Troubleshooting Procedure
Steps Actions and Questions
Check the stacker detection signal (1):
1
1. Disconnect P/J70 on the stacker
PWBA.
2. Measure the voltage across J70-5
<=> J70-6 of stacker assembly
harness 2.
Does the voltage measure 3.3 VDC?
Check the stacker detection signal (2):
2
Measure the voltage across P/J30-4
<=> P/J30-3 on the HVPS/engine logic
board.
Does the voltage measure 3.3 VDC?
3 Check stacker assembly harness 2:
Remove stacker assembly harness 2.
Check for continuity between J70 <=>
J3070.
Is the harness continuous?
Check stacker assembly harness 1:
4
1. Remove stacker assembly harness
1.
2. Check for continuity between J30
<=> J3070.
Is the harness continuous?
5 Replace the stacker PWBA.
Does the problem still occur?
