Go to Flag 15
and Flag 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 ).
Ensure that the gears in the Stacker Motor Assembly are installed correctly, and are free
from damage.
Ensure that the Front and Rear Stacker Tray Drive Belts are installed correctly (refer to
REP 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.

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
