Troubleshooting Procedure
Steps Actions and Questions
1 Check Clutch/Sensor Harness 1:
1. Disconnect P/J855.
2. Disconnect P/J853.
3. Test each conductor between J855 <=>
J853 for continuity.
Is each conductor continuous?
2 Check Clutch/Sensor Harness 2:
1. Disconnect P/J85 from the 550-Sheet
Feeder PWBA.
2. Disconnect P/J855.
3. Test each conductor between J85 <=>
J855 for continuity?
Is each conductor continuous?
3 Check the resistance of the Feed Clutch
Assembly:
Measure the resistance of the clutch
between P/J853-1 <=> P/J853-2.
Does the resistance measure 172 ohm
+/-10% (at 20° C)?
4 Check the 550-Sheet Feeder PWBA:
1. Disconnect P/J83 from the 550-Sheet
Feeder PWBA.
2. Test the following points for continuity:
P83-1 <=> P85-1
P83-2 <=> P85-2
Are both continuous?
