2.9.1 Scanner System Overview

During the scanning process, the surface of a document is exposed to FR module light.
The light reflected from the paper is led through mirrors, a lens, and a slit to a CCD where optical-to-
electrical conversion is performed, converting the optical image data into an electrical (analog) signal.
This analog signal is changed to a digital signal, which then undergoes various corrective processes
necessary for image formation. After that, arithmetic operations are performed on the digital signal, which is
then transmitted to the data writing processor.
In this machine, a reduction-type CCD for color processing is used. CCD is arranged in 3 lines and covered
with color filters (Red, Green, and Blue).
