2.1.2 Flat Bed Scannser (FBS) section
The FBS (Flat Bed Scanner) section consists of document glass (pane), optical reading section, scan-
ner frame Assy, and scanner driving section.
A lamp (White light LED array) is on the scanner frame, and the light reflected from the document
passes through four mirrors and a lends to form a reduced image on CCD sensor as the scanner
motor moves the scanner. The CCD sensor converts the light pattern (image data) into an electrical
image signal.
Scanner frame Moving Mechanism
During scanning, the scanner frame projects an even amount of light from the exposure lamp onto the
entire surface of the document. The light is reflected from the original to the mirror through the lens to
the CCD. The scanner frame is driven by the FBS motor and scanner drive belts.
The scanner frame driving speed is determined by zoom ratio in reference to the full size mode. It is
at home position where ADF scanning begins. The home sensor watches this position.
