4.3.6 Mirror Scan Motor (M1) Control Circuit

Drive of the Scanning Motor (M1) is controlled by the signals which are input to the Motor Driver Board (PWB-T) from the Main Control Board (PWB-BB).

These signals determine the direction (forward or backward) and speed of rotation of the Scanning Motor when the Scan Mirror makes a prescan and scan motion.

These signals cause the Scanning Motor drive pulses to be output from the pins (A, B, A, B) of the Motor Driver Board (PWB-T), which turns the Scanning Motor (M1).
