7.2 SCANNER UNIT (MP 501/601 ONLY)
The original image is illuminated by the exposure lamp and scanned by the CCD, the reflected
light being converted to an electrical signal.
If the ARDF is used, the scanner unit stops at the position of the ARDF exposure glass. Then the
machine sequentially scans each line of the image on the original in synchronization with the
movement of the original in the sub scan direction as it is fed by the ARDF.
