[G] Exit motor drive circuit

The exit motor drive circuit controls the rotation and stoppage, rotational direction and motor current of the exit motor.

The exit motor is driven by pulse signals (MT11-OUT1A, MT11-OUT1B, MT11-OUT2A and MT11- OUT2B) output from the motor driver (IC44) under the command of a clock signal (TIOCA2), a rota- tional direction signal (MOT11-DIR) and current setting signals (MOT11-CUR1 and MOT11-CUR0) from the CPU of the finisher control PC board, and thus this motor rotates the stationary tray roller and exit roller.
