Check the transport carrier motor connector J6. If
connected, check for approximately 30 volts on
pins 1 and 2 or at the wire connections located on
the rear of the transport carrier motor. If voltage is
incorrect, replace the system board. If voltage is
correct, check the motor for shorts.

on the system board.
•
A bind in the carrier transport
mechanism.
With the carrier transport motor cable (J6)
disconnected from the system board, check for 0
to 10 ohms between the following pins on the
motor:
J6-1 and J6-2
