(2) Scanner (reading) section
This section performs the following functions.
In this section, an original is radiated by the lights from the scanner
lamp and the reflected lights are read by the CCD elements of three
lines (R,G,B) and converted into image signals. The image signals
are sent to the image process section (ICU PWB).

(4) Scanner (writing) section
There are four scanner (writing) units: yellow, magenta, cyan, and
black. Each scanner (writing) unit converts the dot image data of Y,
M, C, and K outputted from the ICU PWB into laser beams, and
scans to form latent electrostatic images on the OPC drum.
