The DC controller signals the lasers to emit light, and the laser beams pass through lenses and onto the scanner mirror, which rotates at a constant speed. The mirror reflects the beam onto the photosensitive drum inside of the toner cartridge in the pattern required for the image, exposing the su**ce of the drum so that it can receive toner.
