(1) Original scanning
The original image is illuminated by the exposure lamp (EL) and scanned by the CCD in the CCD PWB (CCDPWB) via the
three mirrors and lens, the reflected light being converted to an electrical signal.
The mirror 1 and 2 frames travel to scan on the optical rails on the front and rear of the machine to scan from side to side.
The speed of the mirror 2 frame is half the speed of the mirror 1 frame.
When the DP is used, the mirror 1 and 2 frames stop at the DP original scanning position to start scanning the first side of
the original. The DP scans 2 sides of the original at the same time by using CIS to scan the second side of the original.
