1 INTRODUCTION
1.1.
SAFETY PRECAUTIONS
1. Before servicing, unplug the AC power cord to prevent an electric shock.
2. When replacing parts, use only the manufacturer´s recommended components.
3. Check the condition of the power cord. Replace if wear or damage is evident.
4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure to perform the following insulation resistance test to prevent
the customer from being exposed to shock hazards.
1.2.
INSULATION RESISTANCE TEST
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part
(screw heads, control shafts, bottom frame, etc.).
Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.
4. If the measurement is outside the specified limits, there is a possibility of a shock hazard.
1.3.
FOR SERVICE TECHNICIANS
ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help prevent recurring malfunctions.
1. Cover the plastic part´s boxes with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on the worktable.
4. Do not touch the IC or LSI pins with bare fingers.
1.4.
BATTERY CAUTION
CAUTION
Danger of explosion if the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to following caution:
Disposal of lithium batteries should be performed by permitted, professional disposal firms knowledgeable in state government
federal and local hazardous materials and hazardous waste transportation and disposal requirements.
A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in strong
packaging.
Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their ultimate
disposition. This is a good practice for all types of commercial or industrial waste.
Recommend Type Number:
CR2032 (BAT501) Manufactured by MATSUSHITA

TROUBLESHOOTING DETAILS
OUTLINE
Troubleshooting is for recovering quality and reliability by determining the broken component and replacing, adjusting or cleaning
it as required. First, determine the problem then decide the troubleshooting method. If you have difficulty finding the broken part,
determine which board is broken. (For example: the Digital PCB, Analog PCB, etc.) The claim tag from a customer or dealer may
use different expressions for the same problem, as they are not a technician or engineer. Using your experience, test the problem
area corresponding to the claim. Also, returns from a customer or dealer often have a claim tag. For these cases as well, you need
to determine the problem. Test the unit using the simple check list on 2.3.3.1 SIMPLE CHECK LIST(P.38). Difficult problems may
be hard to determine, so repeated testing is necessary.

Remarks:
Regarding the reception problem, we have investigated the conceivable causes in the flow chart except for the software-related
errors. However, some troubles may occur due to the software-related problems such as "OUT OF PAPER" when the fax
switches to the memory receiving mode and the memory capacity becomes full of the unprintable data. In this case, error
messages [MEMORY FULL] and its main cause, for example "CHECK PAPER" are displayed on the LCD. Once you solve the
main problem, [MEMORY FULL] will be cancelled and the reception problem will be resolved.

THE UNIT CAN COPY, BUT CANNOT TRANSMIT/RECEIVE
CROSS REFERENCE:
2.3.5.1.5.
THE UNIT CAN COPY, BUT CANNOT EITHER TRANSMIT/RECEIVE LONG
DISTANCE OR INTERNATIONL COMMUNICATIONS
The following two causes can be considered for this symptom.
Cause 1:
The other party is executing automatic dialing, the call has been received by this unit, and the CED or DIS signal response time
is too long. (In most cases, this unit detects the CNG signal and can respond to CED or DIS.) (According to the ITU-T standard,
the communication procedure is cancelled when there is no response from the other party within 35 sec, so that the other party
releases the line.)
56
KX-FPC91
(Cause and Countermeasure)
As shown in the chart above, the total handshaking time must be reduced, but because of the long distance connection and
linking of several stations, the line connection time cannot be reduced. Accordingly, the following countermeasures should be
tried.
(A)... As the 35 sec. count is started directly after dialing or directly after the START button has been pressed for models with
a START button, the other party should be called manually, if possible. Another possibility is entering two pauses at the end of
the auto dial number on the transmission side. Then the count start time can be delayed for 2 pauses (about 10 sec.).
Cause 2:
Erroneous detection because of an echo or an echo canceler.
(Echo/Echo Canceler)
The signal from FAX1 reaches FAX2 via stations 1 and 2, but the reflection signal at station 2 also returns via station 1 (echo).
As the distance between station 1 and station 2 is far, the echo returns to FAX 1 at a max of 600 msec after transmission. There
is a possibility that this signal is detected erroneously as the signal from FAX2. For a normal call, there is also a possibility that
the echo of their own voice will make the call difficult to understand. For this reason, each station (station 1 and station 2)
attaches echo cancelers (S1 and S2) for international lines or long distance lines. For the echo canceler, the level of the
transmission signal from FAX 1 is compared with the level of the reception signal from FAX2. When the transmission signal is
larger, S1 is closed while S2 is opened when it is smaller. In other words, for transmission from FAX1, S1 is closed and S2 is
open, so that the echo does not return to FAX1.
(Causes and Countermeasures)
(Cause A)
When a training signal is transmitted from FAX1 during the communication procedure at the time of transmission from FAX1 to
FAX2, there is a delay until the echo canceler operates. S1 is closed so that a part of the head of the training signal may drop
out. Normal reception by FAX2 may not be possible, and transmission may not be started.
(Countermeasure A)
When the international line mode is ON in the service mode (code No. 521), a dummy signal is attached to the head of the
training signal to prevent this problem. As this is normally ON, it is necessary to reconfirm that this has not become OFF. When
the international mode is switched OFF, the transmission side will try the training signal three times at each speed (9600BPS,
4800BPS and 2400BPS). If NG, it will drop the speed by one rank (fall-back). When the international mode is switched ON,
each speed will be tried only twice. In other words, the slower speed with fewer errors can be accessed more easily. This is
done because the line conditions may deteriorate and the picture may be disturbed more easily during communication for
international lines or long distance communication, even when the training is OK. The default value is ON as preference is given
to clearer pictures rather than speed.
(Cause B)
The echo canceler operation stops with a 2100Hz signal. (i.e. S1 and S2 become ON). Accordingly, when FAX1 has executed
automatic reception, a CED signal is output. If this signal is 2100Hz, S1 and S2 will become ON. Then the echo of the DIS
signal output afterwards may be received and FAX1 may execute an erroneous operation, preventing communication from
starting.
(Countermeasure B)
In the service mode, the CED signal frequency is set to 1100 Hz (code No.520), or the time setting between the CED signal and
the DIS signal is set from 75 msec to 500 msec in the service mode (code No.593). This is because the echo canceler operation
stop mode is canceled by an interval of 250 msec or more.
Reduce receiving sensitivity to reduce the effect of RCV echo signal. (Service mode: code No. 598)
57
KX-FPC91
(Cause C)
This model is FAX1 and the other party is FAX2.
For transmission from this model to FAX2, FAX2 executes automatic reception and transmits a CED signal (2100 Hz) followed
by a DIS signal. As the echo cancelers stops as described in cause B, the echo of the DIS signal returns to FAX2. On the other
hand, this model detects the DIS signal and transmits a DCS signal. In other words, it is possible that the echo of the DIS signal
and the DCS signal transmitted from this model reach FAX2 one after the other. FAX2 detects an error and communication
does not start.
(Countermeasure C)
When the international DIS detection setting is set in the service mode (code No.594), this model does not respond to the first
DIS signal and returns a DCS signal only for the second DIS signal.
In other words, there is an interval of 250 msec between transmission of the first and second DIS signal so that the echo
cancelers operation recovers. An echo is not generated for the second DIS signal.
Note:
When the other FAX does not respond with a DCS signal after DIS signal transmission, the DIS signal is transmitted three times
for trial.
Summary:
Symptom/Countermeasure Table (Long distance and international communication operations)
SYMPTOM
Does not receive in the automatic mode.
COUNTERMEASURE
1. If possible, manual transmission should be done from the transmission side.

