Step
Checking HARNESS ASSY DRV1 for continuity
Check the following for continuity.
15 J41-30PIN <=> J11-11PIN
J41-31PIN <=> J11-10PIN
J41-33PIN <=> J11-8PIN
Checking CLUTCH ASSY TURN for operation
16
Does the Turn Roll in the Feeder run when printing 1 sheet?
Checking CLUTCH ASSY TURN
Does the CLUTCH ASSY TURN function normally?
17 Using CLUTCH ASSY TURN diagnostic tool, check by
Digital Output Test.
In the test, close the INTERLOCK SW.
Checking PWBA HBN DRV for signal
18
Is P/J47-13PIN <=> P/J60-2PIN +24VDC?
Checking HARNESS ASSY FDR for continuity
Check the following for continuity.
19
J47-13PIN <=> P475-2PIN
J47-14PIN <=> P475-1PIN
Checking CLUTCH ASSY TURN for resistance value
20 Remove the CLUTCH connector J475
Is J475-1PIN <=> J475-2PIN less than 200Ω?
Checking HARNESS ASSY DRV2 for continuity
21
Is J12-9PIN <=> J42-22PIN continuous normally?
Checking OPTION FEED MOTOR for operation
22 Does the OPTION FEED MOTOR run when printing 1
sheet?
Checking OPTION FEED MOTOR
Does the OPTION FEED MOTOR function normally?
23
Using diagnostic tool, check by Digital Output Test.
In the test, close the INTERLOCK SW.
Checking PWBA OPTFDR for signal
24
Is P/J84-3PIN <=> P/J81-1 +24VDC?
Checking PWBA OPTFDR for signal
25
Is P/J81-2PIN <=> P/J81-1PIN +24VDC?
Checking HARNESS ASSY OPFPLG/HARNESS ASSY
OPFREC/HARNESS ASSY OPFMAIN for continuity
Check the following for continuity
J81-4PIN<=>J810-B10PIN<=>J210-A10PIN<=>J21-23PIN
26 J81-5PIN<=>J810-B9PIN<=>J210-A9PIN<=>J21-22PIN
