[J] Paddle motor drive circuit
The paddle motor drive circuit controls the rotation and stoppage, rotational direction and motor current
of the paddle motor.
The paddle motor is driven by pulse signals (MOT3-OUT1A, MOT3-OUT1B, MOT3-OUT2A and MOT3-
OUT2B) output from the motor driver (IC2) under the command of a clock signal (TIOCC3), a rotational
direction signal (MOT3-DIR) and a current setting signals (MOT3-CUR1 and MOT3-CUR0) from the
CPU of the finisher control PC board, and thus this motor rotates the paddle.
