Stacker Lower Tray Failure (Upper Limit Sensor) Troubleshooting Procedure
Step Actions and Questions
2
Check the Actuator installation.
Does the Actuator enter the Upper Limit
sensor sensing area?
3 Test the Lower Tray No Paper Sensor.
Run the Service Diagnostics Lower Tray
No Paper Sensor test.
Does the sensor state change when the
sensor is blocked?
4 Check the Lower Tray No Paper Sensor
Harness connection.
Are P/J8326 and P/J8302B connected?
5 Print a Test Print.
Does the error still occur?
6 Check Main Sensor Harness continuity.
1. Disconnect P/J8326 on the Main Sensor
Harness, and P/J8302B on the Finisher
Main PWB.
2. Check for continuity at the following:
P/J8326-3 <=> P/J8302B-15
P/J8326-2 <=> P/J8302B-16
P/J8326-1 <=>P/J8302B-17
Are these conductive?
7 Check for +5 V to the Lower Tray No Paper
Sensor.
Is there +5 V across J8302B-17 <=>
J8302B-15 on the Finisher Main PWB?
8 Check the Lower Tray No Paper Sensor.
Does the voltage across P8302B-16 <=>
P8302B-15 on the Finisher Main PWB
change when the sensor is blocked?
9 Test the Lower Tray Upper Limit Sensor.
Run the Service Diagnostics Lower Tray
Upper Limit Sensor test.
Does the sensor state change when the
sensor is blocked?
10 Check Lower Tray Upper Limit Sensor
Harness connection.
Are P/J8327 and P/J8302B connected?
11 Print a Test Print.
Does the error still occur?
