Circuitry Layout Block Diagram

When an original document is scanned, the data read by the CIS is converted from analog into
digital data on the AIC1 board, and then the digital data is sent to the ASC1 board.
The ASC1 board controls the connecting process of the data from the five CIS into main
scanning direction A0 width data. The now A0 width data is sent to the RIP controller.
The RIP controller then sends the data to the destination below depending on the function:
- For copy function
To the engine for printing
- For scan to file function
To the host computer over the network
The figure below shows the scanner's circuitry layout.
