This fault is declared when either of the following occur:
•
The Stapler is not detected at the Front Corner position within 2000msec (1000ms if shift-
ing from Front Straight to Front Corner), after the Stapler Position Motor was energized to
move the Stapler to the front.
• The Stapler remains at the Front Corner position xxx msec after Stapler Position Motor
On
Initial Actions
Refer to BSD 12.12 for the following procedure.
Check the following:
• Obstructions in the Stapler Rail Assembly ( PL 18.18 ) that would prevent movement of the
Stapler
• Bent or out of position End Wall
• Bent or out of position Compiler Tray
• Clean the Stapler Front Corner Sensor
• Ensure that connectors P/J1043 and P/J1035 on the Finisher PWB, P/J1089 on the Sta-
pler Position Motor, and P/J1057 on the Stapler Front Corner Sensor and seated cor-
rectly and there are no obvious crimped or broken wires.
Procedure
Open the Stapler Cover. The Stapler is in the home position (at the front of the Fin-
isher).

NOTE: In the following step, dC330 [12-076] should move the Stapler toward the front of
the Finisher in small steps. Each time Start is pressed, the Stapler should move.
Cheat the Stapler Door Interlock Switch. Enter dC330 012-030 End Wall Motor Open.
Press
Start . Press Clear then enter 012-036 Compiler Tray Solenoid Down. Press Start .
Press Clear then enter 012-076 Staple Move Motor Top Front. Press Start . The Stapler
Position Motor moves the Stapler toward the front of the Finisher each time the
Start button is pressed.

Check the Stapler Drive Belt ( PL 18.17
), the Stapler Rail Belt ( PL 18.18 ), and Pulleys
to ensure they are in place and are not loose or broken. The Belts and Pulleys are
OK.
Y
N
Replace any defective components as required.
Remove the IOT Connector Cover ( REP 15.3.8
). +24 VDC is measured from P/
J1089 -2 to GND and from P/J1089 -5 to GND.
Y N
Go to Flag 11
on BSD 12.12. Check for an open circuit. If the problem contin-
ues, replace the Finisher PWB ( PL 18.4 ).
Go to Flag 10 on BSD 12.12. Check for an open circuit or a short circuit to GND. If
the wires are good, replace the Stapler Position Motor ( PL 18.17 ). If the problem
continues, replace the Finisher PWB ( PL 18.4 ).
Remove the Stapler Cover Assembly ( REP 15.3.3 ). Ensure that the Stapler is in the front
position and that the Stapler Front Corner Sensor is blocked (manually move the Stapler
toward the front if necessary). Enter dC330 012-269 Stapler Front Corner Sensor. Press
Start . The display indicates High.
Y N
Go to Flag 7 on BSD 12.12. Check the wire for a short circuit to GND. If the wire is
good, replace the Stapler Front Corner Sensor ( PL 18.18 ). If the problem continues,
replace the Finisher PWB ( PL 18.4 ).
Move the Stapler to the rear, to unblock the Stapler Front Corner Sensor. The display
changes to Low.
Y
N
Disconnect P/J1057
from the Stapler Front Corner Sensor. +5 VDC is measured
between J1057-1 and J1057-3.

Go to Flag 6
on BSD 12.12. Check the wires for an open circuit or a short circuit
to GND. If the wires are good, replace the Finisher PWB (PL 18.4).
Go to Flag 7 on BSD 12.12. Check the wire for an open circuit. If the wire is good,
replace the Stapler Front Corner Sensor ( PL 18.18 ). If the problem continues,
replace the Finisher PWB.
Perform the following:
•
Manually move the Stapler toward the front and rear of the Finisher to ensure that it
moves smoothly and that there are no obstructions in the Stapler travel. Correct any
problems found.
• Replace the Stapler Front Corner Sensor ( PL 18.18 ).
• If the problem continues, replace the Finisher PWB ( PL 18.4 ).
NOTE: In the following step, dC330 [12-078] should move the Stapler toward the rear of the
Finisher in small steps. Each time Start is pressed, the Stapler should move.
Remove the Stapler Cover Assembly ( REP 15.3.3 ). Cheat the Stapler Door Interlock Switch.
Enter dC330 012-030 End Wall Motor Open. Press Start . Press Clear then enter 012-036
Compiler Tray Solenoid Down. Press Start . Press Clear then enter 012-078 Staple Move
Motor Top Rear. Press Start . The Stapler Position Motor moves the Stapler toward the
rear of the Finisher each time the Start button is pressed.
