D. Scanner Motor
1. Outline
The scanner motor (M2) is a stepping motor, and the motor is controller by the DC controller PCB.
The CPU on the DC controller PCB sends to the motor controller PCB through the I/O circuit such com-
mands as clockwise rotation (moving the scanner forward), counterclockwise rotation (moving the scanner
in reverse), and rotation speed.
The motor controller circuit operates according to the instructions of the CPU and sends pulse signals
to the power control circuit. The power control circuit, in turn, supplies power to the scanner motor (M2)
according to such pulse signals, thereby rotating the scanner motor (M2).
