Step Action and Question
Continuity of the PWBA FEEDER550
No
1. Disconnect the connector P/J83 on the PWBA
4 FEEDER550.
2. Check continuity between the following terminals:
P83-3 ↔ P85-3
Is there continuity between P83-3 ↔ P85-3?
♦
Continuity of the HARNESS ASSY FDR2
1. Remove the HARNESS ASSY FDR2.
5
2. Check the wiring between J2083 ↔ J83 for
continuity.
♦ Is there continuity between J2083 ↔ J83?
Continuity of the HARNESS ASSY FDR1
1. Remove the HARNESS ASSY FDR1.
6
2. Check the wiring between J20 ↔ J2083 for
continuity.
Is there continuity between J20 ↔ J2083?
♦
Power supply to the CLUTCH PR-REGI
1. Remove the Imaging Cartridge.
