These malfunctions are concerned with faulty symptoms as they relate to software, hardware, and
communications. For remedial actions, change the board, check for cable connections, and turn the
Power Switch OFF and ON.
Code
1. Check the connection between PWB-A and UN2, reset the malfunction, and
01 turn OFF and ON the Power Switch.
2. If the same malfunction persists, change PWB-A or UN2.
1. Reset the malfunction and turn OFF and ON the Power Switch.
2. If the same malfunction persists, check the connection between the copier
PWB-A and Finisher PWB-A.
3. If the connection is made properly, unplug the connector between the copier
02
and Finisher and turn OFF and ON the Power Switch.
If the malfunction code display persists, change the copier PWB-A.
If the malfunction is no longer detected, check the connector and, if it is
intact, change the Finisher PWB-A.
1. Reset the malfunction and turn OFF and ON the Power Switch.
2. If the same malfunction persists, check the connection between the copier
PWB-A and A to E below:
A. 2nd Drawer paper source unit
B. 3rd Drawer paper source unit (Paper feed unit/LCC)
C.4th Drawer paper source unit (Paper feed unit/LCC)
D.5th Drawer paper source unit (Paper feed unit)
E. 2-Bin Tray or shift Tray
03
3. If the connection is made properly, unplug the connector between the copier
and A to E and turn OFF and ON the Power Switch.
If the malfunction code display persists, change the copier PWB-A.
If the malfunction is no longer detected, connect the connectors
sequentially and turn OFF and ON the Power Switch. When "C133A" is
detected, check the connector of the corresponding paper source unit
and, if it is intact, change the PWB-A of the unit.
1. Reset the malfunction and turn OFF and ON the Power Switch.
2. If the same malfunction persists, check the harnesses and PJs between PH
10
Unit and PWB-A and, if they are intact, change PH Unit or PWB-A, in that
order.
1. Reset the malfunction and turn OFF and ON the Power Switch.
2. If the same malfunction persists, check the harnesses and PJs between PH
0A
Unit and PWB-A and, if they are intact, change PH Unit or PWB-A, in that
order.
1. Reset the malfunction, turn OFF and ON the Power Switch, and unplug the
power cord and plug it back in.
2. If the malfunction is detected again, check the connection between IC3 on
PWB-A and the EEPROM and, if it is good, change PWB-A.
1B
3. If the malfunction is still detected, change the EEPROM.
For the precautions to be observed when replacing the EEPROM, see
DIS/REASSEMBLY, ADJUSTMENT.
1. Reset the malfunction, turn OFF and ON the Power Switch, and reinstall the
