The cursor position shows the data to be set.
Pressing # key moves the cursor to the right. If, however, the cursor
is on data number 8, pressing # key shifts the cursor to data number
1 of the next switch number. If the switch number is the final, pressing # key will exit the soft switch mode.
Pressing key moves the cursor to the left. If, however, the cursor is
on data number 1, pressing key shifts the cursor to data number 1
of the former switch number. If the switch number is 1, pressing
key will not move the cursor and the error buzzer will sound.
3
Data setting method
Press the FUNCTION key, and the data at the position of the cursor
will be reversed to 0 when it is 1, or to 1 when it is 0. (If the soft switch
can not be changed at the bit the error buzzer will sound with the
process not received.), When you press the STAR T key or the # key
and the cursor moves to the next switch position, the changes in the
contents of the previous switch position will be saved. If you do not
want to save your changes, press the STOP key.
4
Outputting method of soft switch list
In the soft switch mode, press the COPY/HELP key, and the soft
switch list will be output.
If the recording paper runs out or is clogged, condition is held until
recording paper is prepared, and an error buzzer doesn’t ring.
5
Prohibition against changing individual pieces of data and synchro-
nized data changes
At present, there is no prohibition against changing data individually
and there is also no capability to make synchronized changes to data.
(The ECM may be turned on or off while using image memory.)
2) ROM & RAM check
ROM executes the sum check, and RAM executes the matching test.
If any error occurs, the buzzer will inform it. (Refer to the following table).
Finally, the result will be printed.
Number of buzzer sounds Device checked
1 time <Short sound> MAIN ROM
2 times <Short sounds> S-RAM
3 times <Short sounds> D-RAM
4 times <Short sounds> CPU integrated ROM/RAM
The buzzer beep pattern is: on for 0.25 seconds and then off for 0.25
seconds.

4) Panel key test
This is used to check whether each key is normally operated or not.
According to the key input, LCD is displayed.
1) When the START key is pressed while PANEL KEY TEST is being
displayed, a test will start. Since all of the LEDs will light up in sequence until the test is finished, the LED operation can be checked
as well.
2) Press all of the keys one at a time, but do not press the STOP key.
Every time a key is pressed, the name of that key will appear in the
display.
3) Finally , press the ST OP key. If there was a key you pressed that was
not detected when the STOP key is pressed, PANEL TEST NG! will
be displayed. When all of the keys have been pressed and detected,
PANEL TEST OK! will be displayed.
Then the display will go blank, which is OK. If there was an NG, any
key which was not pressed or not detected will be printed in the result table. (For details about the printout format, see the list function
specifications.)
5) Optical adjust mode
In this mode, the optical system is adjusted. Document feeding can be
started by pressing the STAR T key two times. It can be stopped by pressing the STOP key.
6) Check pattern mode
The effective printing area used will be according to the size specified.
A copy of a pattern will be printed, and the printing will be complete.
7) Signal send mode
This mode is used to send various signals to the circuit during FAX communication. Every push of START key sends a signal in the following
sequence.
[ 1] No signals (CML-ON)

