Laser Diode Unit: Generates laser beam
Collimator lens: Converts dispersed laser beams to straight beam
Cylindrical Lens: Concentrates sub-scanning directions of laser beam into one point
Polygon Motor:
Alters laser’s direction to main direction
#1, #2 F-theta lenses: Alters BEAM angle so that beams of same size are equally scanned
on the DRUM surface
