Original Scanning - Kyocera Mita KM-4530 Service Manual

2BC/D

(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 mirror 1 and 2 frame 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 DF is used, the mirror 1 and 2 frame
stop at the DF original scanning position to start scanning.