3. Operational description
Operational descriptions are given below:
• Transmission operation
When a document is loaded in stand-by mode, the state of the document sensor is sensed via the ASIC (IC15).
If the sensor signal was on, the motor is started to bring the document into the standby position. With depression of the STAR T key in
the off-hook state, transmission takes place.
Then, the procedure is sent out from the modem and the motor is
rotated to move the document down to the scan line. In the scan
processor, the signal scanned by the CIS is sent to the internal image processor and the AD converter to convert the analog signal into
binary data. This binary data is transferred from the scan processor
to the image buffer within the RAM and encoded and stored in the
transmit buffer of the RAM. The data is then converted from parallel
to serial form by the modem where the serial data is modulated and
sent onto the line.
• Receive operation
There are two ways of starting reception, manual and automatic.
Depression of the START key in the off-hook mode in the case of
manual receive mode, or CI signal detection by the LIU in the automatic receive mode.
First, the CPU(SH2) controls the procedure signals from the modem
to be ready to receive data. When the program goes into phase C,
the serial data from the modem is converted to parallel form in the
modem interface of the 1 fax CPU(SH2) which is stored in the receive buffer of the RAM. The data in the receive buffer is decoded
software-wise to reproduce it as binary image data in the image buffer.
The data is DMA transferred to the recording processor within the
ASIC (IC15) and sent to the LSU on printer PWB.
CPU (SH2) and ASIC (IC15) control printing data, LSU, main motor,
high-voltage circuit, heater control and fan motor.
• Copy operation
T o make a copy on this facsimile, the COPY key is pressed when the
machine is in stand-by with a document on the document table and
the telephone set is in the on-hook state.
First, depression of the COPY key advances the document to the
scan line. Similar to the transmitting operation, the image signal from
the CIS is converted to a binary signal in the DMA mode via the
reading processor which is then sent to the image buffer of the RAM.
Next, the data is transferred to the ASIC in the DMA mode to send
the image data to the printer PWB in order to print. The copying takes
place as the operation is repeated.
(4) Panel PWB
The panel PWB allows input of the operation keys.
(5) Printer PWB
This PWB controls the printer mechanical parts.
This PWB employs 8 bit CPU that is installed on printer PWB.
This CPU control a printer mechanical parts.
(6) LCD PWB
This PWB controls the LCD display.

Basically, the feed roller is rotated 1.5 times.
If interval between PUS and PIN is within 0.5 sec., it is rotated 1 time.
The procedure of clutch control
1
Timer is cleared by PUS ON according to clutch control demand.
2
PUS OFF 100 ms after PUS ON
3
PUS ON again 450 ms after the procedure 1 above.
4
If paper is remained in PIN 500 ms after the procedure 1, the third
PUS ON is stopped.
5
PUS OFF 1.25s after the procedure 1. Clutch control demand OFF
if additional control is cancelled.
6
PUS ON again 1.534s after the procedure 1.
7
PUS OFF 2.334s after the procedure 1.
8
Clutch control demand OFF 3.366s after the procedure 1.
If the paper is not fed normally and the paper in detector signal (PIN_) is
not outputted even with the above operation, the PCU judges it as a
paper jam display is made.
The paper in detector signal (PIN_) is used for the top margin control
signal in addition to jam detection.

d. High voltage unit control
The high voltage unit outputs the following voltages:
• Main charger voltage (DC-950V + AC600V peak to peak)
• Transfer charger voltage (DC+2100V + AC600V peak to peak)
• Developing bias voltage (DC-390V)
The following signals are outputted from the CPU (ASIC) to control the
above voltages.
• MCON
This signal is to turn on/off the main charger.
When this signal is outputted, Q7 is driven to the high impedance state.
Then Q9 conducts to drive transformer T2.
As a result, the main charger voltage is outputted to the secondary
side of the transformer.
• TC/BIASON
This signal is to turn on/off the transfer charger and the developing
bias voltage.
When this signal is outputted, Q3 is driven to the high impedance state.
Then Q5 is conducted to drive T1 to output the transfer charger voltage and developing bias voltage to the secondary side of the transformer.
• PWMSIN
This signal is to control the main charger voltage and the transfer
charger voltage. The PWM pulse of 295.28Hz is outputted.
This pulse waveform adds the AC component to the main charger volt-
age and the transfer charger voltage.
By changing the pulse duty of this signal, the main charger voltage
and the transfer charger voltage are controlled (during temperature
correction operation).
When the pulse duty of this signal is changed, the collector currents of
Q4 and Q8 are changed. Therefore, the base current of Q9 and the
drive current of transformer T2 are changed to change the main charger
voltage and the transfer charger voltage.

