[C] Buffer tray guide motor drive circuit
The buffer tray guide motor drive circuit controls the rotation and stoppage, rotational direction and
motor current of the buffer tray guide motor.
The buffer tray guide motor is driven by pulse signals (MOT2-OUT1A, MOT2-OUT1B, MOT2-OUT2A
and MOT2-OUT2B) output from the motor driver (IC48) under the command of a clock signal (TIOCA5),
a rotational direction signal (MOT2-DIR) and a current setting signals (MOT2-CUR1 and MOT2-CUR0)
from the CPU of the finisher control PC board, and thus this motor opens or closes the buffer tray guide.
