The power necessary for driving the printer is supplied by the main motor, the paper feed motor
and the scanner motor.
The main motor is controlled by the main motor drive signal (MDRIVE) output from the main
PCB, and the paper feed motor is controlled by the paper feed motor drive signal output from
the main PCB, and the scanner motor is controlled by the scanner motor drive signal (SDRIVE)
output from the main PCB.