REMOTE PROGRAMMING
If, after the call is connected, the customer describes the situation and it is determined that the problem can be corrected by
making parameter changes, this function makes it possible to change parameters such as the user code and service code from
another fax (using DTMF tones). Therefore, travel to the customer´s location is not required. However, it is not possible to
change all the parameters remotely (2.3.5.2.2 PROGRAM MODE TABLE(P.69)). The function used to accomplish this is
remote programming.
First, in order to check the current status of the service code parameter, print out the setup list (code: 991) and the service list
(code: 999) from the customer´s fax machine.
Based on this, the parameters for the desired codes can be changed.
The procedure for changing and listing parameters is described on 2.3.5.2.1 ENTERING THE REMOTE PROGRAMMING
MODE AND CHANGING SERVICE CODES(P.68). Also, before exiting the remote programming mode, it is advisable to obtain
a new list to confirm that the changes were made correctly.
Hint:
Since the connected telephone is in use during the remote programming mode, it may be helpful to ask the customer to switch
to the speakerphone. This frees the customer from the need to remain right next to the fax while you are making parameter
settings. When finished, inform the customer. Also note that in very noisy locations where the DTMF tones are not audible, the
remote programming function will not work.

DIGITAL BOARD SECTION
When the unit fails to boot up the system, take the troubleshooting procedures very carefully. It may have a serious problem.
The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.)
The first step is to check the power source. If there is no problem with the power supply unit, the problem may lie in the digital
unit (main board).
As there are many potential causes in this case (ASIC, DRAM, etc.), it may be difficult to specify what you should check first.
If a mistake is made in the order of checks, a normal part may be determined faulty, wasting both time and money.
Although the tendency is to regard the problem as a serious one (IC malfunction, etc.), usually most cases are caused by solder
faults (poor contact due to a tunnel in the solder, signal short circuit due to solder waste).
Note:
1. Electrical continuity may have existed at the factory check, but a faulty contact occurred as a result of vibration, etc., during
transport.
2. Solder waste remaining on the board may get caught under the IC during transport, causing a short circuit.
Before we begin mass production, several hundred trial units are produced at the plant, various tests are applied and any
malfunctions are analyzed. (In past experiences, digital IC (especially SRAM, DRAM and ROM) malfunctions are extremely rare
after installation in the product.)
This may be repaired by replacing the IC, (DRAM etc.). However, the real cause may not have been an IC malfunction but a
soldering fault instead.
Soldering faults difficult to detect with the naked eye are common, particularly for ASIC and RA (Resistor Array). But if you have
an oscilloscope, you can easily determine the problem site or IC malfunction by checking the main signal lines.
Even if you don’t have such a measuring instrument, by checking each main signal line and resoldering it, in many cases the
problem will be resolved.
An explanation of the main signals (for booting up the unit) is presented below.
What are the main signals for booting up the unit?
Please refer to 2.3.6.1 DIGITAL BLOCK DIAGRAM (P.72).
The ASIC (IC501) controls all the other digital ICs. When the power is turned on, the ASIC retrieves the operation code stored
in the ROM (IC502), then follows the instructions for controlling each IC. All ICs have some inner registers that are assigned to
a certain address.
It is the address bus by which the ASIC designates the location inside each IC. And the data bus reads or writes the data in
order to transmit the instructions from the ASIC to the ICs.
These signal lines are all controlled by voltages of 5V (H) or 0V (L).
71
KX-FPC91
2.3.6.1.
DIGITAL BLOCK DIAGRAM
You also need to check the signal lines listed here [List 1] when the unit fails to boot up the system. Those signal lines should
remain normal. Other signal lines are not directly related to that failure even if they have faults or troubles.
As long as these signals remain normal, once the power is turned on, each IC can repeatedly output 5V (H) and 0V (L). The
following shows NG and normal wave patterns.
72
KX-FPC91
NG Wave pattern (Refer to NG EXAMPLE)
73
KX-FPC91
Normal Wave Patterns
Remarks:
When you use an oscilloscope to judge whether a signal to be
tested is normal or NG, perform the signal check in exactly the
same order as in [List 1]. (If the ASIC fails to access the ROM,
the ASIC cannot access SRAM or DRAM normally.)
The digital circuit actually operates according to the timing combinations of these signals. If the timing of these signals is even
slightly delayed, the circuit will not work. Nor will it if the IC is defective and the output voltage level is not normal although the
timing of these signals is accurate enough to meet the specifications. (Make sure that your oscilloscope is calibrated before
starting a test.)
Therefore, it is imperative to confirm whether each IC outputs the signal at the correct level. (See the I/O Pin No. Diagram.)
The signal level should be constantly output at between 5V (H) and 0V (L) as described earlier.
Note:
Simply check the output level and make sure if the IC repeatedly outputs the signal at between 5V (H) and 0V (L).
74
KX-FPC91
I/O and Pin No. Diagram
75
KX-FPC91
After the power is turned on, the ASIC initializes and checks each IC.
The ROM, SRAM, and modem are checked.
If initialization fails for the ICs , the system will not boot up.
In this case, please find the cause as follows.

