9-431 Change Drum Cartridge (C) Soon
The Drum Cartridge (C) needs to be replaced soon.
Procedure
Replace the Cyan Drum Cartridge (refer to Section 6, Machine Consumables). The problem
is corrected.
YN
Replace the MCU PWB. (PL 13.1).
Return to Service Call Procedures.
9-654 ADC Sensor
The machine logic detected an ADC Sensor operation failure.
Procedure
Check ADJ 9.4. The fail judgement of the ADC Sensor is OK.
YN
There is +5VDC from P/J 536-A13 on the I/F PWB to GND.
YN
Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If
the problem continues replace the MCU PWB (PL 13.1).
Enter dC330 [009-078. The ADC Shutter Solenoid energized (PL 1.3).
YN
Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If
the problem continues replace the MCU PWB (PL 13.1).
Enter dC330 [009-078. There is 0VDC from P/J 536-A8 on the I/F PWB to GND.
YN
Check the wires and connectors. If the check is OK, replace the I/F PWB PL 9.1. If
the problem continues replace the MCU PWB (PL 13.1).
Enter dC330 [009-079. The voltage from P/J 536-A6 to GND changed to 0VDC momen-
tarily.
YN
Check the wires and connectors. If the check is OK, replace the I/F PWB (PL 9.1). If
the problem continues replace the MCU PWB (PL 13.1).
Check the wires and connectors. If the check is OK, replace the, replace the ADC Sensor
Assembly (PL 1.3).
After checking that no failures are detected during normal operation, go to call closeout.
