GENERAL DESCRIPTION
1.1 Special Features
• High-speed, high-quality plotting
A digital servo drive system and a 32-bit CPU combine to produce detailed plots with smooth curves at a
maximum plotting speed of 700 mm/s (in all directions) and a mechanical resolution of 0.005 mm.
• Various functions ensure clearly-defined plots
A wide variety of functions come standard to ensure clearly-defined plots, including the Auto Pen Cap
function which prevents pens at the pen station from drying up when not in use and a mechanical soft-landing
mechanism that extends the pen's lifetime while providing a quieter working environment. The plotting speed
and pen force most suitable for the pen type being used can be easily selected from the control panel.
• Upright installation possible
To conserve space, the plotter can be mounted on a pair of stands (provided as a standard accessory) for
installation at a 60˚ angle.
• Interface conditions are easily set
The interface mode (RS-232C serial or Centronics parallel or USB-compatible) is automatically selected
when the plotter is connected to a computer via the respective interface connector.
If the plotter is set to Auto RS-232C mode, you just need to send plot data from the computer; the RS-232C
settings are automatically selected so no bothersome settings are required.
• Interactive operation
Various functions can be set interactively by using the panel keys according to messages and prompts
appearing on the display.
• Vector sorting function
This function speeds up plotting by minimizing the distance the pen travels in raised status from the end point
of one line to the starting point of the next line.
• Pen sorting function
To speed up plotting by reducing the number of pen exchanges required, this function reorganizes the
sequence in which plotting is performed so that each color is completely plotted before selecting the next
pen.

6.7 Using the Test Modes
6.7.1 Self Test
Your plotter comes with a self-test mode, which enables the plotter to check its own functions, without
necessarily being connected to the computer.
A correctly drawn test pattern signifies that all of the functions of the plotter (excluding the interface functions)
have been tested and found normal. Be sure to run this self-test before connecting the plotter to the
computer.
Procedure
(1) Check that the POWER switch is off and that pens are mounted in the pen station.
(2) Turn on the POWER switch while holding down the LEFT ARROW POSITION key.
The plotter is initialized.
The prompts below are consecutively displayed.

6.7.2 Character Dump Mode
This mode allows experienced users to detect the cause of communication problems between the plotter
and the computer. In Character Dump mode, the plotter produces an exact printout of the codes it receives,
printing character data as ASCII codes and the non-character (control) data as two-digit hexadecimal values
(e.g., 0A: Line Feed, 0D: Carriage Return).
Procedure
(1) Mount a pen in the pen station’s Pen 1 position.
(2) Place a sheet of paper on the writing panel.
(3) Hold down the DOWN ARROW POSITION key while you turn on the plotter.

6.7.3 Debug Mode
This mode is used to locate programming errors in your application program.
When the plotter is in Debug Mode, its buffer size is reduced to permit easier detection of the section of the
program that is causing the plotting error.
Procedure

The prompt below is displayed
Ready
(5) The plotter is now in the Debug Mode.
(6) Run the target program at the computer for output to the plotter.
The message DEBUG MODE is displayed for a few seconds.
In this mode, the plotter’s buffer memory is reduced to the following sizes:
• In RS-232C mode
: 256 bytes
• In Centronics mode : 10 bytes
(7) To exit the Debug Mode, turn off the plotter and then turn it back on using only the POWER switch.
HINT:
When using the RS-232C interface, the timing of data transmission varies with the selected
handshake mode as follows.
• During hardwire handshaking:
The ER (DTR) signal line goes off when the available space in the buffer drops to 64 bytes.
It goes on when the available space in the buffer rises to 128 bytes of data.
• During Xon/Xoff handshaking:
Xoff status is entered when the available space in the buffer drops to 32 bytes.
Xon status is entered when the available space in the buffer rises to 128 bytes of data.
NOTE:
After the plotter is turned off, Debug mode is not resumed when only the ENTER key is
pressed.
The Debug mode cannot be used with the USB interface.

ERROR MESSAGES
8.1 Hardware Error
Displayed message
POSITION
XY ALARM
Cause
This message appears when, for some reason, the current pen position
is invalid. In this case, turn the plotter off and then back on again.
8.2 GP-GL Command Errors
In GP-GL command mode, the plotter displays the error messages below if an error occurs for which
masking of the corresponding Error bit in the STATUS byte has been disabled using the ˝ command.
Displayed message
Cause
A command error occurs if a hexadecimal code from 60H to 7EH is
E1.
COMM ERR

PARA OV
E5.
I/O ERR
processed as a command character. This message may also appear if
the RS-232C interface conditions are improperly set or if the program
being run at the computer was not written using GP-GL commands.
When a command specifying coordinate values is being processed, a
parameter overflow error occurs if a numeric parameter exceeds the
“Parameter Range”.
An input/output error occurs during the transfer of data via the interface.
With the RS-232C interface, this message indicates that the parity or
data length may be improperly set. Check your interface conditions once
more.
Cancelling an error status
You can cancel an error status using any of the methods below, thereby setting the status of the
corresponding Error bit to zero.
(1) Execute a READ STATUS WORD 1 or READ STATUS WORD 3 command.
(2) Press the ENTER key. (Effective only in case of a data format error.)
Note:
If a data format error has occurred, performing either Method (1) or (2) above while
execution of the next command is temporarily suspended enables that command to be
executed.
(3) Initialize the plotter.
(4) Execute the INTERFACE CLEAR command.
Note:
Method (3) or (4) clears all the data in the plotter’s buffer memory.