ANALOG BOARD SECTION
This chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending
upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone
line. The signal mainly flowing on this route is analog. You can trace the signal with an oscilloscope. The signal flow on each
route is shown in the Check Sheet here. If you find a specific problem in the unit, for example if you cannot communicate with
the H/S, trace that signal route locally with the following Check Sheet and locate the faulty point.

KEY COMPONENTS FOR TROUBLESHOOTING
Check the following parts first: F101, D101-D104, C106, Q101, PC101 and IC101.
This comes from our experience with experimental tests. For example: power supply and lightning surge voltage test, withstanding
voltage test, intentional short circuit test, etc.
Caution:
If you find a melted fuse in the unit, do not turn on the power until you locate and repair the faulty parts (except for the fuse);
otherwise the fuse will melt again and you cannot pinpoint the faulty point.
In most cases, the symptom is that nothing is output. It is more likely that the fault is in the primary side rather than the secondary
side. Check the primary side first.

(D101, D102, D103, D104)
Check for a short-circuit in terminal 4. If D101, D102, D103 and D104 are short-circuits, F101 will melt (open).
In this case, replace all of the parts (D101, D102, D103, D104, F101).
(Q101)
The worst case of Q101 is a short-circuit between the Drain and Gate because damage expands to the peripheral circuit of Q101.
This is due to a very high voltage through the Gate circuit which is composed of R128, R109, D106 and IC101.
You should change all of the parts listed as follows.
F101, Q101, R128, R109, D106, IC101
(D201)
If D201 is broken, the oscillation circuit in the power supply cannot operate. Check it with an electric tester.

5 HOW TO REPLACE THE FLAT PACKAGE IC
Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount),
a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.
5.1.
PREPARATION
· SOLDER
Sparkle Solder 115A-1, 115B-1 OR Almit Solder KR-19, KR-19RMA
· Soldering iron
Recommended power consumption is between 30 W to 40 W.
Temperature of Copper Rod 662 ± 50°F (350 ± 10°C)
(An expert may handle a 60~80 W iron, but a beginner might damage the foil by overheating.)
· Flux
HI115 Specific gravity 0.863
(Original flux should be replaced daily.)
5.2.
FLAT PACKAGE IC REMOVAL PROCEDURE
1. Put plenty of solder on the IC pins so that the pins can be completely covered.
Note:
If the IC pins are not soldered enough, you may give pressure to the P.C. board when cutting the pins with a cutter.
2. Make a few cuts into the joint (between the IC and its pins) first and then cut off the pins thoroughly.
3. While the solder melts, remove it together with the IC pins.
When you attach a new IC to the board, remove all solder left on the land with some tools like a soldering wire. If some solder is
left at the joint on the board, the new IC will not be attached properly.

RESET CIRCUIT (WATCH DOG TIMER)
The output signal from pin 1 of the voltage detect IC (IC507) is input to the ASIC (IC501) 136 pin. Then the output signal from pin
109 of the ASIC (IC501) resets the ASIC.
1. During a momentary power interruption, a positive reset pulse of 46~51 msec is generated and the system is reset completely.
2. When pin 132 and 133 of IC501 become low level, they will prohibit the SRAM (IC504) from changing data.
The SRAM (IC504) will go into the backup mode, when they are backed up by a lithium battery.
3. The watch dog timer, built-in the ASIC (IC501), is initialized by the CPU about every 1.5 ms.
When a watch dog error occurs, pin 137 of the ASIC (IC501) becomes low level.
The terminal of the ´WDERR´ signal is connected to the reset line, so the ´WDERR´ signal works as the reset signal.

SRAM AND RTC BACKUP CIRCUIT
1. Function
This unit has a lithium battery (BAT501) which works for the SRAM (IC504) and Real Time Clock IC (RTC: inside IC501).
The user parameters for autodial numbers, the system setup data and others are stored in the SRAM (IC504).
The RTC continues to work, backed up by a lithium battery even when the power switch is OFF.
2. SRAM (IC504) Backup Circuit Operation
When the power switch is turned ON, power is supplied through pin 12 of IC501 to the SRAM (IC504). At this time, the voltage
at pin 28 of the SRAM is 5V. When the power switch is turned OFF, the BAT501 supplies power to the SRAM through J501,
R543 and R508. The voltage at pin 28 of the SRAM is about +2.5V. When the power switch is OFF and the voltage of +5V
decreases, the voltage detect IC (IC507) outputs "Low" level and the IC501 outputs the reset signal. Pin 28 of the SRAM
becomes roughly the same voltage as the battery voltage. At this point, pin 20 (CS) of IC504 becomes high level, causing the
SRAM to go into the backup mode, in which the power consumption is lower.
3. RTC Inside (IC501) Backup Circuit Operation
When the power switch is turned ON, power is supplied through DA501 to the RTC (inside IC501). At this time, the voltage at
pin 7 of the IC501 is +3.3V. When the power switch is turned OFF, the BAT501 supplies power to RTC through DA501. The
voltage at pin 7 of IC501 is about +2.5V. When the power switch is OFF and the voltage of +3.3V decreases, pin 7 of RTC
(IC501) becomes roughly the same voltage as the battery voltage. RTC goes into the backup mode, in which the power
consumption is lower.

