8-117 Tray 3 Feed Out Sensor On RAP
The Tray 3 Feed Out Sensor detected paper when closing the Front Cover or when power was
switched on.
Initial Actions
• Refer to BSD 8.3 and BSD 8.10 for the following procedure.
• Check for any obstructions in the paper path.
Procedure
Enter dC330 008-115 Tray 3 feed out Sensor. Press Start. The display indicates L.
YN
Go to Fl
ag 3 and Fla
g 4 on BSD 8.3 and check the harness for an open circuit. If the har-
ness is good, replace the Tray 3 Feed Out Sensor (PL 2.
8).
If the fault code is present and can not be cleared, replace the Tray PWB (PL 9.
3). If the fault
code is not present and is occurring intermittently, go to Flag 3 on BSD 8.3 and check the har-
ness for an intermittent short circuit. If the harnes
s is OK
, ensure that the sensor actuator
moves freely. If the actuator is OK, replace the Tray 3 Feed Out Sensor (PL 2.8). If the problem
continues, replace the Tray PWB (PL 9.3).

Procedure
Cheat the L/H Cover Interlock Switch. Enter dC330 008-119 Tray 4 Pre feed Sensor. Press
Start. Block the Tray 4 Prefeed Sensor with a sheet of paper. The display changes from H
to L.
YN
T
he display indicates a constant H.
YN
Go to F
lag 1 on B
SD 8.4 and check the harness for a short circuit. If the harness is
good, replace the Tray 4 Prefeed Sensor (PL 2.5).
Connect the meter from P/J4
15A-8 on the IOT Drive PWB to machine frame. Block the
Tray 4 Prefeed Sensor with a sheet of paper. The voltage at P/J415A-8 go
es from +5
VDC when the sensor is not blocked, to less than +1.0 VDC when the sensor is
blocked.
YN
There is +5 VDC between P
/J804-
5 and P/J804-3 on the Tray PWB.
YN
Go to F
lag 2 on BS
D 8.4 and check the harness for a short circuit. If the har-
ness is good, replace the Tray PWB (PL 9.3).
G
o to Flag 1 and Flag 2 on BSD 8.4 and check the harness for an open circuit. If the
harness is O
K, replace the Tray 4 Prefeed Sensor (PL 2.5). If the problem continues,
