Laser Unit Operation (1)



The laser diode [1] emits a single laser beam.



A collimating lens [2] shapes the laser beam, which then passes
through the aperture [3] and cylindrical lens [4]. The aperture and
cylindrical lens focus the beam and aim it at the polygon mirror.



The polygon mirror [5] rotates clockwise at a very high but
constant speed.



When the laser beam strikes a face of the mirror, the mirror
surface reflects the beam across the photoconductor surface of
the drum after passing through more lenses and mirrors.
