Check the gears and pulleys.
Check the following parts for wear, glazing, or slipping:
• Lower Exit Chute (PL 18.14)
• Exit Roll (PL 18.14)
• Exit Roll Belt (PL 18.14)
• Compiler Drive Belt (PL 18.9)
NOTE: The output of the Compiler Enter Sensor is Low when the sensor is blocked, and High
when the sensor is not blocked. Paper on the sensor moves the actuator away from the sen-
sor, unblocking it.
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.
Y 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
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

Check the actuator for the Compiler Entrance Sensor for binding as it moves in and out of the
sensor. The actuator is binding.

Check for obvious damage, missing and/or broken Drive Motor gear assemblies and drive
belts that would cause the copy to be slow to actuate the sensor.
