Step Actions and Questions
7
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?
8 Check the Transport Motor resistance.
Is there some amount of resistance
across P8342-2/5(COM) and P8342-1/3/
4/6?
9 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?
10 Replace the Transport Motor.
Run the Service Diagnostics Finisher
Transport Motor Test.
Does the error still occur?
11 Test the Upper Tray Exit Sensor.
Run the Service Diagnostics Upper Tray
Exit Sensor test.
Does the sensor state change?
12 Check the Sensor Harness connections.
Are P/J8321 and P/J8312 on the sensor
harness, and P/J8312 and P/J8302 on
the Main Sensor Harness connected?
13 Print a Test Print.
Does the error still occur?
14 Check Exit Sensor Harness continuity.
1. Disconnect P/J8321 and P/J8312.
2. Check for continuity at the following:
P/J8321-3 <=> J8312B-1
P/J8321-2 <=> J8312B-2
P/J8321-1 <=> J8312B-3
Are these conductive?
