12-240 RAP
The Control Logic does not detect one of the following conditions:
• End Wall Open (H) +5 VDC, from the End Wall Open Sensor, within 300msec after the
signal, End Wall Motor Open.
• End Wall Open (L) +5 VDC, from the End Wall Open Sensor, within 300msec after the sig-
nal, End Wall Motor Close.
Initial Actions
Refer to BSD 12.1, BSD 12.11, and BSD 12.12 for the following procedure.
Procedure
NOTE: The output of the End Wall Open Sensor is Low when the sensor is blocked, and High
when the sensor is not blocked.
Open the Stapler Door and cheat the interlock. Enter dC330 012-270 End Wall Open Sensor.
Press Start.
Block and unblock the End Wall Open Sensor with a piece of paper. The
from High to Low to High as the paper moves in and out of the sensor.
Y N
The display is always Low.
Y N
Disconnect P/J1046. There is +5 VDC from J1046-1 to J1046-3.
Y N
+5 VDC is measured from P/J1035-12 to P/J1035-13.
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 8 on BSD 12.12. Check the harness for an open circuit.
There is +5 VDC from J1046-2 to J1046-3.
Y N
Go to Flag 9 on BSD 12.12. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB
Replace the End Wall Open Sensor
Finisher PWB (PL 18.4).
Disconnect P/J1046. The display is High.
Y N
Go to Flag 9 on BSD12.12. Check the wire for a short circuit to GND. If the wire is
good, replace the Finisher PWB

Press Stop. Press the C button. Enter dC330 012-036 Compiler Tray Solenoid Down. Press
Start. The Compiler Tray Solenoid energizes.
Y N
The solenoid is always in the energized position.
Y N
Press Stop. There is + 24 VDC from P/J1041-2 to GND.

Go to Flag 7
the circuit is good, replace the Compiler Tray Solenoid
Press Start. There is less than 1.0 VDC from P/J1041-2 to GND.
Y N
Replace the Finisher PWB.
Check the alignment of the solenoid. Check for binding of the linkage. If the checks
are good, replace the Compiler Tray Solenoid
changes
Disconnect P/J1082. The solenoid deenergizes.
Y N
Replace the Compiler Tray Solenoid
Go to Flag 8 on BSD 12.11. Check the harness for a short circuit. If the circuit is good,
replace the Finisher PWB
Press Stop. Press the C button. Enter dC330 012-030 End Wall Motor Open. Press Start.
The End Wall moves to the open position.
Y N
The End Wall can be manually moved to the open position.
Y N
Check for binding of the linkage, or damage to the End Wall.
Connect the DMM between P/J1083-1 (+) and P/J1083-2 (-). set the meter for negative
Peak Hold. Press Start. A pulse of -20 VDC or greater is recorded.
Y N
Go to Flag 12 and

Press the C button. Enter dC330 012-031 End Wall Motor Close. Press Start. The End Wall
moves to the closed position.
Y N
Replace the Finisher PWB
