Jam at G (Buffer Path Sensor ON) Troubleshooting Procedure (Continued)
Step Actions and Questions
2 Check the paper path.
1. Open Door G.
2. Remove the Top Cover.
3. Remove the Top L/H Cover.
4. Open the Upper Exit Chute.
Are the Buffer and Pinch Rollers clean,
roll freely, and installed correctly?
3
Test the X'port Entrance Sensor.
Run the Service Diagnostics Finisher
Transport Entrance Sensor test.
Does the state change when white
paper is placed over the sensing area?
4
Check the harness connections.
Are P/J8319 and P/J8303B of the X'port
Entrance Sensor, and P/J8302A on the
Main SNR harness connected?
5
Print a Test Print.
Does the error still occur?
6 Check the sensor harness continuity.
1. Disconnect P/J8319 and P/J8303B on
the X'port Entrance Sensor Harness.
2. Check for continuity at the following:
J8319-3 <=> J8303B-1
J8319-2 <=> J8303B-2
J8319-1 <=> J8303B-3
Are these conductive?
7 Check Main Sensor Harness continuity.
Disconnect P/J8303A on the Main Sensor
Harness, and P/J8302A on the Finisher
Main PWB.
Check for continuity at the following:
J8303A-3 <=> J8302A-1
J8303A-2 <=> J8302A-2
J8303A-1 <=> J8302A-3
Are these conductive?
8 Check for +5 V to the Entrance Sensor.
Is there +5 V across J8302A-3 <=>
J8302A-1 on the Finisher Main PWB?
9 Check the Entrance Sensor signal.
Does the voltage across P8302A-2 <=>
P8302A-1 on the Finisher Main PWB
change when the sensor is blocked?
