Jam at G (Buffer Path Sensor Static) Troubleshooting Procedure
Step Actions and Questions Yes No
1
Test the Buffer Path Sensor.
Run the Service Diagnostics Buffer Path
Sensor test.
Does the sensor state change?
Go to Step 10. Go to Step 2.
2
Check the Buffer Path Sensor connection.
Are P/J8392 and P/J8318 connected?
Go to Step 4. Connect and go
to Step 3.
3
Print a Test Print.
Does the error still occur?
Go to Step 4. Problem solved.
4
Check Main Sensor Harness connections.
Are P/J8318A and P/J8302 connected?
Go to Step 6. Connect and go
to Step 5.
5
Print a Test Print.
Does the error still occur?
Go to Step 6. Problem solved.
6
Check Buffer Sensor Harness continuity.
1. Disconnect P/J8392 and P/J8318.
2. Check for continuity at the following:
P/J8392-3 <=> J8318B-1
P/J8392-2 <=> J8318B-2
P/J8392-1 <=> J8318B-3
Are these conductive?
Go to Step 7. Repair the Buffer
Sensor Harness.
7
Check Main Sensor Harness continuity.
1. Disconnect P/J8318 from the harness,
and P/J8302A on the Finisher Main
PWB.
2. Check for continuity at the following:
J8318A-3 <=> P/J8302A-13
J8318A-2 <=> P/J8302A-14
J8318A-1 <=> P/J8302A-15
Are these conductive?
Go to Step 8. Repair the Main
Sensor Harness.
