Chapter 55-9The following shows the components associated with the scanner drive system:F-5-15[1] Scanner Motor M501 Drive Signalstarts/stops the motor; controls the direction and speed of its rotation[2] Scanner HP Detection Signaldetects the presence of the No. 1 mirror base at home position5.3.1.2 Controlling the Scanner Motor 0010-7887iR7105 / iR7095The configuration of the system used to control the scanner motor is as follows; the motor driver on the interface PCB operates according to the signals from theCPU to start/stop the scanner motor and to control the direction and speed of its rotationF-5-16a. Reverse Movement After a ScanAfter an image scan, the No. 1 mirror base is moved in reverse as far as the shading position at 325 mm/sec regardless of the selected magnification.b. Forward Movement During a ScanDuring an image scan, the No. 1 mirror base is controlled at the speed indicated in the following figure; the No. 1 mirror base is moved forward at 325 mm/sec for100% magnification.F-5-17ERROR CODE:E202 (HP detection error)[1][2](forward)(reverse)Scanner motorLight-blocking plateNo.2 mirror baseNo.1 mirror baseReadercontrollerPCBInterfacePCBScanning lampScannerHP sensorReader controller PCBMotor driverInterface PCB+24V/15VJ306AA*BB*CPU123465J303J302J202J205Scanner motorM501[1][1] Scanner motor control signalStart positionAccelerationImage leading edgeConstant speedImage endDecelerationStopShift speedShift distance[1] [2] [3] [4][1] acceleration interval: accelerates to scanning speed.[2] run-up interval: servers as a margin to ensure stable speed[3] image read interval: reads the image at a specific speed[4] deceleration interval: decelerates at the end of the image and stops.HP
