point is set at a
position on the roller where the ribbon separates from the label while the wax ink is still hot enough to
be in a liquid state.
When direct thermal stock is used, the Printhead burn point should be moved slightly back, to a point
where there is greater contact with the roller, causing heat to transfer to the media more efficiently.
For best results when using direct thermal label stock, turn both of the two Head Adjust screws 1/4
turn clockwise. Figure 5-2 is a partial cut-away view from the right side of the Printer, showing the
Adjustment Screw Location. This adjustment will move the Printhead 0.006 in. (0.15mm) back on the
roller. Remember to adjust back to the original position when returning to Thermal Transfer media.
65
Adjustments
5.7 Adjusting for Printhead Alignment
The Printhead is precisely positioned on mount plate locating pins that are set at the factory. The
locating pins should ensure correct alignment of all future replacement heads - it should not normally
be necessary to re-align each new Printhead. However, if the Printhead mount assembly has been
removed or disassembled, and there has been a consequent loss of print quality, the following
alignment procedure may be required. Performing all steps, in the order given, should eliminate any
problems with print quality.
Figures 5-1 and 5-2 illustrate the portions of the Printhead mounting assembly that are involved in the
adjustment procedures.
There are four adjustments required to align the Printhead. They are:

Adjustments
Stock Tracking Adjustment
For proper performance, it is critical that the stock move evenly through the media path. Any skewing
will affect the print quality, and in some cases can cause jamming. The Stock Tracking Adjustment
must be done with the printer power ON and a full roll of 4" (102mm) stock installed.
¶
Load the stock in the normal way, but keep the Media Retainer in the DOWN position.
·
Use the FEED button to feed a few labels. At first the edge of the stock may move in and out as
the media advances. After a few labels the stock should begin to track at a stable position.
¸
At this point, slightly bend the Media Guide Plate up or down to adjust the tracking position to
within approximately 0.3 in. (8 mm.) of the center plate. Bending the Plate down will move the
tracking position closer to the Center Plate, while bending up will move the tracking position
farther from the Center Plate.
(NOTE - It is suggested that a small object, such as a pen or pencil, should be placed between the
Guide Plates. This will prevent bending the Plates so close together that the media will no longer
feed smoothly.)
¹
Rotate the Media Edge Guide to the UP position, and stop feeding labels.
67
Adjustments
5.7.2 Ribbon Feed and Tracking Adjustment
This adjustment must be performed with the printer power ON, a full roll of 4" (102mm) stock, and a
ribbon installed. (See Chapter 3, Fig 3-2 for Ribbon Loading instructions). Complete the steps for
installing the ribbon, except, do not secure the ribbon to the Ribbon Take-Up Hub.
¶ Press the FEED button several times and check to see if any wrinkling or bagging of the ribbon
occurs as it moves from the supply hub and goes under the Printhead assembly. If rippling or
bagging does occur, go to step 2. If no wrinkling is observed, go on to the Printhead Fine
Adjustment procedure, Section 5.7.3.
· The next step is to adjust the tension and position of the Ribbon Supply Hub. Maintaining an
even tension will help eliminate ribbon wrinkling. On the Shaft Support Bracket, slightly loosen
(but do not remove) the four screws securing the bracket to the Center Plate (Fig. 5-3).
¸ Apply moderate pressure up or down on the Ribbon Supply Hub or the Shaft Support Bracket
while pressing FEED to advance labels. The object is to reposition the Supply Hub so that
ribbon tension is even across entire width of the media path. An even tension should eliminate
any ribbon wrinkling.

68
Adjustments
¹ Once the bracket is positioned properly, re-tighten the four screws that attach the bracket to the
Center Plate. Feed three or four more labels to re-check the ribbon. Make certain that the ribbon
does not ripple or bag.
º Feed ribbon and labels together from the front of the printer. Check the ribbon to be sure that the
ribbon and label edges stay aligned. If the ribbon overlaps one edge of the paper stock, the ribbon
and paper are not following the same path. Should this happen, the Ribbon Shield position may
need to be adjusted. If the ribbon shows no overlap, proceed to the Printhead Fine Adjustment
procedure, Section 5.7.3.
» To adjust the Ribbon Shield, gently push the ribbon out of the way and loosen (but do not
remove) the screw securing the left side of the Head Support Plate and Ribbon Shield (Fig. 5-4).
¼ Press the FEED button to advance labels, while moving the left side of the Ribbon Shield up or
down until the edges of labels and ribbon track together.

