The Compiler Paper Sensor detects a sheet of paper present 250 ms. after Eject drive is initi-
ated.
Initial Actions
Refer to BSD 12.11 and BSD 12.14 for the following procedure.
Check for the following:
•
Obstructions in the Finisher paper path
• Obstructions in the Compiler Tray
• Ensure that connectors P/J1035 on the Finisher PWB and P/J1048 on the Compiler
Paper Sensor are seated correctly and there are no obvious crimped or broken wires.
Procedure
There is a sheet of paper in the Compiler Tray.
Y
N
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 circuit.
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 BSD 12.11. 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 sensor.
The actuator is binding.
Y N
Check for obvious damage, missing and/or broken Drive Motor gear assemblies, or
slipping drive rolls that would cause the copy to be slow to actuate the sensor.
Replace the Compiler Paper Sensor ( PL 18.16 ).
Enter dC330 012-024 Eject Motor Forward. Press Start . The Eject Roll is rotating.
Y N
The Eject Motor is rotating.
Y
N
Press Stop . Disconnect the Eject Motor Drive Belt. Press Start. The Eject Motor is
rotating.
Y
N
Go to Flag 8 and Flag 9 on BSD 12.14. Check the wires for an open circuit or a
short circuit to GND. If the wires are good, replace the Eject Motor ( PL 18.19 ).
If the problem continues, replace the Finisher PWB ( PL 18.4 ).
Check the Eject Roll and Bearing ( PL 18.19 ) for damage or contamination.
Check the following:
•
Ensure that the Eject Motor Drive Belt PL 18.19 is clean and undamaged.
• Ensure that the Pulley is fastened to the Exit Roll shaft ( PL 18.19 ).
• Check that the teeth in the Eject Motor pulley are clean and undamaged( PL 18.19 ).
Check the Eject Clamp Pinch Rolls ( PL 18.20 ) and Eject Roll PL 18.19 for glazing or contami-
nation.
