Jam at F or Upper Tray (Exit Sensor OFF) Troubleshooting Procedure (Continued)
Step Actions and Questions
10 Test the Upper Tray Exit Sensor.
Run the Service Diagnostics Upper Tray
Exit Sensor test.
Does the sensor state change?
11 Check the Upper Tray Exit Sensor Harness
connections.
Are P/J8321 and P/J8312 on the sensor
harness, and P/J8312 and P/J8302 on
the Main Sensor Harness connected?
12 Print a Test Print.
Does the error still occur?
13 Check Exit Sensor Harness continuity.
1. Disconnect P/J8321 and P/J8312.
2. Check for continuity at the following:
P/J8321-3 <=> J8312B-1
P/J8321-2 <=> J8312B-2
P/J8321-1 <=> J8312B-3
Are these conductive?
14 Check Main Exit Sensor Harness
continuity.
1. Disconnect P/J8312 from the harness,
and P/J8302A on the Finisher Main
PWB.
2. Check for continuity at the following:
J8312A-3 <=> P/J8302A-7
J8312A-2 <=> P/J8302A-8
J8312A-1 <=> P/J8302A-9
Are these conductive?
15 Check for +5 V to the Upper Tray Exit
Sensor.
Is there +5 V across J8302A-9 <=>
J8302A-7 on the Finisher Main PWB?
16 Check the Upper Tray Exit Sensor signal.
Does the voltage across P8302A-8 <=>
P8302A-7 on the Finisher Main PWB
change when the sensor is actuated?
