1. An analog image data is output from CISunit to IC503.
IC503 decodes Analog 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 JBIG.
3. Print I/F retrieves the data from IC400 and outputs it to LSU.
