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
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.

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.

Go to Flag 4 on BSD 12.11. Check the harness for an open circuit. If the
wire is good, replace the Finisher PWB

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.

If the problem continues, replace the Finisher PWB
Check the Eject Roll and Bearing
Check the following:
• Ensure that the Eject Motor Drive Belt
• Ensure that the Pulley is fastened to the Exit Roll shaft
• Check that the teeth in the Eject Motor pulley are clean and