¶
Print a few labels with Bar Codes rotated at either 90° or 270°, and inspect the print quality.
Imperfections in the print will be more evident in the rotated Bar Code images. If the print
quality is less than satisfactory, go to step 2.
Rotated Bar Codes are available on the Ribbon Test Label. To produce this label:
• Simultaneously press the PAUSE and FEED buttons. The Printer will generate a label
with a Bar Code in normal rotation.
• Press the STOP/CANCEL button.
• Press the PAUSE button. The Printer will generate a label with Bar Codes in 90°
rotation.
·
With a 1/16" (1.59mm) hex key, turn the left and right Head Adjustment Screws (Fig. 5-2)
either clockwise or counter-clockwise 1/4 to 1/2 turn at a time, until the desired print quality is
achieved.
Never turn these screws more than 1/2 turn at a time or more than 2 full turns in total.
¸
Adjusting the head position often moves the Bearing Block out of contact with the Head Support
Plate. Loosen the two screws that secure the Bearing Block Mounting Bracket. Push the Bearing
Block back until it just contacts the Head Support Plate.
¹
Tighten the two mounting screws to secure the Bearing Block and Mounting Plate.
º
Sometimes performing the Printhead Fine Adjustment can slightly change the stock and ribbon
tracking settings. Feed a few labels and look for any return of ribbon wrinkling. If there is any
sign of ribbon tracking problems, return to Section 5.7.2 Ribbon Feed and Tracking
Adjustment, and repeat the adjustment.
70
Adjustments
5.7.4 Printhead Pressure and Support Adjustment
The function of the Head Support Plate is to support the outer end of the Printhead when narrower
media is being used. Without this support, the Printhead would press on the drive roller, causing poor
print quality, premature wear and possible Printhead damage. The head support plate is needed only
when the media width is less than 3.5".
Pressure for the Printhead is provided by two springs in the head mount assembly. These springs apply
a constant force on the Printhead. If media that is less than 3.5 in. (89 mm.) wide is to be used, the
Printhead Support Plate should be adjusted. Figure 5-4 shows the assembled Printhead Mount. Figure
5-1 illustrates the relevant parts of the Printhead Mount in an exploded view.
To adjust:
¶ Loosen the two screws securing the Head Support Plate to the Printhead Mount. Leave the screw on
the left side slightly snug (Fig. 5-4)
· Load a supply of the media to be used. Turn the Head Lift Lever to the DOWN position to engage
the Printhead.
¸ Turning the Head Support Adjustment Screw will raise and lower the right side of the Printhead.
Turn the Adjustment Screw clockwise until the print on the right side of the label begins to degrade.
¹ Turn the Adjustment Screw back 1/4 turn counter-clockwise to set the correct adjustment.
º Finally, tighten the two mounting screws to secure the Head Support Plate.

5.8 Sensor Adjustments
The Printer contains a pair of sensors in the media path which merit discussion. Both the Label Edge
Sensor and the Reflective Edge Sensor are designed to operate without adjustment. However, if
components in either sensor's circuit have been replaced, the sensor may need a set-up adjustment.
Procedures for adjusting both sensors are given below.
5.8.1
Label Edge Sensor Adjustment
¶ Remove the Printer's outer cover to expose the Main Logic Board (Sec. 6.1).
· Remove a few labels from their backing, and locate the Media Sensor (Fig. 5-5).

¹ Connect a Multi-meter to the Main Logic Board - the black lead connects
heat sink, and red lead to Test Point TP1
to the
º Adjust potentiometer RP2 until the meter shows a reading of between 0.15 and 0.35 volts DC.
» Press the FEED button. The Printer may feed a few labels while it aligns
itself.
Afterwards, it will feed one label each time the Feed button is
pressed. When a
label is in place in the sensor, the voltage at TP1 should be greater than 2.0 volts DC.
¼ Replace the Printer's cover.

Adjustments
5.8.2 Reflective Edge Sensor Adjustment
The Reflective Edge Sensor detects the motion and position of label stock by sensing the presence of a
"carbon black" line on the back side of the label. Since the sensor operates by detecting interruptions in
a beam of infra-red light, this line must be a non-reflecting flat black that will absorb the infra-red
beam.
This adjustment should be performed with power on, 4 in. width label stock loaded, and the Printer
connected to a host terminal. The labels used in the procedure must be reflective type, with a black
line on the back.
¶ Remove the Printer's cover to expose the Main Logic Board (Sec. 6.1).
· Remove a few labels from their backing, and locate the sensor.
¸ Place some of the label backing material between the "fingers" of the sensor