SUPERVISION CIRCUIT FOR THE THERMAL HEAD TEMPERATURE
1. Function
The thermistor changes the resistor according to the temperature and uses the thermistor´s characteristics. The output of pin
169 of IC501 becomes a low level. Then when it becomes a high level, it triggers point A In point C, according to the voltage
output time, the thermal head´s temperature is detected.
After the thermal head temperature is converted to voltage in B, it is then changed to digital data in the A/D converter inside
IC501. The CPU decides the strobe width of the thermal head according to this value. Therefore, this circuit can keep the
thermal head at an even temperature in order to stabilize the printing density and prevent the head from being overheated.

IMAGE DATA FLOW DURING FACSIMILE OPERATION
Copy (Fine, Super-Fine, Half Tone)
1. Line information is read by CIS (to be used as the reference white level) via route1, and is input to IC501. Refer to 6.4.2
BLOCK DIAGRAM(P.158)
2. In IC501, the data is adjusted to a suitable level for A/D conversion in the Analog Signal Processing Section, and via route2
it is input to A/D conversion (8 bit). After finishing A/D conversion, the data is input to the Image Processing Section via
route3. Then via route4 and route5, it is stored in RAM as shading data.
3. The draft’s information that is read by CIS is input to IC501 via route1. After it is adjusted to a suitable level for A/D
conversion via route2, the draft’s information is converted to A/D (8 bit), and it is input to the Image Processing Section. The
other side, the shading data which flows from RAM via route6 and route7, is input to the Image Processing Section. After
finishing the draft’s information image processing, white is regarded as "0" and black is regarded as "1". Then via routes4
and 5, they are stored in RAM.
4. The white/black data stored as above via routes6 and 8 is input to the P/S converter. The white/black data converted to
serial data in the P/S converter is input to the Thermal Head via route9 and is printed out on recording paper.

Transmission
1. Same processing as Copy items 1 - 3.
2. The data stored in the RAM of IC501 is output from IC501 via routes6 and 10, and is stored in the system bus.
Via route11, it is stored in the communication buffer inside DRAM (IC503).
3. While retrieving data stored in the communication buffer synchronous with the modem, the CPU (inside IC501) inputs the
data to the modem along route12, where it is converted to serial analog data and forwarded over the telephone lines via the
NCU Section.
Reception
1. The serial analog image data is received over the telephone lines and input to the modem via the NCU section, where it is
demodulated to parallel digital data. Then the CPU (IC501) stores the data in the communication buffer DRAM (IC503)
along route12.
2. The data stored in DRAM (IC503) is decoded by the CPU (IC501) via route12, and is stored in DRAM (IC503) via routes13
and 5.
3. Same processing as Copy item 4.

THERMAL HEAD
1. Function
This unit utilizes the state of the art thermal printer technology.
The ink film is chemically processed. The ink film is comprised of two parts: an ink layer and a base film. When the thermal head
contacts this ink film, it emits heat momentarily, and the ink layer is melted and transferred to the paper. If this continues, letters
and/or diagrams appear, and the original document is reproduced.
2. Circuit Operation
Refer to the block diagram and the timing chart on the following page.
There are 9 driver ICs aligned horizontally on the thermal head and each one of these ICs can drive 192 heat-emitting registers.
This means that one line is at a density of 192×9=1728 dots=(8 dots/mm).
White/Black (white=0, black=1) data in one line increment is synchronized at IC501 pin 150 (THCLK), and sent from IC501 pin
149 (THDAT) to the shift register of the ICs. The shift registers of the 9 ICs are connected in series, and upon the shift of the
1728 dot increment, the shift register becomes filled with data, and a latch pulse is emitted to each IC from IC501 pin 151
(THLAT).
With this latch pulse, all the contents of the shift registers are latched to the latch registers. Thereafter, through the addition of
strobes from the IC501 pins (142, 143), only the dot location of black (=1) among latched data activates the driver, and the
current passes to heat the emitting body to cause heat emission.
Here, the two line strobes, STB1 to STB2, impress at intervals of 9.216 msec, as required for one-line printout.
The sequence is shown on the next page. [Moreover, for the strobe width, the thermistor value inside the thermal head is
detected according to IC501 pin 2. Depending on that value, the strobe width is recorded in ROM (IC502). Accordingly, the
strobe width is determined.]
When the thermal head is not used, the IC501 (141, THON) becomes low , Q502 turns OFF, IC506 turns OFF, and the +24V
power supply for the thermal head driver is not impressed to protect the IC.

SCANNING BLOCK
The scanning block of this device consists of a control circuit and a contact image sensor made up of a celfoc lens array, an LED
array, and photoelectric conversion elements.
When an original document is inserted and the start button pressed, pin 20 of IC501 goes to a high level and the transistor Q512
turns on.This applies voltage to the LED array to light it. The contact image sensor is driven by each of the FTG-F1 signals output
from IC501, and the original image illuminated by the LED array undergoes photoelectric conversion to output an analog image
signal (SIG). The analog image signal is input to the system ASIC on AIN1 (pin 1 of IC501) and converted into 8-bit data by the A/D
converter inside IC501. Then this signal undergoes digital processing in order to obtain a high-quality image.

STEPPING MOTOR DRIVE CIRCUIT
1. Function
The stepping motor works for both transmission and reception.
2. Motor
During motor driving, pin 163 of ASIC IC501 becomes a high level, and Q503, Q501 turns ON. As a result, +24V is supplied
to the motor coil.
Stepping pulses are output from ASIC IC501 pins, 157, 160~162, causing driver IC508 pins, 13~16 to drive the Motor Coil. The
motor coil is energized sequentially in 2 phase increments, which causes a 1-step rotation. A 1-step rotation feeds 0.13 mm of
recording paper or document paper.

