Jam at F (Transport Gate Sensor ON) Troubleshooting Procedure (Continued)
Step Actions and Questions
9
Test the X'port Entrance Sensor.
Run the Service Diagnostics Transport
Entrance Sensor test.
Does the sensor change state when the
sensor is blocked?
10 Check harness connections.
Are P/J8319 and P/J8303 on the
Entrance Sensor Harness and P/J8302A
on the Main Sensor Harness
connected?
11 Print a Test Print.
Does the error still occur?
12 Check X'port Entrance Sensor Harness
continuity.
1. Disconnect P/J8319 and P/J8303.
2. Check for continuity at the following:
P/J8319-3 <=> J8303B-1
P/J8319-2 <=> J8303B-2
P/J8319-1 <=> J8303B-3
Are these conductive?
13 Check Main X'port Entrance Sensor
Harness continuity.
1. Disconnect P/J8303 on the harness, and
P/J8302A on the Finisher Main PWB.
2. Check for continuity at the following:
J8303A-3 <=> P/J8302A-1
J8303A-2 <=> P/J8302A-2
J8303A-1 <=> P/J8302A-3
Are these conductive?
14 Check for +5 V to X'port Entrance Sensor.
Is there +5 V across J8302A-3 <=>
J8302A-1 on the Finisher Main PWB?
15 Check the X'port Entrance Sensor signal.
Does the voltage across P8302A-2 <=>
P8302A-1 on the Finisher Main PWB
change, when the sensor is blocked?
16 Check the Finisher Transport Motor.
Run the Service Diagnostics Finisher
Transport Motor Test.
Does the motor rotate normally?
