12-180 RAP
The Compiler Entrance Sensor detects a sheet of paper present in standby or at initialization.
Initial Actions
Refer to BSD 12.1 and BSD 12.7 for the following procedure.
Check the Finisher Transport paper path for uncleared jams or obstructions. If no obstruction or
paper is found, continue with this RAP.
Procedure
Enter dC330 012-120 Compiler Entrance Sensor. Press Start . Manually actuate the Compiler
Entrance Sensor. The display changes from Low to High to Low as the actuator moves in
and out of the sensor.
Y
N
The display is always Low.

N
Disconnect P/J1052 . There is +5 VDC from J1052-1 to J1052-3.
Y N
+5 VDC is measured from
P/J1039 -1 to P/J1039 -3.
Y N
+5 VDC is measured from
P/J1026 -3 to P/J1026 -2.
Y N
Go to Flag 17 on BSD 12.1. Check the +5VDC wiring for an open cir-
cuit.
Replace the Finisher PWB ( PL 18.4 ).
Go to Flag 9 on BSD 12.7. Check the harness for an open circuit.
There is +5 VDC from J1052-2 to J1052-3.
Y
N
Go to Flag 10 on BSD 12.7. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB ( PL 18.4 )
Replace the Compiler Entrance Sensor ( PL 18.14 ). If the problem continues, replace
the Finisher PWB ( PL 18.4 ).
Disconnect P/J1052 . The display is High.
Y N
Go to Flag 10 on BSD12.7. Check the wire for a short circuit to GND. If the wire is
good, replace the Finisher PWB ( PL 18.4 )
Replace the Compiler Entrance Sensor ( PL 18.14 ).
Check the Compiler Entrance Sensor Actuator for binding as it moves in and out of the sensor.
12-181 RAP
The Compiler Paper Sensor detects a sheet of paper present at power up or at Job Complete.
Initial Actions
Refer to BSD 12.1 and BSD 12.11 for the following procedure.
Check the Compiler Tray for uncleared jams or obstructions. If no obstruction or paper is found,
continue with this RAP.
Procedure
Enter dC330 012-252 Compiler Paper Sensor. Press Start . Manually actuate the Compiler
Paper Sensor. The display changes from Low to High to Low as the actuator moves in
and out of the sensor.
Y
N
The display is always Low.
Y
N
Disconnect P/J1048 . There is +5 VDC from J1048-1 to J1048-3.
Y N
+5 VDC is measured from
P/J1035 -10 to P/J1035 -8.
Y N
+5 VDC is measured from
P/J1026 -3 to P/J1026 -2.
Y N
Go to Flag 17 on BSD 12.1. Check the +5VDC wiring for an open cir-
cuit.
Replace the Finisher PWB ( PL 18.4 ).
Go to Flag 3 on BSD 12.11. Check the harness for an open circuit.
There is +5 VDC from J1048-2 to J1048-3.
Y
N
Go to Flag 4 on BSD 12.11. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB ( PL 18.4 )
Replace the Compiler Paper Sensor ( PL 18.16 ). If the problem continues, replace
the Finisher PWB ( PL 18.4 ).
Disconnect P/J1048 . The display is High.
Y N
Go to Flag 4 on BSD12.11. Check the wire for a short circuit to GND. If the wire is
good, replace the Finisher PWB ( PL 18.4 )
Replace the Compiler Paper Sensor ( PL 18.16 ).
Check the actuator for the Compiler Paper Sensor for binding as it moves in and out of the sen-
sor. If the actuator is binding, replace the Compiler Paper Sensor (
PL 18.16 ).
