1.2 Main Drive
The power necessary for driving the printer is supplied by the main motor, the paper feed
motor and the laser unit 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 laser unit motor is controlled by the laser unit motor
drive signal (SDRIVE) output from the main PCB.
