Duplexer motor control

The duplexer has one motor. The duplex feed motor reverses the output roller and the intermediate
output roller. Also, it drives the duplex reverse roller and the duplex re-pickup roller to feed the paper
and to drive the side misregistration sensor and the re-pickup roller.

Duplexer motor failure detection

The duplex controller does not determine if the duplex feed motor has failed; therefore, a jam occurs
when the motor fails.
