8. Scanner Motor (M3) Control Circuita. OutlineFigure 3-308 shows the circuit used to control the scanner motor, and the circuit hasthe following functions.q Turning on and off the scanner motor.w Controlling the direction of rotation of the scanner motor.e Controlling the speed of rotation of the scanner motor.b. Stopping the Rotation of the MotorWhen the scanner motor drive control signal (M3ON) goes ‘0’, the drive circuit turnsoff so that the motor does not rotate.c. Moving the Scanner ForwardWhen the scanner motor drive control signal (M3ON) goes ‘1’ and the scanner for-ward signal (M3F/R) goes ‘0’, the drive circuit turns on so that the scanner motor rotatesclockwise, thereby moving the scanner forward.Figure 3-308Scannermotor (M3)RotorHallICUWSCMCLKVScanner motor driver PCBDC controllerPCBMotor stopcircuitMotordrivecircuitMotor rotationspeedcontrol circuitJ632-8J112-B5J632-6J112-B7J632-7J112-B6J632-9J112-B4-5-B8-4-B9-3-B10-1J632-2J112-B11M3BRK*M3F/R*M3ON*M3CLM3MD2M3MD1M3MD0M3FSM3FGJ112-B12ClockpulsegeneratorCHAPTER 3 EXPOSURE SYSTEM3-17COPYRIGHT © 1997 CANON INC.
