Fax control PCB system problem
• Processing with the fax software was
disabled due to a hardware or software problem.
Communication problem between
the operation unit PCB and fax control PCB
• The operation unit PCB did not receive any key request command from
the fax control PCB within 1 minute of
the status change signal turning on.
Then, after resetting the fax machine,
the operation unit PCB again did not
receive any key request command
from the fax control PCB while the
status change signal was held on for
1 minute.
• Abnormal data was received 5 times
in succession in response to the command from the fax control PCB.
• An erroneous FAX READY signal
continued for 3 seconds and, after
resetting the fax machine, an erroneous FAX READY signal continued for
3 seconds again.
Communication problem between
the main PCB and fax control PCB
When the facsimile is in the condition
given below, the correct status was not
received after 5 transmission retries.
• When a communication error, such as
a parity error, occurs while receiving
status.
• When no status is sent back within
100 ms of sending a command.
• When the interval of status reception
data exceeds 30 ms.

1-6-1 Updating the firmware
(1) Updating the firmware on the fax control PCB
Perform the steps below when updating the firmware in the Flash ROM on the fax control PCB.
Firmware updating requires the following tools:
Flash tool assembly (P/N 35968010)
Control ROM IC1 (P/N 2AW29310)
Control ROM IC2 (P/N 2AW29320)
Caution:
• Turn the main switch off and disconnect the power plug from the wall outlet before disconnecting or inserting
connectors.
<Procedure>
1. Turn the main switch off and disconnect the power
plug from the wall outlet.
2. Remove the two screws holding the rear cover and
then the cover.
3. Remove the five screws holding the fax shield cover
and then the cover.
4. Fit control ROM IC1 and control ROM IC2 to the
flash tool assembly.

5. Insert connector CN1 (the one furthest from the
LEDs) on the flash tool assembly into connector CN5
on the fax control PCB.

6. Connect the power plug into the wall outlet.
Upgrading of control ROM IC1 and 2 starts and LED
on the flash tool assembly flashes for 30 seconds.
The LED remains on when upgrading is complete.
7. Disconnect the power plug from the wall outlet.
8. Remove the flash tool assembly from the fax control
PCB.
9. Refit the fax shield cover and rear cover.

Figure 2-2-1 Fax control PCB block diagram
The fax control PCB (FCPCB) controls the overall fax operation.
To transmit a fax, image data scanned by the optical section of the copier is processed by the main PCB (MPCB) and then
sent to the fax control PCB (FCPCB). Received image data is first stored in the bitmap area of the SDRAM IC21 page by
page and compressed using the MH, MR or MMR method. The data is then stored in the image memory area of the SDRAM
IC21 and sent to the modem LSI IC81 to be modulated from digital signal to analog signal before it is sent to the telephone
line via the NCU PCB (NCUPCB).
T o receive a fax, analog image data received from the telephone line via the NCU PCB (NCUPCB) is sent to the modem LSI
IC81 and, after demodulation into digital signals, stored in the image memory area of the SDRAM IC21. The image data is
then decompressed and converted into the bitmap area of the SDRAM IC21 page by page and sent to the ASIC IC71 for
resolution conversion and smoothing, and is passed to the main PCB (MPCB) as print image data.

The NCU PCB (NCUPCB) mainly controls the connection to the telephone line. It consists of the circuits shown in the block
diagram.
The loop current detection/tone signal reception circuit IC30 detects the DC loop current formed at the DC loop/dial pulse
transmission circuit PC80 to determine the status of the telephone line. It also receives tone (DTMF) signals during remote
control. The ring signal detection circuit PC60 detects the ring signals from the telephone line to determine call reception.
The DC loop/dial pulse transmission circuit PC80 turns on and off the DC loop formed in the telephone line to send out dial
pulses (selection signals). The external telephone off-hook detection circuit (T40 and PC40) detects the off-hook state of the
1
telephone connected or the handset*
. The destination identification circuit (JP20, JP21 and JP22) is used by the fax control
PCB (FCPCB) to identify the destination of the NCU PCB (NCUPCB). The accounting pulse elimination circuit L70 removes
signals representing the communication charge information (accounting pulses) before they reach the modem when
2
telephone line is used.*
requests an outside connection to the private branch exchange (PBX) when calling via the PBX.*
This is because accounting pulses obstruct fax communications. The ground start circuit PC10

Keyboard matrix circuit
KEY SENS0-7
The fax operation unit PCB (FOPCB) consists of an LED display matrix circuit and a keyboard matrix circuit. The scan
signals SCAN4 to SCAN7 are output to both matrix circuits from the main PCB (MPCB).
LED lighting signals LEDON0 to LEDON4 are also sent from the main PCB (MPCB) to the LED display matrix circuit. The
LEDs light when they are on the intersection of the lines of the scan signals SCAN4 to SCAN7 and LED lighting signals
LEDON0 to LEDON4.
When a key on the keyboard is pressed, it is identified by tracking the intersection of the lines of the scan signal (SCAN4 to
SCAN7) and the return signal (KEY SENS0 to KEY SENS7) to the main PCB (MPCB).

Figure 2-2-7 Auxiliary power source PCB block diagram
The auxiliary power source PCB (APSPCB) is a switching regulator that converts an AC input to generate 5.2 V DC and 12
V DC. It consists of a switching control circuit, 5.2 V DC output circuit and 12 V DC output circuit.
The rectifier circuit rectifies the full-wave of the AC input using the diode bridge D2. The smoothing capacitor C7 smoothes
out the pulsed current from the diode bridge.
The switching control circuit turns on/off the power MOSFET Q2 with the voltage induced in the controlling coil of the
transformer T1 to switch the current induced in the primary coil of the transformer T1.
The 5.2 V DC output circuit smoothes out the voltage from the current induced in the secondary coil of the transformer T1
via the diode D5 and smoothing capacitors C15 and C91, and outputs a stable 5.2 V DC using the shunt regulator IC1. The
output status of the 5.2 V DC is fed back to the switching control circuit via the photo-coupler PC1. Based on the feedback,
the switching control circuit changes the duty cycle of the pulse that turns power MOSFET Q2 on/off in order to adjust the
5.2 V DC.
The 12 V DC output circuit smoothes out voltage from the current induced in the secondary coil of the transformer T1 via the
diode D6 and smoothing capacitor C19, and generates a stable 12 V DC using the 3-pin regulator IC2.
The relay turns on/off the AC supply to the power source PCB (PSPCB) based on the remote signal from the fax control
PCB (FCPCB).
