[I] Transport motor drive circuit
The transport motor drive circuit controls the rotation and stoppage, rotational direction and motor cur-
rent of the transport motor.
The transport motor is driven by pulse signals (MOT7-OUT1A, MOT7-OUT1B, MOT7-OUT2A and
MOT7-OUT2B) output from the motor driver (IC43) under the command of a clock signal (TIOCA0), a
rotational direction signal (MOT7-DIR) and current setting signals (MOT7-CUR1 and MOT7-CUR0)
from the CPU of the finisher control PC board, and thus this motor rotates the stack transport roller-1
and -2.
