Remove the Stacker Motor Belt. Enter dC330 012-040 Stacker Motor Up and press
Star
t. The Stacker Motor rotates.
YN
Go to F
lag 15 and F
lag 16 on BSD 12.15 Check for an open circuit or a short to
GND. If the wires are good, replace the Stacker Motor (PL 18.26) If the problem con-
tinues, replace the Finisher PWB (PL 18.4).
Ensu
re that the gears in the Stacker Motor Assembly are installed correctly, and are free
fro
m damage.
Ensure that the Front and Rear Stacker Tray Drive Belts are installed correctly (refer to
RE
P 15.2.
9).
The problem appears to be intermittent. Go to Flag
5, Flag 6, Flag 7, Flag 15, and Flag 16 on
BSD 12.15. Check the circuits of the Stacker Motor and the Stacker Lower Limit Sensor for a
loose connection or an intermittent short circuit to GND.

The Eject Clamp Sensor does not detect the Eject Clamp in the open position within 500msec
from the start of Eject Roll Up.
Initial Actions
Refer to BSD 12.1 and BSD 12.14 for the following procedure
Procedure
Enter dC330 012-026 Eject Clamp/Offset Motor Up/Down. Press Start. The Eject Clamp
opens and/or closes.
YN
Switch off the power. Remove the rear covers. Manually rotate the shaft of the Eject
Cla
mp
/Offset Motor (PL 18.21) counterclockwise. The shaft moves freely.
YN
Disassemble the gear cluster (P
L 18.21
) connected to the Eject Clamp/Offset Motor.
Manually rotate the motor shaft The shaft moves freely.
YN
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) f
or 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).
T
he Eject Clamp opens and/or closes as the motor shaft is rotated
YN
Check the following:
• Check the gears for damage or dirt that may cause binding
• Check the Eject Roll (PL 18.19) f
or damage or binding.
• Check the Pinch Roll/Compiler Cover/Set Separator area for binding (PL
18.20).
Go to Flag 10 and Fl
ag 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 F
inisher PWB (PL 18.4).
Remove the rear covers. Enter dC330 012-240 Eject Clamp Sensor. Press Star
t. Manually
rotate the shaft of the Eject Clamp/Offset Motor (PL 18.21) counterclockwise. The display
chang
es from High to Low as the motor shaft is rotated.
YN
The display is a constant Low.
YN
Disconnect P/
J1054. T
here is +5 VDC from J1054-1 to J1054-3.
