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).
