[D] Front / rear alignment motor drive circuit

The front / rear alignment motor drive circuit controls the rotation and stoppage, rotational direction and motor current of the front alignment motor.

The front alignment motor is driven by pulse signals (MT5-OUT1A, MT5-OUT1B, MT5-OUT2A and MT5-OUT2B) output from the motor driver (IC45) under the command of a clock signal (TMO2), a rota- tional direction signal (MOT5-DIR) and a current setting signals (MOT5-CUR1 and MOT5-CUR0) from the CPU of the finisher control PC board, and thus this motor opens or closes the front alignment plate of the finishing tray.

The rear alignment motor is driven by pulse signals (MT6-OUT1A, MT6-OUT1B, MT6-OUT2A and MT6-OUT2B) output from the motor driver (IC41) under the command of a clock signal (TMO3), a rota- tional direction signal (MOT6-DIR) and a current setting signals (MOT6-CUR1 and MOT6-CUR0) from the CPU of the finisher control PC board, and thus this motor opens or closes the rear alignment plate of the finishing tray.
