Figure 5.1 Theory of Operation
The reflected rays of the your original as shown in the above Figure 5.1 pass through the lens and
creates an image on the CCD (Charged Coupled Device). Then, according to the different light intensity
perceived by the CCD, the CCD will transfer these data into a series of analog signals to the main
board, where the signals are turned into digital signals. These digital signals flows to the image
processor to store into a printer acceptable format then goes to 1284 Controller to transfer to printer or to
a host computer.
