Step Actions and Questions
10
Test the Finisher Transport Motor.
Run the Service Diagnostics Finisher
Transport Motor Test.
Does the motor rotate normally?
11 Test the Entrance Roller drive.
Run the Service Diagnostics Finisher
Transport Motor Test.
Does the Entrance Roller rotate?

Check Main Drive Harness continuity.
1. Disconnect P/J8342 and P/J8304.
2. Check for continuity at the following:
J8342-1 <=> J8304-23
J8342-2 <=> J8304-16
J8342-3 <=> J8304-25
J8342-4 <=> J8304-27
J8342-5 <=> J8304-18
J8342-6 <=> J8304-29
Are these conductive?
16
Check the Transport Motor resistance.
Is there some amount of resistance
across P8342-2/5(COM) and P8342-1/3/
4/6?
17 Check for +24 V to the Transport Motor.
