The CPU (IC1) of the ADF controller PCB receives commands from the host machine for
print mode (e.g., magnification, operation, timing). In response, it sends drive pulses to the
pickup motor.
The pickup motor is a stepping motor, and changes the order and frequency of its drive
pulses (OUTA, OUTA*, OUTB, OUTB*) to change the direction and speed of motor
rotation.
