Troubleshooting Procedure
Steps Actions and Questions Yes No
1
Check the Stacker detection signal (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?
Go to step 5. Go to step 2.
2
Check the Stacker detection signal (2):
Measure the voltage across P/J30-4 <=>
P/J30-3 on the HVPS/Engine Logic Board.
Does the voltage measure 3.3 VDC?
Go to step 3. Replace the
HVPS/Engine
Logic Board
(page 8-89).
3
Check Stacker Assembly Harness 2:
Remove Stacker Assembly Harness 2.
Check for continuity between J70 <=>
J3070.
Is the harness continuous?
Go to step 4. Replace Stacker
Assembly
Harness 2.
4
Check Stacker Assembly Harness 1:
1. Remove Stacker Assembly Harness 1.
2. Check for continuity between J30 <=>
J3070.
Is the harness continuous?
Go to step 5. Replace Stacker
Assembly
Harness 1.
5
Replace the Stacker PWBA.
Does the problem still occur?
Replace the
HVPS/Engine
Logic Board
(page 8-89).
Problem solved.
