Door G Open (Door G Interlock Switch) Troubleshooting Procedure (Continued)
Step Actions and Questions
6 Check Door G Interlock Harness continuity.
1. Disconnect J8365 on the harness,
J8364 on the Eject Cover SW, and
J8388 and J8314 on the Finisher Main
PWB.
2. Check for continuity at the following:
J8365-1A <=> J8388-2
J8365-1B <=> J8364-2
J8365-2A <=> J8314-3
J8365-2B <=> J8314-2
J8364-1 <=> J8388-1
J8364-3 <=> J8314-1
Are these conductive?
7
Check +5/+24 V to the Door G Interlock
Switch.
Is there +5 V across J8314-2 <=> ground
on the Finisher Main PWB?
Is there +24 V across J8388-1 <=>
ground on the Finisher Main PWB?
8 Check the Door G Interlock Switch signal.
Does the voltage across J8314-2 <=>
J8314-3 on the Finisher Main PWB
change when the switch is pressed?
9
Check the Eject Cover Switch.
Does the voltage across J8365-1B <=>
ground on the Door G Interlock Harness
change when the Eject Cover Switch is
actuated?
10 Check the Door G Interlock signal.
Does the voltage across J8388-2 <=>
ground on the Finisher Main PWB
change when the Eject Cover SW and
Door G Interlock Switch are actuated
simultaneously?
11 Replace the Finisher Main PWB.
Cycle printer power.