1) Signal functions
PMCLK
Clock signal for driving the scanning (polygon) motor . (1.18KHz/770Hz)
PMD
Scanning motor ON/OFF signal.
APCSTT
Used to start the laser beam generation circuit.
SYNC
This signal is outputted when the laser beam scanned by the laser
beam sensor signal is sensed by sensor (Photo diode D601).
Used for the left margin control.
VIDEO
This signal is used to control the laser diode emitting.
Not only when the laser beam is emitted to perform the LEND proc-
ess, but also when the laser beam is emitted as image data, ASIC
controls and the signal is outputted from video terminal.
Fig. 9
2) Laser beam power control
The laser beam power is controlled in the laser emitting unit PWB.
This circuit functions to keep the laser beam output power at a constant
level.
The laser beam output is monitored with photo diode D602 for monitor.
When the laser beam output rises above the specified value, the impedance of photo diode D602 is decreased to decrease the monitor input
(3PIN) voltage of the laser diode control IC (IC601).
Then the laser diode (LTO28GS) drive voltage is decreased to decrease
the laser beam output to the specified level.
When the laser beam output is decreased below the specified level, the
contrary operation are performed.

3) Starting operation
Warm-up operation of laser scanning is described below.
The operation is made when the cover is closed from the open state,
and is made before starting printing.
The PMCLK signal is the clock signal for scanner motor speed control.
It is rectangular waveform of 1.18kHz.
1
The PMD_signal is to turn on/off the scanner motor . When this signal
is outputted, the scanner motor is operated.
2
After 2 sec of starting the scanner motor, the laser power control
signal APCSTT and the laser diode ON signal VIDEO (LEND) are
outputted to output laser beams.
3
After 0.5sec from outputting the VIDEO (LEND) signal and turning
on the laser diode, the LEND process operation is started.
Clock of 1,18KHz is always outputted.
0.5sec
After about 0.5sec of turning on the LEND_ signal,
the LEND process is started.

4) LEND process operation
The LEND process operation means outputting the HSYNC (HSYNC_)
signal for left margin control.
To control the left margin, the scanning position of the scanning mirror
on the virtual area of the left side out of the margin must be precisely
detected when the scanning motor reaches the stable rpm. Therefore,
the dummy laser beam must be outputted to detect the position.
The laser beam scanning position is detected by the laser beam sensor,
and the SYNC signal is outputted.
The dummy laser beam is outputted for every scanning of one line only
when the scanning position of the scanning mirror is outside the left
area of virtual paper. (The laser is forcibly turned on by the PCU when
the laser beam scanned by the scanning mirror come in front of the
laser beam sensor (left margin reference).)
Note: The laser beam is not outputted continuously during printing op-
eration of one paper. It repeated ON and OFF for every scanning
of one line.
The laser beam is outputted only when the LEND process for controlling the print left margin is made and when the print image is
drawn on the photoconductor.
• Laser control signal
LEND signal is controlled based on HSYNC signal.
For simultaneous APC control, SAMP signal is also controlled.
These timings are made by ASIC. The line-end-of f section is set by the
register.

When the LEND_ signal is on, the dummy laser beam is outputted,
and the scanned laser beam is detected by the laser beam sensor to
output the SYNC signal. When the SYNC signal is outputted, the
CPU detects the scanning position.
2
At the rising of the SYNC signal, the CPU turns off the LEND_signal.
By this, the dummy laser beam is turned off. When the CPU detects
the scanning position with the SYNC signal, the dummy laser beam
becomes unnecessary.
3
The draw signal Video_ is made from the DDA TA_ signal of one line
outputted from the ASIC. When it is outputted, the laser beam is turned
on off accordingly. This corresponds to the making of latent electrostatic images on the photoconductor drum.
4
When making of latent electrostatic images for one line is completed,
the CPU turns on the LEND_ signal before the output timing of the
SYNC.

