1. An analog image data is output from CIS unit to IC503.
IC503 decodes the analog data to digital data, and outputs to IC300.
Scanner I/F in IC300 processes image data and stores it in IC400
through SDRAM I/F.
2. If necessary, the data is compressed via DSP.
3. When using the LAN, the data is output to PC
through the LAN I/F and PHY(IC750).
or
When using the USB, the data is output to PC
CN59
through the USB I/F.

1.The print data is output from PC through LAN
and pass the PHY(IC750) and LAN I/F in IC300.
or
The print data is output from PC through USB
and pass the USB I/F in IC300.
then the data is stored in IC400 through SDRAM I/F.
2. Print I/F retrieves the data from IC400 and outputs it to LSU.
