Error Messages, Codes, and Procedures 3-139
5
Check Transport Motor 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?
Go to Step 6. Repair the
Transport Motor
Drive Harness.
6
Check the Transport Motor resistance.
Is there some amount of resistance
across P8342-2/5(COM) and P8342-1/3/
4/6?
Go to Step 7. Replace the
Transport Motor
(
page 3-222).
7
Check for +24 V to the Transport Motor.
Is there +24 V across J8304-16 <=>
ground and J8304-18 <=> ground on the
Finisher Main PWB?
Go to Step 8. Replace the
Finisher Main
PWB
(
page 3-248).
8
Replace the Transport Motor.
Print a Test Print.
Does the error still occur?
Replace the
Finisher Main
PWB
(
page 3-248).
Problem solved.
9
Test the Gate Sensor.
Run the Service Diagnostics Gate Sensor
test.
Does the sensor state change when the
sensor is blocked?
Go to Step 15. Go to Step 10.
10
Check the Gate Sensor Harness.
Are P/J8432 and P/J8376 connected?
Go to Step 12. Connect and go
to Step 11.
11
Print a Test Print.
Does the error still occur?
Go to Step 12. Problem solved.
12
Check Gate Sensor Harness continuity.
Disconnect P/J8432 and P/J8376.
Check for continuity at the following:
P/J8432-3 <=> P/J8376-1
P/J8432-2 <=> P/J8376-2
P/J8432-1 <=> P/J8376-3
Are these conductive?
Go to Step 13. Repair the Gate
Sensor Harness.
13
Check for +5 V to the Gate Sensor.
Is there +5 V across P8376-3 <=> P8376-
1 on the Finisher Main PWB?
Go to Step 14. Replace the
Finisher Main
PWB
(
page 3-248).
