Chapter 22-382.4.5 Controlling the Lock Motor (M4) 0003-6080The following is a diagram of the circuit used to control the lock motor, and the circuit hasthe following function:- turning on/off the motor- controlling the speed of motor rotationF-2-30IC9 on the ADF driver PCB receives data (command) from the host machine on printingmode (magnification, operation mode, timing); in response, it generates drive pulses todrive the lock motor.The lock motor (M4) is a stepping motor, and the direction and speed of its rotation arechanged by changing the order and frequency of drive pulses (A, A*, B, B*).IC2MotorDriverAA*BB*M4J9MOT-AMOT-B3654MOT-REFIC9CPUMOT-CUTADF driver PCBMOT-REF+5V3REF
