Remove the Stacker Motor Belt. Enter dC330012-041 Stacker Motor Down and press
Start. The Stacker Motor rotates.
Y N
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
tinues, replace the Finisher PWB
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
BSD 12.15. Check the circuits of the Stacker Motor and the Stacker Upper Limit Sensor for a
loose connection or an intermittent short circuit to GND.
