Stacker Lower Tray Failure (Stack Height Sensors) Troubleshooting Procedure
Step Actions and Questions
1 Check the Stacker Lower Tray vertical
transport and belts for obstacles and
deformation.
Are there obstacles or belt wear in the
vertical transport mechanism?
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 the Lower Tray No Paper Sensor
Harness continuity.
1. Disconnect P/J8326 on the Lower Tray
No Paper 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 Stacker 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 Elevator Motor.
Run the Service Diagnostics Stacker Motor
Up and Down tests alternately.
Does the Elevator Motor operate?
10 Check the Elevator Motor connection.
Is P/J8305 connected to the Finisher
Main PWB?
