The charged surface of the drum is exposed to the laser beam scanning from the laser scanner unit.
Figure 2-1-10 Exposure
The polygon motor (with polygon mirrors) revolves (27,165 rpm) to reflect the laser beam over the drum. Lenses and
diversion mirror are housed in the laser scanner unit. These lenses adjust the diameter of the laser beam (670 nm
wavelength) so that the laser beam effectively focalizes on the drum surface.
