Scanner
The scanner uses a contact image sensor (CIS) unit which consists of an LED array illuminating
documents, a self-focus lens array collecting the reflected light, a CIS PCB carrying out
photoelectric conversion to output picture element data, and a cover glass on which a document
advances. When the document passes between the document pressure bar and the cover glass, it
is scanned.
