2.3.1 Introduction
Figure 2.1 Theory of Operation
The reflected rays of 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
flow to the image processor and store into the CPU (Central Processing Unit). Through the
commands from the Control Panel, the digital signals may go to USB host (copy port) to send
copy command to printer, or to RJ-45 to send filing command to FTP/HTTP server or to send
email command to SMTP server, or to USB device (USB port) to PC for scan, or receive print
command from PC via USB device (USB port for print).
