FIP4.12 CLUTCH PR-REGI

Step
Possible causes:
CLUTCH PR-REGI (PL20.2.22)
Option 550 Paper Feeder 550 PAPER CASSETTE
(PL20.3.50)
PWBA FEEDER 550 (PL20.1.34)
HARNESS ASSY CLSNR1 (PL20.2.31)
HARNESS ASSY CLSNR2 (PL20.1.36)
HARNESS ASSY FDR2 (PL20.1.5)
HVPS/MCU (PL12.1.19)
LVPS (PL12.1.5)
HARNESS ASSY FDR1 (PL12.1.21)
Checking HARNESS ASSY CLSNR1 for continuity
Disconnect P/J855.
1
Disconnect P/J854. Is each cable between J855 and
J854 continuous?
Checking HARNESS ASSY CLSNR2 for continuity
Disconnect P/J85 from PWBA FEEDER 550.
2
Disconnect P/J855.
Is each cable between J85 and J855 continuous?
Checking the resistance of CLUTCH PR-REGI
Is the resistance of the wire wound resistor between P/
3
J854-1 and P/J854-2 of CLUTCH PR-REGI, 172 ohm
+/-10% (at 20 °C)?
Checking PWBA FEEDER 550 for continuity
Disconnect P/J83 from PWBA FEEDER 550.
4
Is there continuity between
P83-3 and P85-3?
Checking HARNESS ASSY FDR2 for continuity
5 Remove HARNESS ASSY FDR2.
Is there continuity between J2083 and J83?
Checking HARNESS ASSY FDR1 for continuity
6 Remove HARNESS ASSY FDR1.
Is there continuity between J20 and J2083?
Checking the power to CLUTCH PR-REGI
Remove EP CARTRIDGE.
7
Is the voltage across P20-10(+) and P20-9(-) on HVPS/
MCU, 24 VDC?
Checking HVPS/MCU for continuity
8 Disconnect P/J10 from HVPS/MCU.
Is there continuity between P10-1 and P20-10?
Check
1 – 110
