The CCD generates an analog video signal from the light reflected from the
original.
The scanned data passes to the scanner control board (SCB). The SCB converts
scanned video data from the analog signal to a digital signal. Then the data passes
to the control board. The control board does digital video data processing, such as
halftone (dither/error diffusion), reduction/enlargement, and smoothing. Then it
stores the processed data in the page memory. The processed data passes to the
mechanical control board (MCB). The MCB drives the laser diode based on the
processed data signal. Then, the laser beam writes a latent image on the drum.
