[PC Scan]
1. An analog image data is output from CISunit to IC503.
IC503 decode the analog data to digital data, and output to IC300.
Scanner I/F in IC300 process image data and store it in IC400
through SDRAM I/F. 
2. If necessary, the data is compressed via DSP. 
3. When you use the LAN, the data is output to PC 
through the LAN I/F and PHY(IC750). 
or
When you use the USB, the data is output to PC 
through the USB I/F.
