Jam at G (Buffer Path Sensor ON) Troubleshooting Procedure (Continued)
Step Actions and Questions
21 Print a Test Print.
Does the error still occur?
22 Check the Sensor Harness continuity.
1. Disconnect P/J8432 and P/J8376.
2. Check for continuity at the following:
J8432-3 <=> J8376-1
J8432-2 <=> J8376-2
J8432-1 <=> J8376-3
Are these conductive?
23 Check +5 V to the Gate Sensor.
Is there +5 V across P8376-3 <=> P8376-
1 on the Finisher Main PWB?
24 Check the Gate Sensor.
Does the voltage across P8376-2 <=>
P8376-1 on the Finisher Main PWB
change when the sensor is blocked?
25 Test the Buffer Gate Solenoid.
Run both Service Diagnostics Buffer Gate
tests.
Does the Buffer Gate operate?
26 Check Main Drive Harness connections.
Are P/J8394 and P/J8304 connected?
27
Print a Test Print.
Does the error still occur?
28 Check Main Drive Harness continuity.
1. Disconnect P/J8394 and P/J8304.
2. Check for continuity at the following:
J8394-1 <=> J8304-35
J8394-2 <=> J8304-34
J8394-3 <=> J8304-36
Are these conductive?
29 Check for +24 V to the Buffer Gate
Solenoid.
Is there +24 V across J8304-34 <=>
J8304-36 on the Finisher Main PWB?
30 Replace the Buffer Gate Solenoid.
Print a Test Print.
Does the error still occur?
31 Test the Registration Motor.
Run the Service Diagnostics Finisher
Registration Motor Test.
Does the motor rotate normally?
