Static Jam at F (Transport Entrance Sensor) Troubleshooting Procedure (Continued)
Step Actions and Questions
7 Check Entrance Sensor signal.
Does the voltage across P8302A-2 <=>
P8302A-1 on the Finisher Main PWB
change when the sensor is blocked?
8 Check the Transport Motor.
Run the Service Diagnostics Transport
Motor test.
Does the motor rotate normally?
9 Test Entrance Roller drive.
Run the Service Diagnostics Transport
Motor test.
Do the Entrance Rollers rotate?
10 Check Main Drive Harness connections.
Are P/J8342 and P/J8304 connected?
11 Print a Test Print.
Does the error still occur?
12 Check Main Drive Harness continuity.
1. Disconnect P/J8342 and P/J8304.
2. Check for continuity at the following:
J8342-1 <=> J8304-23
J8342-2 <=> J8304-16
J8342-3 <=> J8304-25
J8342-4 <=> J8304-27
J8342-5 <=> J8304-18
J8342-6 <=> J8304-29
Are these conductive?
13 Check Transport Motor resistance.
Is there some amount of resistance
across P8342-2/5(COM) and P8342-1/3/
4/6?
14 Check for +24 V to the Transport Motor.
Is there +24 V across J8304-16 <=>
ground, and J8304-18 <=> ground on
the Finisher Main PWB?
15 Replace the Transport Motor.
Print a Test Print.
Does the error still occur?