¹ Connect a Multimeter to the Main Logic Board. Connect the black lead
(Common) to the heat sink, and red lead (Positive) to Test Point TP1 (Fig. 5-6).
º Set the Printer to Reflective Sensor mode. (Note - Changing the sensing mode requires that the
Printer be connected to a host unit. Sending the command string "<CTL> B r" from the host unit
switches the Printer to Reflective sensing mode. (A sample program to send this command string
may be found in Appendix Sec. A2.0). See the Programmer's Manual for Allegro, Prodigy, and
Prodigy Plus (Part No. 88-2054-01) for further information on using command strings.
» Adjust potentiometer RP1 until the meter reads 0.75 Volts DC.
¼ Press the FEED button. The Printer may feed a few labels while it self-aligns. It will then feed
one label each time the button is pressed. When the reflective black mark is in place within the
sensor, the voltage at TP1 should be greater than 2.0 volts DC.
½ Replace the Printer's cover.

5.9 Electrical Checks
Three electrical tests may occasionally be needed, since incorrect voltage levels or bad grounds can
generate many problems in the Printer. These are tests of the ground, the 5 Volt and the 24 Volt supply
voltages, which are discussed below. If the ground or the voltage levels are not within the required
tolerances, refer to Section 4, Troubleshooting, and follow the procedures listed.
5.9.1
Ground Test
¶
Connect a Voltmeter to the Printer in the following way: Connect the Common lead (black) to
the heat sink located at the base of the Main Logic Board. Set the meter to measure the range
around 10mV. Connect the Positive lead (red) to the left side lead of capacitor C45, located
near the top of the Main Logic Board.
·
The voltage measured should be less than 10mV. If the voltage reading is above 10mV, or if
it shows large fluctuations, re-connect the Common lead to the heat sink and then re-measure.
If the voltage is still wrong, check the components connected to the heat sink - one of them
may be defective.

