Reverse Movement After a ScanAfter an image scan, the No. 1 mirror base is moved in reverse as far as the shading position at 234 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 325mm/sec for 100% magnification.[1][2]ReadercontrollerPCBInterfacePCB(forward)(reverse)Scanner motorLight-blocking plateNo.2 mirrorbaseScanninglampNo.1 mirror baseScannerHP sensorReader controller PCBMotordriverInterface PCB+24V/15VJ306AA*BB*CPU123465J308J307J202J203ScannermotorM501[1][1] Scanner motor control signal