The laser diode control board is driven in synchronization with the VIDEO
signal sent from the CPU board.
By the operation of the laser diode control board, infrared laser beams
of 780nm are outputted from the laser diode and made in parallel by the
collimator lens, and focused onto the scanning motor by the first cylinder lens.
The scanning mirror rotation is controlled by the scanning motor to be
constant at 11811rpm (600dpi) and 8000rpm (400dpi), and the laser
beam is directed to the main scanning direction.
The scanning motor is of six-surface, and six-line print is made for one
rotation of the scanning motor. The laser beam reflected by the scanning mirror is directed to the curved mirror by the first reflection mirror.
Before reaching the curved mirror, the laser beam enters the photo sensor on the start position detector board, making vertical synchronization
and print data synchronization (generating the SYNC signal).
The curved mirror directs the laser beam to the second reflection mirror
in parallel and in even interval regardless of difference in angles of incidence from the first reflection mirror. The laser beam reflected by the
second reflection mirror ia passed through the second cylinder lens to
reach the photoconductor drum.
The second cylinder lens corrects blur of the images caused by variations in the installing angle due to the two-surface scanning mirror, providing stable laser beams to the photoconductor drum for each line.

h. Fusing unit control
The fusing section is heated by the heater lamp (400W). The heater
lamp is controlled (turned on/off) to keep the optimum temperature. The
following signals are outputted by the ASIC and CPU for control.
1) Signal functions
• HLON
This signal is to turn on/off the heater lamp. When this signal is
outputted, photo triac PD101 turns on to turn on triac T2. Then an AC
power is supplied to the heater lamp to turn on the heater lamp.
• RTH
This is the output signal of the thermistor which detects the surface
temperature of the heat roller. It is inputted to the CPU. The heater
lamp is turned on/off depending on the value of RTH voltage.
5 – 14
Page 51
FO-2970MU
2) Protect against overheat
Though the heater lamp ON signal (HLON) is normal, if triac PD101 and
T2 are kept ON, overheat may result.
To prevent against this, temperature fuses are used.
When the fusing roller surface temperature exceeds about 187 degrees
C, the temperature fuse blows off to open the 12V power line which
drives the power relay RY101, opening the power line for the photo triac
PD101 and triac T2. Therefore, the power is not supplied to the heater
lamp.
A temperature fuse is also provided in the heater lamp power line. In
case of overheating, the heater lamp power line is opened directly.
3) Timing of temperature detection and heater control
As shown by the following timings, four values of software thermistor
voltage are input as A/D conversion values. The mean value of two
medians among these four is regarded as the newest thermistor value
(temperature).
• The value is compared with the temperature (155°C) control value
every 100 ms.
• If the value is higher than 155°C, the heater becomes OFF. If lower,
the heater becomes ON.
• The heater ON timing is in accordance with the timing of Power Zero
Cross interrupt.
Heater ON/OFF Control
Heater ON/OFF Control
• After printing, temperature is not controlled.
• Fan motor starts revolving from the beginning of temperature control
and stops 120 seconds after printing is finished.
T emperature control is not started from the start of printing because the
first copying time should be within 28 seconds.

k. Top margin control
T op margin is set according to the number of lines (the number of HSYNC
interrupt) from detail paper Pin On to LASER input.
The interval between Pin On and point D is 52.6747 mm.
The interval between Point D and point B is: 27.33 (C-D) + 8.3769 (B-C)
= 35.7069 mm
If top margin is 4 mm,
52.6747 - 35.7069 + 4 = 20.9678 m
In case of the actual software processing, chattering of the sensor is
considered to be observed for 9 msec.
The processing speed is 50 mm/sec; while chattering is being observed,
paper is fed by 0.45 mm (9 x 50/1000 = 0.45 mm).
In order to gain top margin of 4 mm, printing data should be processed
after paper is fed by 20.5178 mm (20.9678 – 0.45 = 20.5178 mm) following PIN On detection.
The base machine resolution in the sub-scanning direction is 391.16
dpi; If the value 20.5178 mm is converted into the number of lines, 315.9
lines are obtained from 391.16 x 20.5178/25.4. Accordingly the software set value is considered to be based on 316 lines.
Similarly, considering from the fact that resolution of PC printing is 600
dpi, the number of lines is 484.6 lines (600 x 20.5178/25.4=484.6).
The software set value is based on 485 lines.

