Then, according to the different lightintensity perceived by the CCD, the CCD will transfer these data into a series of analog signalsto the main board, where the signals are turned into digital signals. These digital signalsflow to the image processor and store into the CPU (Central Processing Unit). Through thecommands from the Control Panel, the digital signals may go to USB host (copy port) to sendcopy command to printer, or to RJ-45 to send filing command to FTP/HTTP server or to sendemail command to SMTP server, or to USB device (USB port) to PC for scan, or receive printcommand from PC via USB device (USB port for print).MaiBoardColdFluorescentLenCCDAnaloguSignalDigital SignalImagProcessorReflecteRayCPUScanPrintPrintFilingE-mailCopyControlPanelCPUUSB DeviceControllerRJ-45EthernetUSB HostPCFTP HTTP ServerSMTP ServerPrinter
