[H] Stapler unit shift motor drive circuit
The stapler unit shift motor drive circuit controls the rotation and stoppage, rotational direction and
motor current of the stapler unit shift motor.
The stapler unit shift motor is driven by pulse signals (MOT9-OUT1A, MOT9-OUT1B, MOT9-OUT2A
and MOT9-OUT2B) output from the motor driver (IC42) under the command of a clock signal (TIOCA3),
a rotational direction signal (MOT9-DIR) and a current setting signals (MOT9-CUR1 and MOT9-CUR0)
from the CPU of the finisher control PC board, and thus this motor shifts the stapler unit back and forth.
