Check HARNESS ASSY FDR for continuity
Check the following for continuity.
19
J47-13PIN <=> P475-2PIN
J47-14PIN <=> P475-1PIN
Check CLUTCH ASSY TURN for resistance value
20 Remove the CLUTCH connector J475
Is J475-1PIN <=> J475-2PIN less than 200Ω?
Check HARNESS ASSY DRV2 for continuity
21
Is J12-9PIN <=> J42-22PIN check continuous?
Check SOLENOID FEED for operation
22 Does the Feed Gear in the Feeder run when printing 1
sheet?
Check SOLENOID FEED
Does the SOLENOID FEED function normally?
23 Using SOLENOID FEED diagnostic tool, check by
Diagnostic Output Test.
In the test, close the INTERLOCK SW.
Check PWBA HNB DRV for signal
24
Is P/J47-11PIN <=> P/J60-2PIN +24VDC?
Check HARNESS ASSY FDR for continuity
