Standard Output Tray Full (Exit Full Stack Sensor) Troubleshooting Procedure
Step Actions and Questions
2
Test the Stack Full Sensor.
Run the Service Diagnostics Output Tray
Full test for the appropriate Exit.
Does the sensor state change when the
actuator is moved and sensor is
blocked?
3
Check the Stack Full Sensor connections.
For Exit 1:
Are P/J118, P/J613 and P/J432
connected?
For Exit 2:
Are P/J113, P/J606B and P/J434
connected?
4 Check continuity between the Stack Full
Sensor and the Exit PWB.
For Exit 1:
Is there continuity on each wire
between P/J118 <=> P/J432?
For Exit 2:
Is there continuity on each wire
between P/J113 <=> P/J434?
5 Check for +5 V to the Stack Full Sensor.
For Exit 1:
Is there +5 V across P/J118-3 (+) <=>
ground?
For Exit 2:
Is there +5 V across P/J113-3 (+) <=>
ground?
6 Check the Exit PWB connections.
Are P/J421 and P/J431 connected?
7 Check continuity between the Exit PWB
and Engine Logic Board.
1. Disconnect P/J431 and P/J421.
2. Check for continuity at the following:
P/J431-1 <=> P/J421-8
P/J431-2 <=> P/J421-7
P/J431-3 <=> P/J421-6
P/J431-4 <=> P/J421-5
P/J431-5 <=> P/J421-4
P/J431-6 <=> P/J421-3
P/J431-7 <=> P/J421-2
P/J431-8 <=> P/J421-1
Are these conductive?
8 Check for +5 V to the Exit PWB.
Is there +5 V across P/J421-3 (+) <=>
ground?
