Step Actions and Questions
17 Test Entrance and Transport Roller drive.
Run the Service Diagnostics Finisher
Transport Motor Test.
Do the Entrance and Transport Rollers
rotate?
18
Print a Test Print.
Does the error still occur?
19 Check the Main Drive Harness.
Are P/J8342 and P/J8304 connected?
20 Print a Test Print.
Does the error still occur?
21
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?
22 Check the Transport Motor resistance.
Is there some amount of resistance
across P8342-2/5(COM) and P8342-1/3/
4/6?
23 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?
24
Replace the Transport Motor.
Print a Test Print.
Does the error still occur?
25 Test the Gate Sensor.
Run the Service Diagnostics Gate Sensor
test.
Does the sensor state change when the
sensor is blocked?
26
Check the Gate Sensor Harness.
Is the harness connected?
27
