Phaser 6130 Color Laser Printer Service Manual

Four laser diodes (one for each color) in the Laser Unit emit laser beams. The

beams are directed by mirrors to the rotating polygon mirror attached to the

scanner motor. As the polygon mirror rotates, the beams are directed through

a series of lenses and mirrors to each of the drums, which are scanned by the

beams from end to end in the axial direction.