When the motor suspends while it is in the receive mode (about 70~80 msec), pin 163 of ASIC IC501 becomes a low level and
Q503 turns OFF. Then Q501 also turns OFF, and instead of +24 V, +5 V is supplied through D501 so that the motor is held in place.
When the system is in the stand-by mode, all of the motor drive transistors turn OFF. Consequently, the motor current stops.

GEAR SECTION
This model provides a motor-driven gear mechanism for transmitting/copying documents and printing fax data. In this chapter,
you will see how the gears work to select and operate a mode and how the gear section, sensors and rollers mechanically work
during the main operations (FAX transmission, FAX reception and Copy).
6.4.6.1.
MODE SELECTION (See Fig. 1)
When a motor with Drive Motor Gear attached rotates counterclockwise (CCW), Swing Gear C engages CAM Gear to rotate
counterclockwise (CCW). This operation provide four mode options (A: Transmit mode, B: Paper-Pickup mode, C: Receive mode
and D: Copy mode) selected by the Sensor Switch. (The Sensor Switch Lever’s position in the CAM Gear controlled by the software
selects a specific mode.) You can see which mode is selected by confirming the Mode Marker’s position as shown in
Fig. 1-a~1-d.
(Ex. If the Mode Marker is in position A, a transmit mode is selected.)
Note:
The arrows show the directions in which the active gears turn around.

MODE OPERATION
Once a mode is selected, the Drive Motor Gear rotates clockwise (CW) and then the controlling positions of Swing Gears A, B
and C determine which gears convey their drive power in each mode.
A. Transmit mode (See Fig. A.) :
Swing Gear A engages Gear E and conveys its power to the Separation Roller Gear through Gear G and sets the Separation
Roller for feeding documents.

MODEM SECTION
6.6.1.
FUNCTION
The unit uses a 1 chip modem (IC505) that serves as an interface between the control section for FAX transmission and
reception and the telephone line. During a transmitting operation, the digital image signals are modulated and sent to the
telephone line.
During a receiving operation, the analog image signals which are received via the telephone line are demodulated and
converted into digital image signals. The communication format and procedures for FAX communication are standardized by
ITU-T. This 1 chip modem (IC505) has hardware which sends and detects all of the necessary signals for FAX communication.
It can be controlled by writing commands from the CPU (IC501: inside ASIC) to the register in the modem (IC505).
This modem (IC505) also sends DTMF signals, generates a call tone (from the speaker), and detects a busy tone and dial
tones.
Overview of Facsimile Communication Procedures (ITU-T Recommendation):
1. ON CCITT (International Telegraph and Telephone Consultative Committee)
The No. XIV Group of ITU-T, one of the four permanent organizations of the International Telecommunications Union (ITU),
investigates and make recommendations on international standards for facsimiles.
2. Definition of Each Group
· Group I (G1)
Official A-4 size documents without using formats which reduce the band width of a signal are sent over telephone lines.
Determined in 1968.
Transmission for about 6 minutes at a scanning line density of 3.85 lines/mm.
· Group II (G2)
Using reduction technology in the modulation/demodulation format, an A-4 size document is sent at an official scanning line
density of 3.85 lines/mm for about 3 minutes.
Methods to suppress redundancy are not used.
Determined in 1976.
· Group III (G3)
Method of suppressing redundancy in the image signal prior to modulation is used. An A-4 size document is sent within
about one minute.
Determined in 1980.
· Group IV (G4)
Transmission is via the data network. A method is provided for suppressing redundancy in signals prior to transmission, and
error-free reception of transmission is possible.
The scope of these facsimile applications is not limited simply to transmission of written statements. Through symbiotic
linkages with other communication methods, it can be expected to expand to include integrated services.
176
KX-FPC91
3. Facsimile Call Time Series
As shown in the following diagram, the facsimile call time series is divided into five phases.
Phase A : Call setting
Call setting can be manual/automatic.
Phase B : Pre-message procedure
Phase B is a pre-processing procedure and sequence for confirming the status of the terminal, transmission route, etc., and for
terminal control. It implements terminal preparation status, determines and displays terminal constants, confirms
synchronization status, etc. and prepares for transmission of facsimile messages.
Phase C : Message transmission
Phase C is the procedure for the transmitting facsimile messages.
Phase D : Post message procedure
Phase D is the procedure for confirming that the message is completed and received. For continuous transmission, phase B
or phase C is repeated for transmission.
Phase E : Call retrieval
Phase E is the procedure for call retrieval, that is for circuit disconnection.
4. Concerning Transmission Time
Transmission Time
= Control Time
+ Image Transmission Time
+ Hold Time
Transmission time consists of the following.
Control time:
This is time at the start of transmission when the functions at the sending and receiving sides are confirmed, the
transmission mode is established, and transmission and reception are synchronized.
Image transmission time:
This is the time required for the transmission of document contents (image data). In general, this time is recorded in the
catalog, etc.
Hold time:
This is the time required after the document contents have been sent to confirm that the document was actually sent, and
to check for telephone reservations and/or the existence of continuous transmission.