(4) MODEM control block
1) INTRODUCTION
Conexant's FM336 modem is a V.34 half-duplex modem. It supports
Group 3 facsimile transmission/reception at speeds up to 33,600bps in
the V.34 half-duplex mode. In order to optimize the modem configuration for the line conditions, this modem uses V.34 technology. It connects at an optimally selected data rate so that speeds from 2,400bps to
33,600bps can be supported.
This modem can be used on the general public telephone network using
a network control unit (NCU) line termination device. This modem conforms to ITU-T V .17, V.21, V.23, V.27ter, V .29, and V.34 specifications. It
also complies with V.8 and T.30 binary signaling conditions. This modem supports HDLC internally. Therefore, products using built-in error
correction and the T.30 protocol do not need an external serial input/
output (SIO) line on DTE. This modem can execute HDLC framing, as
specified in T.30, at all data rates. Since it can perform zero insertion/
deletion and CRC tasks, this allows enhanced SDLC/HDLC frame operation. The FSK flag pattern detector facilitates FSK detection during
high-speed reception.
This modem features a programmable DTMF transmitter/receiver that
operates in tone mode, and three programmable tone detectors. This
modem is primarily suited to use in small system designs in such environments as work plants, offices, and homes because of its low power
consumption and small size. This modem is packaged in a 100-pin PQFP .

[4] Circuit description of power supply
PWB
1. Noise filter circuit
The filter part removes noises generated from the power unit to avoid
noise release outside and prevent external noises from entering.
Excessive surge such as thunder is prevented by varistor Z1.
2. Rectified smoothing circuit
The rectified smoothing circuit rectifies AC input at diodes D10, 11, 12,
and 13, and then smoothens it at capacitor C5 to supply DC voltage to
the switching part.
3. Switching part
This circuit adopts the ringing choke converter system of self-excited
type.
By repeating ON/OFF of MOS FETQ1, this system converts DC voltage
supplied from the rectified smoothing part into high-frequency pulse,
stores energy in the primary winding of transformer T1 during ON period, releases energy to the secondary winding during OFF period, and
supplies power.
Frequency changes according to output load; As load increases, ON
period becomes longer.
Constant voltage is controlled by applying feedback to the control circuit
via photo coupler from 24 V output.
The overcurrent protective circuit detects prolonged ON period caused
by excessive output load, lengthens Q1 OFF period by using the control
circuit, and restricts energy stored in the primary winding of transformer
T1.
Increase of the secondary output voltage 24 V is led to the overcurrent
condition by turning on power zener diode D202 between 24 V output
and GND.
Thus overvoltage is protected by operating the overcurrent protective
circuit of the control circuit.
4. 24 V circuit
To supply output, transformer T1 output is rectified and smoothened
with the use of diode D101 and capacitor C101. Voltage is controlled by
Volume VR101.
5. +5 V circuit
Transformer T1 output is rectified and smoothened with the use of diode
D301 and capacitor C301 to stabilize +5 V output by using 3-terminal
regulator IC301.
6. Heater circuit
To maintain the optimal temperature, the heater lamp is controlled by
HLON signal from the control panel.
This HLON signal is to switch ON/OFF the heater lamp. If this signal is
input LOW, PC2 is switched ON, resulting TRIACK TRA1 ON.
Accordingly, AC power is supplied to the heater lamp to switch the heater
lamp ON.
7. Zero cross circuit
When AC input reaches the zero cross point (0 V), PC3 is switched ON.
When Q501 is switched ON, the zero cross signal is output to the control panel.
