Replace Photoconductor Unit.
Does the error recur when the power is turned
ON?
Go to Step [3]. End of procedure
3
Power supply check to PWBA MCU
Are the following power voltages being
supplied to PWBA MCU from LV/HVPS?
J410-1 ↔ J410-2: 3. 3 VDC
J410-3 ↔ J410-4: 5 VDC
J410-5/6 ↔ J410-7/8: 24 VDC
Replace PWBA
MCU. (p.432)
Go to Step [4].
4
Continuity check of HARNESS ASSY MAIN
Disconnect P/J410 from PWBA MCU and P/
J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J410-1 ↔ J502-1
J410-2 ↔ J502-2
J410-3 ↔ J502-3
J410-4 ↔ J502-4
J410-5 ↔ J502-5
J410-6 ↔ J502-6
J410-7 ↔ J502-7
J410-8 ↔ J502-8
Replace LV/
HVPS. (p.435)
