Chapter 22-382.6.2 Sequence of Operation 0002-9872Sequence of Operation (small-size, delivery)F-2-382.6.3 Controlling the Feed Motor 0002-9874The following is a diagram of the circuit used to control the feed motor (M2). The feed motor (M2) is a 4-phasestepping motor, and the circuit has the following functions:- turning on/off the motor- changing the rotation direction of the motor- changing the rotation speed of the motorF-2-39The CPU (IC9) on the ADF driver PCB receives data (command) from the host machine on printing mode(magnification, operation mode, timing); in response, it generates drive pulses to drive the feed motor (M2). The feedmotor (M2) is a stepping motor, and its direction and speed of rotation are changed by changing the order of drivepulses (A, A*, B, B*).Start key ONOriginal placementsensor (PI5)Pickup/Feed ReadingPickup clutch(CL1)Separation rearsensor (PI7)Read sensor(PI8)Delivery reversalsensor (PI9)Pickup motor(M1)Feed motor(M2)Delivery reversalmotor (M3)Locking motor(M4)Registration sensor(PI1):Motor reversal rotationPressure solenoid(SL2)Image leading edgesignalArchingReversal rotation Normal rotationDeliveryREF2IC4MotorDriver+24VM2J8MODECLKRESET 341562CUTIC9CPUADF driver PCBREF1+5VA*B*BAREF
