Step
Checking OPTION FEED MOTOR
27 Check if an error occurs though the OPTION FEED MOTOR
was replaced with a new one.
Checking CLUTCH ASSY TURN TRAY 2 for operation
28 Does the TURN ROLL in the FEEDER run when printing 1
sheet?
Checking CLUTCH ASSY TURN TRAY 2
Does the CLUTCH ASSY TURN TRAY 2 function normally?
29 Using CLUTCH ASSY TURN 2 diagnostic tool, check by
Digital Output Test.
In the test, close the INTERLOCK SW.
Checking PWBA OPTFDR for signal
30
Is P/J82-13PIN <=> P/J81-1PIN +24VDC?
Checking HARNESS ASSY FDR2T for continuity
Check the following for continuity.
31
J82-13PIN <=> P825-2PIN
J82-14PIN <=> P825-1PIN
Checking CLUTCH ASSY TURN TRAY 2 for resistance
value
32
Remove the CLUTCH connector J825
Is J825-1PIN <=> J825-2PIN less than 200Ω?
Checking HARNESS ASSY OPFPLG/HARNESS ASSY
OPFREC/HARNESS ASSY OPFMAIN for continuity
33
Check the following for continuity.
J81-22PIN<=>J810-A5PIN<=>J210-B5PIN<=>J21-5PIN
Checking SOLENOID FEED TRAY 2 for operation
34 Does the FEED GEAR in the FEEDER run when printing 1
sheet?
Checking SOLENOID FEED TRAY 2
Does the SOLENOID FEED TRAY 2 function normally?
35 Using SOLENOID FEED TRAY 2 diagnostic tool, check by
Digital Output Test.
In the test, close the INTERLOCK SW.
Checking PWBA OPTFDR for signal
36
Is P/J82-11PIN <=> P/J81-1PIN +24VDC?
Checking HARNESS ASSY FDR2T for continuity
Check the following for continuity.
37
J82-11PIN <=> P824-2PIN
J82-12PIN <=> P824-1PIN
Checking SOLENOID FEED TRAY 2 for resistance value
38 Remove the SOLENOID connector J824
Is J824-1PIN <=> J824-2PIN less than 100Ω?
Checking HARNESS ASSY OPFPLG/HARNESS ASSY
OPFREC/HARNESS ASSY OPFMAIN for continuity
39
Check the following for continuity.
J81-20PIN<=>J810-A7PIN<=>J210-B7PIN<=>J21-7PIN
