At the actual printing, the laser beam scans across the rotating drum, the drum surface moves
42 micromillimeter when the laser beam completes one scanning operation and returns to a
position to be ready for next scanning. That is, the printing is done by the laser beam scanned
at this pitch (600 dpi).
Following shows an example of the laser beam raster scanning to form a character “A.”