MODEM CIRCUIT OPERATION
The modem (IC505) has all the hardware satisfying the ITU-T standards mentioned previously.
When the ASIC IC501 (61) is brought to a low level, the modem (IC505) is chip-selected and the resistors inside IC are selected
by the select signals from ASIC (IC501) ADR0-ADR4(pin 83~87). Commands are written through the data bus, and all processing
is controlled by the ASIC (IC501) according to ITU-T procedures. Here, the INT signal dispatched from IRQ (pin 60 of IC505) to the
ASIC (IC501) implements post processing.
This modem (IC505) has an automatic application equalizer. With training signal 1 or 2 at the time of G3 reception, it can
automatically establish the optimum equalizer. The modem (IC505) clock is supplied by pin 55 of ASIC (IC501).
1. Facsimile Transmission/DTMF Line Send
The digital image data on the data bus is modulated in the modem (IC505), and sent from pin 44 via amplifier IC501(2→1),
Analog SW IC509(1→2), amplifier IC511(2→1) and the NCU section to the telephone line.
Refer to 2.3.7.1 CHECK SHEET(P.80).
2. Facsimile Reception
The analog image data which is received from the telephone line passes through the NCU section and enters pin 45 of the
modem (IC505). The signals that enter pin 45 of the modem (IC505) are demodulated in the board to digital image signals, then
placed on the data bus.
In this case, the image signals from the telephone line are transmitted serially. Hence, they are placed on the bus in 8 bit units.
Here, the internal equalizer circuit reduces the image signals to a long-distance receiving level.
This is designed to correct the characteristics of the frequency band centered around 3 kHz and maintain a constant receiving
sensitivity.
It can be set in the service mode.
3. DTMF Transmission (Monitor tone)
The DTMF signal generated in the modem (IC505) is output from pin 44, and the NCU section to the telephone line the same
as facsimile transmission signals.
(DTMF Monitor Tone)
4. Busy/Dial Tone Detection
The path is the same as FAX receiving. When it is detected, the carrier detect bit of the resistor in the modem (IC505) becomes
1, and this status is monitored by ASIC (IC501).

DESCRIPTION OF BLOCK DIAGRAM IN ANALOG SECTION
1. Function
The analog section serves as an interface between the telephone line. The digital board (IC505) for transmission and reception
of FAX signals, switches between the digital board (IC505) and other sections by means of a multiplexer in the NCU section.
The control signals to the individual analog sections are output mainly from ASIC IC501, and the status information for the
various sections is also held in ASIC IC501.
Simple explanations for the various sections are given below.
[NCU Section]
This is the interface between the telephone line and external telephone. This is composed of a bell detection circuit, pulse
dial generation circuit, EXT. TAM OFF-HOOK detect circuit, vox circuit, amplifier circuit for line transmission and reception,
sidetone circuit, etc.
[Modem (IC505)]
This is used for FAX signal tone modulation, DTMF signal transmission, ring tone generation, and line transmission beep
generation. The DTMF signal and beep are placed into the TX system. The ring tone passes through the analog switch and
is output to the speaker via the power amplifier (IC102).

6.8.5.
LINE AMPLIFIER AND SIDE TONE CIRCUIT
The reception signal output from the line transformer T101 is input to pin (2) of IC101 via C111, R111 and then the signal is
amplified at pin (1) of IC101 and sent to the reception system at 10dB.
The transmission signal goes through C122 and R124 and enters IC101-pin (6), where the signal is amplified to about 16.5dB.
Then, it is output from pin (1) of IC101 and transmitted to T101 via C117 and R110. If the side tone circuit is not applied, the
transmission signal will return to the reception amplifier via C111, R111. When the side tone circuit is active, the signal output
from IC101 pin (1) passes through C117, R113, R114, C112 and R112 and goes into the amplifier IC101 pin (3). This circuit
is used to cancel the transmission return signal.

The length of the answering message should be 8~16
seconds.
While the message is being played, the unit starts to
detect the CNG signal.(A)
If the unit detects the CNG signal, it will switch to FAX
receiving and disconnect the external TAM automatically.
After the OGM of the external TAM is finished, the unit
starts to detect approximately 5 seconds of no sound
detection. (B)
If no sound is detected, the unit will switch to FAX
receiving and disconnect the external TAM automatically.
If the unit cannot detect the CNG signal or no sound for
about 30 seconds, the unit will disconnect the line. (C)
Attention 1:
No sound detection lasts 20 seconds after the telephone call is received at the answering machine. If there is no sound for more
than 5 seconds (#701 in the service mode), it switches to the facsimile.
Attention 2:
When the answering machine cannot answer the telephone call because of disconnection or the recording tape is full, the unit
picks up the call after 5 rings (#702 in the service mode). Then it switches to the facsimile.

6.10.2. CIRCUIT OPERATION
The TAM INTERFACE circuit consists of an EXT. TAM HOOK detection circuit, CNG signal from the other party’s detection circuit,
VOX detection circuit (to judge sound/no-sound) and RL101 (to separate EXT. TAM).
1. EXT. TAM HOOK detection circuit
A bell is received at EXT. TAM and EXT. TAM is connected to the line, making a DC LOOP. Then, PC101 detects this voltage.
During detection, PC101 (4) becomes low.
(DC LOOP)
Tip → L101 → LF101 → R144 → L105 → b1 → (EXT.TAM) → a1 → L104→ RL101(5, 3) → PC101(1, 2) → LF101 → L102
→ POS101 → Ring
2. CNG/VOX signal detection circuit
The CNG signal from the other party’s FAX is detected in MODEM IC505 (digital board).
(Signal path)
3. Remote receiving
This is the parallel-connected DTMF signal for the TEL or EXT.TEL mode between T and R. When the other party is a FAX,
the unit switches to FAX receiving.
(Signal Path)
Detects the DTMF signal in the MODEM.

