continuity.
1. Disconnect P/J8312 from the harness,
and P/J8302A on the Finisher Main
PWB.
2. Check for continuity at the following:
J8312A-3 <=> P/J8302A-7
J8312A-2 <=> P/J8302A-8
J8312A-1 <=> P/J8302A-9
Are these conductive?
6 Check for +5 V to the Upper Tray Exit
Sensor.
Is there +5 V across J8302A-9 <=>
J8302A-7 on the Finisher Main PWB?
7 Check the Upper Tray Exit Sensor signal.
Does the voltage across P8302A-8 <=>
P8302A-7 on the Finisher Main PWB
change when the sensor is actuated?
8 Test the Finisher Transport Motor.
Run the Service Diagnostics Finisher
Transport Motor Test.
Does the motor rotate normally?
9 Test Entrance and Transport Roller drive.
Run the Service Diagnostics Finisher
Transport Motor Test.
Do the Entrance and Transport Rollers
rotate?
10 Check the Finisher Transport Motor Main
Drive Harness.
Are P/J8342 and P/J8304 connected?
11 Print a Test Print.
Does the error still occur?
12 Check Main Drive Harness continuity.
1. Disconnect P/J8342 and P/J8304.
2. Check for continuity at the following:
P/J8342-1 <=> P/J8304-23
P/J8342-2 <=> P/J8304-16
P/J8342-3 <=> P/J8304-25
P/J8342-4 <=> P/J8304-27
P/J8342-5 <=> P/J8304-18
P/J8342-6 <=> P/J8304-29
Are these conductive?
