Chapter 22-36F-2-342.5.3 Controlling the Delivery Reversal Motor (M3) 0002-9898The following is a diagram of the circuit used to control the delivery reversal motor (M3). The delivery reversalmotor (M3) is a 4-phase stepping motor, and the circuit has the following functions:- turning off/on the motor- controlling the rotation direction of the motor- controlling the rotation speed of the motorF-2-35The CPU (IC4) on the ADF driver PCB receives data (command) from the host machine on print mode(magnification, operation mode, timing); in response, it generates drive pulses to drive the delivery reversal motor(M3). The delivery reversal motor (M3) is a stepping motor, and the direction and speed of rotation are changed bychanging the order and frequency of drive pulses (A, A*, B, B*).:Motor reversal rotationArchingNormal rotation Reversal rotationPickup/feed Reading ReversalPickup clutch(CL1)Separation rearsensor (PI7)Registration sensor(PI1)Read sensor(PI8)Delivery reversalsensor (PI9)Pickup motor(M1)Feed motor(M2)Delivery reversalmotor (M3)Locking motor(M4)Original placementsensor (PI5)Release solenoid(SL2)ArchingImage leading edgesensorReversal standingStart key ONIC1MotorDriver+24VAA*BB*M3J10B*A*A783654REF1IC9CPUBADF driver PCBREF2REF+5V
