Stacker Lower Trail Failure (Stacker Encoder Sensor) Troubleshooting Procedure
Step Actions and Questions
12
Check for +5 V to Stack Height Sensor 2.
Is there +5 V across J8302A-18 <=>
J8302A-16 on the Finisher Main PWB?
13 Check Stack Height Sensor 2 signal.
Does the voltage across P8302A-17 <=>
P8302A-16 on the Finisher Main PWB
change when the sensor is blocked?
14 Test the Stacker Encoder Sensor.
Run the Service Diagnostics Stacker
Encoder Sensor test.
Does the sensor state change when the
Elevator Motor Belt is moved by hand
rotating the Encoder Wheel?
15 Check Stacker Encoder Sensor Harness
connections.
Are P/J8328 and P/J8302B connected?
16 Print a Test Print.
Does the error still occur?
17 Check Stacker Encoder Sensor Harness
continuity.
1. Disconnect P/J8328 on the harness, and
P/J8302B on the Finisher Main PWB.
2. Check for continuity at the following:
P/J8328-3 <=> P/J8302B-12
P/J8328-2 <=> P/J8302B-13
P/J8328-1 <=> P/J8302B-14
Are these conductive?
18 Check for +5 V to Stacker Encoder Sensor.
Is the voltage across J8302B-14 <=>
J8302B-12 on the Finisher Main PWB?
19 Check Stacker Encoder Sensor signal.
Does the voltage across P8302B-13 and
P8302B-12 on the Finisher Main PWB
change when the sensor is blocked?
20 Test the Elevator Motor.
Run the Service Diagnostics Stacker Motor
Up and Down tests alternately.
Does the Elevator Motor operate?
21 Check the Elevator Motor connection.
Is P/J8305 connected to the Finisher
Main PWB?
