1
Continuity of the HARNESS ASSY CLSNR1
1. Disconnect the P/J855.
(Refer to “Connectors (p.406)”)
2. Disconnect the P/J853.
3. Check continuity between J855 ↔ J853.
♦Does each wiring between J855 ↔ J853 have
continuity?
Go to Step 2
Replace the
HARNESS
ASSY
CLSNR1
2
Continuity of the HARNESS ASSY CLSNR2
1. Disconnect the connector P/J85 on the PWBA
FEEDER550.
2. Disconnect the P/J855.
3. Check continuity between J85 ↔ J855.
♦Does each wiring between J85 ↔ J855 have
continuity?
Go to Step 3
Replace the
HARNESS
ASSY
CLSNR2
3
CLUTCH ASSY PH
1. Measure the resistance between P/J853-1 ↔ P/J853-
2.
♦Is the coil resistance of the CLUTCH ASSY PH
172Ω ± 10% (20°C)?
Go to Step 4
Replace the
CLUTCH
ASSY PH
4
Continuity of the PWBA FEEDER550
1. Disconnect the connector P/J83 on the PWBA
FEEDER550.
2. Check continuity between the following terminals:
P83-1 ↔ P85-1
♦Is there continuity between P83-1 ↔ P85-1?
Go to Step 5
Replace the
PWBA
FEEDER550
5
Continuity of the HARNESS ASSY FDR2
1. Remove the HARNESS ASSY FDR2.
2. Check the wiring between J2083 ↔ J83 for
continuity.
♦Is there continuity between J2083 ↔ J83?
Go to Step 6
Replace the
HARNESS
ASSY FDR2
6
Continuity of the HARNESS ASSY FDR1
1. Remove the HARNESS ASSY FDR1.
2. Check the wiring between J20 ↔ J2083 for
continuity.
♦Is there continuity between J20 ↔ J2083?
Go to Step 7
Replace the
HARNESS
ASSY FDR1
7
Power supply to the CLUTCH ASSY PH
1. Remove the Imaging Cartridge.
2. Measure the voltage between P20-10 ↔ P20-9 on
the
HVPS/MCU.
♦24 VDC between P20-10 ↔ P20-9?
Replace the
CLUTCH
ASSY PH
Go to Step 8
8
Continuity of the HVPS/MCU
1. Disconnect P/J10 from the HVPS/MCU.
2. Check continuity between P10-1 ↔ P20-10.
♦Is there continuity between P10-1 ↔ P20-10?
Go to 3.4.1
LVPS (p.111)
Replace the
HVPS/MCU