Circuit Description
7.0 Circuit Description
7.1 General Overview
The Printer uses a single board design, in which functions to control the receipt of data and generation of dot
patterns for the printing process, as well as the Printer's internal housekeeping and control, all reside on one
Main Board. The Printer uses extensive software processing, rather than relying on hardware, to convert
ASCII string commands into the dot patterns that will be printed.
Because of this, typical troubleshooting techniques for hardware-based systems do not apply well to this
product. For some components, such as keypad I/O, RS-232/422 I/O, motor function, and switch input,
replacing socketed components could be economical. However, in most other cases it is more efficient and
economical to replace the complete Main Board.
Several other smaller boards and devices attach to the Main Board. These boards, such as the Front Panel,
Options Interfacing and Sensor LED boards, primarily contain discrete component circuitry. A wiring
diagram is included with the Schematic Drawings at the back of this manual. It shows the Main Board and its
relationship to all of the connecting devices.
This section explains the function and operation of these boards. The information will provide assistance when
it is necessary to connect other devices to the Printer, or to repair a unit that has been damaged.
7.2 Input Power Circuitry
Input power is connected through connector CJ1, located at the rear of the printer. The CJ1 circuit uses a
CORCOM filter to filter out common line noise. However, it will not protect the printer from all types of EMI
or RFI noise. Its main purpose is to keep the Printer from passing noise back down the line to other devices.
Power is applied through the Power-On switch. This is a SPST (Single Pole Single Throw) switch for the
115V model, and DPST (Double Pole Single Throw) for the 230V model.
The printer has one Line Transformer which is fuse linked both internally and externally. The external fuse for
the 115V model is a 1.0 Amp slow blow fuse. The 230V model requires two .5 Amp slow blow fuses. The
Transformer has a single primary, so, the wiring can not be changed in the field - the printer must be
ordered with the desired voltage configuration factory installed.
P/N: 510391
108
Circuit Description
7.3 Main Logic Board
The Main Logic Board contains the power supplies, CPU, memory, Serial I/O, front panel and motor I/O
logic, as well as the logic that supplies data to the Printhead. The following is an explanation of the function of
the most important components on the Main Logic Board. Details of the board may be found in the Schematic
Diagram section at the end of this manual.
Quick board repairs may sometimes be made simply by swapping out socketed components. However, it is not
recommended that the board be repaired to any further degree. When problems are detected with the Main
Logic Board, the best approach is to replace the entire board!
U4 & U8
RS-232C and RS-422 line drivers. If these chips are damaged by high voltage spikes or
misuse, they may be replaced. The outputs of these two components connect to other
circuitry in such a way that they are enabled by connecting wires to the pins on connector
J4.
U3 & U9
System RAM. It is also checked when the Self-Test is run. A RAM error statement on the
Configuration Label can usually be corrected by replacing the indicated chip.
U10
74HC245 IC. Buffers the settings of the DIP switch (SW1, on the back of the Printer)
from the Main Board's data bus. If the Configuration Label, printed by the self-test,
indicates that the switch values do not change after the DIP switch has been physically
changed, this componant may be defective. The DIP switch bank may also be changed, if
necessary.
U13
System ROM. It is checked during power up and any other time the Self-Test is run. A
ROM error statement on the Configuration Label can usually be corrected by replacing
the indicated chip.
U22-U24, U27
Refresh and Bank Select. These components control the refresh cycles and bank select
of the dynamic RAM.
P/N: 510391
109
Circuit Description
U2 & U6
Act as Buffers between the Main Board and the Front Panel Board and Sensors.
This I/O device can sometimes be damaged by unusually strong static electrical
discharges. Since this component acts to buffer TTL level data, if there is no LED
or push-button response from the front panel, replacing the chip may correct the
problem.
U14, U21, U25, U27
Printhead Control Circuit. These components are the IC's that most directly
affect the burning of dots by the Printhead. These components are seldom
damaged, but if replacing them is considered, replace the complete set of four.
U5, U14, U16,
U17, U24, U27
Memory Module Control Circuit. These are the IC's which control
the operation of all the memory modules. U16 supplies the voltage used to
program Flash modules. U17 buffers the addressing of the Memory Modules. The
other IC's primarily control the selection of modules, or the function being
performed.
7.4 Front Panel Board
The Front Panel Board controls the front panel switches, transfer switch, LED's and the Darkness
pot. This board connects to the Main Board through a single ribbon cable.
7.5 Label Sensor Assembly
This board is mounted to the Sensor Shaft, just below the Printhead. The assembly includes two small
brackets which guide the media through the sensor. The Sensor itself consists of paired LED's and
optical receivers. Inputs from these components pass directly to the Main Board through the J5
connector. The Main Board both samples and buffers these inputs as part of the printing control
process.
The Label Sensor can operate in either an Edge or a Reflective sensing mode. The Main Board
controls which type of sensing operation is used.
P/N: 510391
110
Circuit Description
7.6 Ribbon Sensor Assembly
The Printer uses a "movement present" type sensor, in contrast to the more common "see-through"
type. This sensor scheme detects the rotation of a reflective label attached to the inside of the Ribbon
Supply Hub. When the sensor fails to detect Hub motion, the Printer triggers a RIBBON OUT
condition. The RIBBON/TRANSFER switch, located on the front of the printer, disables the Ribbon
Sensor completely when Direct Thermal label stock is in use.
7.7 Printhead
The Printhead connects to the Main Board through connector J7. Most Printhead functions require +24
Volts DC. The Printhead itself is a thin-film type head, with both latch and forward type logic, to help
decrease the delay time between the printing of each row of dots.
7.8 Stepper Motor
The Stepper Motor is a 6 Volt DC motor capable of generating about double the torque required to pull
six inch rolls of media and a matching ribbon through the printer. If Stepper Motor related problems
occur, the first item to check for is a stock jam in the Printer.
The Stepper Motor is connected to the Main Board through connector J9. Component U20 (which is
not easily replaced) contains the drive transistors for the stepper motor. In most cases, replacing the
entire Main Board and/or Stepper Motor is the most efficient way to service the unit.
7.9
Memory Module
The Printer contains two memory banks. Bank A refers to the Printer's built-in RAM. Bank B refers to
the external Memory Module. There are four different Memory Modules that can be used by the
Printer; Font, 256K Flash, 256K RAM, and 512K RAM. The memory modules may be tested by
running the Printer using "PC-Batch" labeling software or an equivalent program, using the Memory
Module Maintenance (ALT-S) screen or it's equivalent. It may also be tested by running the Printer's
built in Self-Test, and checking the Configuration Label RAM Test results.
P/N: 510391
111
7.9.1
Circuit Description
256K Flash EPROM Module
This type of module is based on the 256K Flash EPROM, which is similar to the standard EPROM
except that it can be erased electronically. Flash EPROMs have the advantages of RAM data storage,
with the added feature of not requiring power to retain data. The only significant disadvantage with
the Flash module is that it is somewhat slower than RAM when reading or writing data.
Flash modules may be used to store any combination of graphic images, charters fonts, or label
formats. This type of module features a write protect switch, to prevent important data from being
accidentally overwritten. The module can be programmed when the write protection is off (the write
protect switch on the module is moved towards the center of the module). The Flash module is rated to
be re-programmed 10,000 times without failure.
7.9.2 256K and 512K RAM Module
The 256K and 512K RAM Modules may be used for the same type of data storage as the Flash
Module. However, since RAM memory is volatile, when the Printer is turned OFF, all data will be
immediately lost. Both 256K and 512K RAM Modules provide an additional 256K of memory for
storing soft fonts, graphics, and label format data. The additional 256K of storage space in the 512K
RAM module can be used to increase the label format buffer from its normal limit of 8.25 inches to as
much as 20 inches.
7.9.3 Font Modules
The Font Modules contain pre-programmed data which is permanently stored. Font Modules cannot
be written to or erased. It is, however, sometimes possible for Font Module data to be corrupted.
To test a Font Module for corrupt data;
¶ Load the Font Module into the Printer's Module slot;
· Turn the printer OFF.
¸ Press and hold the front panel FEED button, and, while holding, turn the printer ON. The Printer
should print a Test Label which will contain the Font Module checksum and will state whether the
module is GOOD or BAD.

