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?
Go to Step 6. Repair the Main
Sensor Harness.
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? Go to Step 7. Replace the
Finisher Main
PWB
(page 3-248).
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? Replace the
Finisher Main
PWB
(page 3-248). Replace the
Upper Tray Exit
Sensor

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