6.13. POWER SUPPLY BOARD SECTION
This power supply board uses the switching regulator method.
[Input Circuit]
The input current goes into the input rectifier circuit through the filter circuit. The filter circuit decreases the noise voltage and the
noise electric field strength.
[Rectifier Circuit]
The input current is rectified by D101,D102,D103 and D104 and charges C106 to make DC voltage. Then it supplies power to the
converter circuit.
[Kick-on voltage circuit]
Bias is applied to the Q101 gate via this circuit when the AC power is turned on and Q101 begins operating.
192
KX-FPC91
The following is an overview of how the power supply unit is controlled.
The control method of this power supply unit is pulse width modulation.
When Q1 is ON, the energy is charged in the transfer primary coil according to E 1. When Q1 is OFF, the energy is output from the
secondary transfer as follows.
L → D1 → Load → L
Then the power is supplied to the Load. When Q1 is ON, power is not output from the secondary side. The output voltage is fed
back in the control IC according to the error amp rectifier. Then depending on how TON is controlled, stabilization occurs. Also, when
the current load becomes too large, in order to decrease the voltage output, the increase in
is controlled and the output voltage
is stabilized.
Therefore, basically the timing: Ton/Toff of Q1 controls the output voltage.
193
KX-FPC91
[Surge Absorber Circuit]
This circuit is for absorbing surge voltage generated by the transformer.
[Control Circuit and Detecting Circuit]
The control circuit amplifies the output with increased voltage detected in the error detecting circuit. Then it drives the main
transistor.
In this power supply, the duty ratio is defined by changing the ON period of the main transistor.
This is shown as follows.
When the output voltage of the 24V circuit increases, the current of the photo coupler PC101 increases, the pulse width of the
output control IC becomes narrower and the ON period of Q101 becomes shorter.
[Over Current Limiter (O.C.L)]
The highest drain current (Q101) is limited by a limiter circuit (IC101) of 24V. The 24V output is limited by this circuit.
[Over Voltage Circuit]
If the 24V output increases because the error detecting circuit or control circuit is broken, IC101 will recognize this signal and output
becomes 0V.
Dummy load method (to quickly check the power supply output)
Refer to 2.3.8 POWER SUPPLY BOARD SECTION(P.84).

6.14. CORDLESS SECTION
6.14.1. CHARGE CIRCUIT
Ultra charge (150 mA) of maximum 4 hours is started soon after the Handset is placed on the base unit. Then it changes to
normal charge (60 mA on the average) of 10 hours. Finally the mode changes to trickle charge (18 mA) to prevent overcharging.
6.14.2. LINE SENDING SIGNAL
The AF signal output from the AF terminal of the RF unit is adjusted to the appropriate level by VR102, then it is input to IC103.
The RX DATA signal from the Handset is muted at this point by IC103 to prevent the RX DATA from leaking onto the line. In this
way the noise is suppressed. IC103 comprises a LPF, a Pre Amp and an expander. The signal compressed by the Handset is
expanded in IC103 to recreate a original signal. The output signal from the expander, then it is input to Digital board by CN101 of
pin 11.
195
KX-FPC91
6.14.3. LINE RECEIVING SIGNAL
The Audio signal is input to CN101 of pin 13 from Digital board. IC103 comprises an amplifier, limiter, mute circuit, compander, and
LPF. It performs signal processing. The audio signal output from pin 7.
At this point (in the talk mode), the DTMF tones, pulse dial tones, and data transferred between the Handset and base unit is input
to the modulator circuit.
6.14.4. RX DATA CIRCUIT
The demodulated data waveform is then input to RX DATA pin 6 of the CPU IC104.
If there is data from the Handset during talk operation, the Handset data is as shown below to prevent the data from leaking
onto the line.
6.14.5. ID CODE SETTING
When the Handset is placed on the base unit, new ID data is output from pin 44 of the CPU after the charge detector operates.
After passing through data amplifier Q230 and the charge terminal, the data is sent to the Handset.
196
KX-FPC91
6.15.1. BLOCK DIAGRAM
The signal flow of the handset is explained in Fig.A. The diagram´s frequency is shown as the first channel´s value.
Receiving Route
1. The RF (Radio Frequency) receiving signal modulated into 900MHz band entered from the antenna is separated into a
transmitting signal in the duplexer constructed from the band pass filter, etc., and enters the receiving route.
2. After it is revised into the appropriate amplitude in the RF amplifier, it drops to the first lower carrier frequency (1st IF
(Intermediate Frequency) Receiving Signal) of 10.7MHz in the first mixer circuit. In this circuit, the signal supplied from the
RXVCO is used. Here, that frequency becomes 891.4000MHz based on the formula (the RF receiving signal frequency
(902.1000MHz) -1st (10.7MHz) = 882.3125MHz).
3. Next, it falls to the next carrier frequency of 450KHz (2nd IF receiving Signal). Here, the signal frequency supplied becomes
10.25MHz based on the formula (the 1st IF receiving signal frequency (10.7MHz) - 2nd IF receiving signal frequency (450KHz)
= 10.25MHz). It is supplied from the reference oscillator through the buffer circuit because the frequency is the same.
4. The 2nd IF receiving signal is demodulated to a receiving voice signal in the detector circuit. It passes through the filter and
amplifier and is sent to the speaker. The signal for the link before communication is also demodulated in the detector circuit,
and input to the CPU through the RX data filter circuit and decoded. Also, the carrier detection circuit detects whether the carrier
signal from the base unit has stopped or not. (Refer to 14.3 Carrier detection circuit for details.)
If the RF receiving signal directly demodulates to a voice frequency band, the signal frequency supplied from RXVCO will
become very close to the receiving signal frequency (the RF receiving signal frequency (902.100MHz) - 2nd IF receiving
frequency (450KHz) = 901.6500MHz). To prevent obstacles in the receiving signal for a weak wave condition, the frequency will
drop in 2 steps. This method is called the Double Super Heterodyne Method and is a technique often used in the FM receiver.
5. The expander circuit decreases the noise from the AF (Audio Frequency) receiving signal demodulated by the detector. An
expander circuit and compander circuit in the communication path decrease the noise. It is similar to the DOLBY system in an
audio product. Here, the explanation of the detailed principle is omitted. After that, an AF signal is output from the speaker
through the side tone control circuit and amplifier circuit. The side tone control circuit makes proper side tone using the
transmission signal from the microphone, and returns it to the speaker.
Transmitting Route
The transmitting signal entered from the microphone goes through the amplifier, compander and filter, is modulated to each
carrier frequency in the TXVCO circuit according to the selected channel, goes through the RF amplifier and duplexer and is
output by the antenna.
Also, the handset operates with a Ni-Cd battery and when there is no communication, power is not supplied and prevents the
battery from running out. Furthermore, the surrounding circuits in the dotted lines in Fig.A. make up the heart of the unit which
is called the RF unit. Usually, it is shielded by a metallic plate. This protects it from exterior obstacles and radiated waves from
the internal components.
This base unit block diagram exchanges the speaker and microphone from the handset block diagram with a telephone line.
The telephone line interface circuit is added and the construction is almost the same.