Serial to Parallel Adapter
A1.3.1
Adapter Description
The Parallel to Serial Interface Adapter is designed specifically for use with the Printer. It is a one-way
communications, self-powered device, and therefore, no external power source is required. Although
the adapter resembles a standard interface cable, it actually has sophisticated microprocessor circuitry
built into the head assembly. This circuit converts standard parallel data to the RS-232 serial
communication standard. This adapter is used when connecting with a PC that has only a parallel port
available.
A1.3.2
Installing the Parallel to Serial Adapter
¶ Turn the Printer OFF.
· Connect the cable according to the label on each plug - the side labeled PC must plug into the PC's
parallel printer port, and the side labeled PRINTER must plug the Printer's RS-232 serial port.
¸ The Printer must be set to default communication settings. These are: 9600 baud,
8 data bits, 1 stop bit, no parity. (The default settings are selected by setting DIP Switch SW1,
positions 1, 2, 3, and 4 to OFF).
¹ Turn the Printer ON.
CAUTION -
P/N: 510391
Always TURN POWER OFF BEFORE connecting the Parallel to Serial
Interface Adapter.

A2.0 Sample Programs
The following sample programs are intended to aid the technician in testing and performing
adjustments. They provide a useful test label and some software switching functions.
These programs are created in the DOS environment, using the EDIT command. Additional
information on DOS and EDIT can be found using the DOS HELP function, or the DOS manual.
•
All of the sample programs require the use of the ^B character. Creating the ^B character in DOS is
done in the following way:
¶ At the DOS prompt, simultaneously press the CTRL key and the "P" key.
· Simultaneously press the CTRL key and the "B" key.
•
When entering command sequences (e.g.; ^BZ) there should be no space between the ^B character and
any following characters (^BZ, not ^B Z).
•
If the host unit's COM port has not been set, it may be necessary to run the DOS MODE command. To
do so:
¶ At the DOS prompt, type MODE COM1:9600,N,8,1
· Press ENTER.

A2.2 Beginning the Self Test Without a Printer Reset
As noted in the text, testing the Printer with Continuous media installed presents a special problem,
since the Test sequence begins with a reset, which changes the Printer to its default settings. After a
reset, the Label Edge Sensor will be active, but will fail to detect label edges on the Continuous media.
The following program will avoid this problem by beginning the Self Test or the Character Dump mode
without allowing the Printer to reset.
To create the file:
EDIT TEST.LAB
· Press ENTER. DOS's EDIT program will start.
¸ Type
^Bc0100
^BZ (for Self Test) or ^BP (for Character Dump Mode)
¹ From the EDIT menu at the top of the screen, choose SAVE and EXIT.
To send the file:
COPY TEST.LAB COM1:
» Press ENTER. The Printer should now begin the chosen function.

A2.3 Setting the Printer to Reflective Mode
The Printer can only be set to Reflective Sensing Mode through the use of a software command. The
following program will switch the Printer from Transmissive to Reflective Mode.
To create the file:
EDIT TEST.REF
· Press Enter. DOS's EDIT program will start.
¸ Type
^Br
¹ From the EDIT menu at the top of the screen, choose SAVE and EXIT.
To send the file:
COPY TEST. REF COM1:
» Press ENTER. The Reflective Sensor should now be active.
