• The following detail the image processing operations performed by the scanner section.
1. A reduction type CCD sensor is used to read the light reflected off the original and
convert the optical data to a corresponding electric signal. To make data process-
ing faster, data transfer and output are done through two channels, one for even-
numbered pixels and the other for odd-numbered pixels.
2. The odd and even analog signals output from the CCD sensor chips are synthe-
sized to form a single string of signal data which is in turn converted to 10-bit digital
signals (1024 gradation levels).
• The image data is transmitted to MFP board on the write section through the interface
cable.
