Jam at G (Buffer Path Sensor Static) Troubleshooting Procedure (Continued)
Step Actions and Questions
8 Check for +5 V to the Buffer Path Sensor.
Is there +5 V across J8302A-15 <=>
J8302A-13 on the Finisher Main PWB?
9 Check Buffer Path Sensor signal.
Does the voltage across P8302A-14 <=>
P8302A-13 on the Finisher Main PWB
change when the actuator is operated?
10 Test the Registration Motor.
Run the Service Diagnostics Finisher
Registration Motor Test.
Does the motor rotate normally?
11 Test the Buffer Roller Drive.
Run the Service Diagnostics Finisher
Registration Motor CCW test.
Does the Buffer Roller rotate?
12 Print a Test Print.
Does the error still occur?
13 Check Main Drive harness connections.
Are P/J8335 and P/J8304 connected?
14
Print a Test Print.
Does the error still occur?
15 Check Main Drive Harness continuity.
1. Disconnect P/J8335 and P/J8304.
2. Check for continuity at the following:
P/J8335-1 <=> P/J8304-7
P/J8335-2 <=> P/J8304-8
P/J8335-3 <=> P/J8304-9
P/J8335-4 <=> P/J8304-11
P/J8335-5 <=> P/J8304-10
P/J8335-6 <=> P/J8304-13
Are these conductive?
16
Check Registration Motor resistance.
Is there some amount of resistance
across P8335-2/5(COM) and P8335-1/3/
4/6?
17
Check for +24 V to the Registration Motor.
Is there +24 V across J8304-8 <=>
ground and J8304-10 <=> ground on the
Finisher Main PWB?
18
Replace the Registration Motor.
Print a Test Print.
Does the error still occur?
