Does the voltage measure 3.3 VDC?
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?
3
Check Stacker Assembly Harness 2:
Remove Stacker Assembly Harness 2.
Check for continuity between J70 <=>
J3070.
Is the harness continuous?
4
Check Stacker Assembly Harness 1:
