Chapter 22-372.4.4 Controlling the Pickup Motor (M1) 0002-9497The following is a diagram of the circuit used to control the pickup motor (M1). The pickupmotor is a 4-phase stepping motor, and the circuit serves the following functions:- turning on/off the motor- controlling the rotation direction of the motor- controlling the rotation speed of the motorF-2-29IC9 on the ADF driver PCB receives print data (command) on printing mode from the hostmachine (magnification, operation mode, timing); in response, it generates drive pulses todrive the pickup motor.The pickup motor (M1) is a stepping motor, and its direction and speed of rotation arevaried by changing the order and the frequency of drive pulses (A, A*, B, B*).+24VAA*BB*M1J11MOT-B*MOT-B 341562IC9CPUMOT-A*MOT-AMOT-CUTMOT-REF1MOT-REF2+5VREFADF driver PCBIC8MotorDriver
