Reissue
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 ).
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 Sta-
pler Front Corner Sensor. Press
Start . The display indicates High.

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.

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 prob-
lems found.
• Replace the Stapler Front Corner Sensor ( PL 18.18 ).
• If the problem continues, replace the Finisher PWB ( PL 18.4 ).
12-246 RAP
This fault is caused by one of the following conditions:
•
During Initialization, the Control Logic does not detect the Stacker Offset Home Sensor in
the home position (High) within 500ms of the start of Offset Home recovery operation.
• During Set Eject, the Control Logic does not detect the Stacker Offset Home Sensor in
the offset position (Low) within 300ms from the start of the offset cycle.
• During Set Eject, the Control Logic does not detect the Stacker Offset Home Sensor in
the home position (High) within 300ms of the command to return to the home position.
Initial Actions
Refer to BSD 12.1 and BSD 12.14 for this procedure.
Procedure
Enter dC330 012-027 Eject Clamp/Offset Motor F/R. Press Start . The Eject Roll and Clamp
move to the offset position and back to home.
Y
N
Switch off the power. Remove the rear covers. Manually rotate the shaft of the Eject
Clamp/Offset Motor (
PL 18.21 ) clockwise. The shaft moves freely.
Y N
Disassemble the gear cluster ( PL 18.21
) connected to the Eject Clamp/Offset Motor.
Manually rotate the motor shaft The shaft moves freely.
Y N
Replace the Eject Clamp/Offset Motor ( PL 18.21
).
Check the following:
•
Check the gears for damage or dirt that may cause binding
• Check the Eject Roll ( PL 18.19 ) for damage or binding.
• Check the Pinch Roll/Compiler Cover/Set Separator area for binding ( PL
18.20 ).
• Ensure that the Offset Lever and Cam Follower ( PL 18.19 ) are correctly
installed, and that the Cam follower is positioned in the spiral groove in the Off-
set Cam (
PL 18.21 ).
The Eject Shaft moves front/rear as the motor shaft is rotated
Y
N
Check the following:
•
Check the gears for damage or dirt that may cause binding
• Check the Eject Roll ( PL 18.19 ) for damage or binding.
• Check the Pinch Roll/Compiler Cover/Set Separator area for binding ( PL
18.20 ).
• Ensure that the Offset Lever and Cam Follower ( PL 18.19 ) are correctly
installed, and that the Cam follower is positioned in the spiral groove in the Off-
set Cam (
PL 18.21 ).
Go to Flag 10 and Flag 11 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 Clamp/Offset Motor ( PL 18.21 ).
If the problem continues, replace the Finisher PWB ( PL 18.4 ).
