As a scanning device, this product adopts color CIS (Contact Image Sensor) for each scanning side independently.
The color CIS has Red, Green, and Blue LEDs. Changing the three colors enables it to scan color data.
Scanned data (Analogue) from the color CIS is transmitted to CONTROL Board via RELAY (FRONT) Board and RELAY (BACK)
Board.
