[B] Paper pushing arm motor drive circuit
The paper pushing arm motor drive circuit controls the rotation and stoppage, rotational direction and
motor current of the paper pushing arm motor.
The paper pushing arm motor is driven by pulse signals (MT10-OUT1A, MT10-OUT1B, MT10-OUT2A
and MT10-OUT2B) output from the motor driver (IC49) under the command of a clock signal (TIOCC0),
a rotational direction signal (MOT10-DIR) and a current setting signals (MOT10-CUR1 and MOT10-
CUR0) from the CPU of the finisher control PC board, and thus this motor holds the paper with the
paper pushing plate.
