Scanner Assy.

This assembly consists of LED Light-Guide, Lens, and Contact Image Sensors. A light through the
LED Light-Guide is reflected from the screen film surface.
Then the reflected light will reach the Contact Image Sensors (CISs) through the Lens.
These CISs will convert the light into electrical signals, and then will transmit the signals
to the SCANNER Board.
Then the SCANNER Board will convert the signals into image digital signals and then will transmit
the digital signals to the CONTROL Board.
Then the CONTROL Board will store them in its inner memories so that they can be downloaded to
a USB Flash Memory and a SD Card, or can be printed out with a printer.
