Troubleshooting Procedure
Steps Actions and Questions
1 Check the chute assembly harness:
1. Disconnect P/J24 from the HVPS/engine
logic board.
2. Test for continuity across the following
points:
J24-14 <=> J245-5
J24-15 <=> J245-4
Are both continuous?
2 Check the tray 1 assembly harness:
1. Remove the registration clutch.
2. Disconnect P/J245.
3. Test for continuity across the following
points:
P/J245-9 <=> P/J243-2
P/J245-10 <=> P/J243-1
Are both continuous?
3 Measure the resistance of the registration
clutch between P/J243-1 <=> P/J243-2.
Does the resistance of the clutch measure
172 ohm +/-10% (at 20° C)?
4 Check the HVPS/engine logic board:
