Check Main Harness continuity.
1. Disconnect PF56B and JF02.
2. Check for continuity at the following:
JF56B-1 <=> JF02-3
JF56B-2 <=> JF02-2
JF56B-3 <=> JF02-1
Are these conductive?
Go to Step 17. Repair the Tray 6
Main Harness.
17
Check for +5 V to the Level Sensor.
Is there +5 V across PF02-3 <=> P/JF04-
2 on the Tray 6 PWB?
Go to Step 18. Replace the Tray
6 PWB
(
page 3-67).
18
Check Level Sensor signal.
1. Open Door J.
2. Open the Upper Feeder Assembly.
Does the voltage across PF02-2 <=>
PF04-2 on the Tray 6 PWB change when
the sensor is blocked?
Go to Step 36. Replace the Level
Sensor
(
page 3-55).
19
Test the Nudger Solenoid.
Run the Service Diagnostics Tray 6 Nudger
Solenoid test.
Does the solenoid activate?
Go to Step 28. Go to Step 20.
20
Check Nudger Solenoid harness
connections.
Are PF59 and PF56 on the Feeder and
Main Harnesses, and JF06 on the Tray 6
PWB connected?
Go to Step 22. Connect and go
to Step 21.
21
Check the repair.
Does the error still occur?
Go to Step 22. Problem solved.
22
Check Nudger Solenoid Harness
continuity.
1. Disconnect PF59 and JF56A.
2. Check for continuity at the following:
PF59-2 <=> JF56A-1
PF59-1 <=> JF56A-2
Are these conductive?
Go to Step 23. Repair the Feeder
Harness.
23
Check Nudger Solenoid Main Harness
continuity.
1. Disconnect PF56A and P/JF06.
2. Check for continuity at the following:
PF56A-6 <=> P/JF06-13
PF56A-5 <=> P/JF06-14
Are these conductive?
Go to Step 24. Repair the
Nudger Solenoid
Main Harness.
24
Check Nudger Solenoid resistance.
Is there some amount of resistance
across PF59-1 and PF59-2?
Go to Step 25. Replace the
Solenoid
(
page 3-50).
