Remove the Stacker Motor Belt. Enter dC330012-041 Stacker Motor Down 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
3, Flag 4, Flag 7, Flag 15, and Flag 16 on
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.
12-256 RAP
The Stacker Lower Limit Sensor detects the Stacker Tray at the lower limit during ascension, or
does not detect a change of state during ascension.
Initial Actions

YN
+5 VDC is measured from P
/J1026
-3 to P/J1026-2.
YN
Go to F
lag 17 on BSD 12.1. Check the +5VDC wiring for an
open circuit.

cuit.
There is +5 VDC from J1066-2 to J1066-3.
YN
Go to Fl
ag 6 on BS
D 12.15. Check the harness for an open circuit. If the
wire is good, replace the Finisher PWB (PL 18.4)
Replace the Stacker Upper Limit Sensor (PL 18.27
). If the problem continues,
replace the Finisher PWB (PL 18.4).
Disconnect P/J1066. Th
e display is High.
YN
Go to F
lag 6 and Flag 7 on BSD12.15. Check the wire for a short circuit to