6.15.3. CARRIER DETECTION CIRCUIT
The handset detects the carrier level (availability of the carrier) from the base unit. The general purposes of it are as follows.
1. To release the standby mode, and detect the availability of the carrier from the base unit.
2. To output an alarm when detecting a weak carrier during talking.
The base unit also detects the carrier level from the handset.
1. To select the proper channel by confirming if another cordless telephone is using that channel or not, and if that channel is noisy
or not.
2. To release the talk mode when the handset becomes out of range.
(After 1 minute of a non-carrier condition, the base unit will release the talk mode.)
The CPU of the base unit and the handset has the input for this detection, called CS (Carrier sensitivity), SQ (Squelch) or 20dB
(20dBuV/m electric field detection).
There are various kinds of signal (terminal) names, but their function is almost the same.
When the carrier detection does not work properly, the base unit and the handset can not communicate and link mutually. For
example, if the problem of cutting off occurs in one minute, the cause is the base unit carrier detection not operating properly.
The basic principle of carrier detection is shown in Fig.C. When the strength of the carrier becomes weak, that signal becomes
noisy. Therefore, the demodulated AF signal also becomes noisy. Depending on the level of that noise, the carrier detection circuit
outputs a high or low signal as follows.
Noise level is higher than the threshold level ---- a High level is output.
Noise level is lower than the threshold level ----- a Low level is output.
200
KX-FPC91
6.15.4. SECURITY CODE
The cordless telephone handset and base unit have individual security codes. If they are not the same, they cannot link mutually.
If the handset of your neighbor´s cordless telephone can link with the base unit of your cordless telephone, your neighbor´s
telephone bill may be charged to yours. There are mainly 2 types of methods as shown below.
Random ID code method
As shown in Fig.D., while the handset is on the base unit being charges, the security code from the base unit is automatically and
randomly sent to the handset via the control terminal in the charge terminals. Furthermore, if another handset is placedon the
charger of the base unit, a security code is written from the base unit and the handset will be available for use. The security code
written from the base unit is randomly selected from thousands of codes and the same code cannot be selected even if neighbor´s
cordless telephone is the same model.
6.15.5. POWER SUPPLY CIRCUIT
Voltage is supplied separately to each block.
201
KX-FPC91
6.15.6. DATA RECEPTION CIRCUIT
The wave detection signal from the RF UNIT has high frequency elements eliminated by a CR filter consisting of R213 and C212.
Then it is amplified by DATA Amp1 and, once again, high frequency elements are eliminated by R218 and C216. After this, the
signal is amplified by DATA Amp2 and input to pin 25 of the CPU.
The data output waveform is a block pulse.
6.15.7. RINGER CIRCUIT
If the ringer volume is set to low and an alarm tone is output from pin 12 of the CPU and input to Q202. Then Q201 is turned off.
If the ringer volume is set to high, Q201 turns on and results in a louder beep tone.
6.15.8. RECEPTION SIGNAL CIRCUIT
The receiver circuit comprises expander IC201.
After being adjusted to the appropriate level by VR202, the signal passes through a 3 kHz LPF and an expander built into
IC202. If a large input is input to the microphone, the gain control built into lowers the gain to reduce the output of the speaker
amplifier. If there is no large input being input to the microphone, the amplifier in IC201 is set to standard gain.
Consequently, the sound of the received audio signal becomes fainter when the user is talking in a loud voice and the side tone
level is lowered. When the user talks more softly, the received audio signal is audible at the standard level.
202
KX-FPC91
6.15.9. RESET/POWER DOWN/BATTERY LOW/ID
When the battery is installed in the Handset, the reset circuit consisting of R217 and inside IC201 functions, inputting a reset signal
to the CPU. This ensures that the unit will operate normally without the user´s needing to switch the power off and on. When the
voltage from the batteries drops to 3.5 V, 3.5 V voltage detector inside IC201 operates and output a battery low signal to the CPU.
This causes the RECHARGE LED to turn on. If voltage continues to drop and reaches 3.2 V, 3.2 V voltage detector inside IC201
operates and outputs a power down signal to the CPU. This causes power to be cut off automatically and prevents the battery from
over discharging.
Q203 is a charge detector that informs the CPU whether or not the handset is currently being charged. During charging, ID data
is sent from the base unit. Q204 receives this ID data and sends it to the CPU.
6.15.10. SENDING SIGNAL
The audio signal from the microphone is amplified by Mic Amp, compander, and 3 kHz LPF built into IC201. It is then mixed with
the TX DATA signal from the CPU, the modulation is adjusted by VR201, and input to the modulator in the RF UNIT.

DATA 0 and DATA 1 is transmitted in LINK requesting DATA (40bit) format first. Then, when LINK OK (ACK-OK) DATA (46bit) is
returned from the Base Unit, it is sent as LINK from DATA after changing the combination of DATA 0 and DATA 1. And the DATA
Delimit is between each Frame as a stop.
The contents of LINK requesting DATA and LINK form DATA are different depending on each operation.
6.15.12.7. PULSE DIAL
When executing Pulse Dial, the Pulse Dial DATA is transmitted from the Handset to the Base Unit in above format. The
combination of DATA 0 and DATA 1 are changed by each Dial No. And the DATA Delimit is between each Frame as a stop. The
number of Frame is 2.
6.15.12.8. TONE DIAL
When executing Tone Dial, Tone Dial DATA is transmitted from the Handset to the Base Unit in above format. The DATA is
changed by Dial No. as same as Pulse Dial. When Tone Dialing, DATA (Continue DATA) that the key is pressed continuously is
sent to the Base Unit during the key is pressed. When depressing the key, the END data is sent finally.
Note:
1,000,000 kinds of the security code are available for this unit. Each time the Handset is set on the cradle of the base unit (for
charging), the CPU automatically change the security code.
