General Description

In the scanning section, this equipment uses a CIS (Contact Image Sensor) for scanning the image.
The surface of an original is irradiated with light from the LED array mounted on the CIS unit and the
reflected light is scanned by the CCD where the optical image data are converted into an analog electri-
cal signal, and then transmitted to the MAIN board. After the binarization and the various image pro-
cessing operations necessary for image formation are performed on the MAIN board, the data are
transmitted to the writing section.
