AR-BC260 DESCRIPTIONS OF EACH SECTION 7 - 22
4. Optical section (Scanner section)
A. Operational descriptions
(1) Outline
This section functions and operates as follows:
1) The copy lamp radiates light onto the document, and the
reflected light is scanned by the three line (RGB) CCD ele-
ment and then converted into image signals (analog).
2) The image signals (analog) are converted into 8bit digital sig-
nals by the A/D converter.
3) The image signals (digital) are sent to the image process sec-
tion (ICU PWB).
