Original Scanning - Kyocera KM-1620 Service Manual

(1) Original scanning

The original image is illuminated by the exposure lamp (EL) and scanned by the CCD PCB (CCDPCB) in the image
scanning unit via the three mirrors, the reflected light being converted to an electrical signal.
The scanner and mirror 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 frames is half the speed of the scanner. When the DP is used, the scanner and mirror
frames stop at the DP original scanning position to start scanning.
