Abstract: An apparatus includes an output voltage sensing unit, which senses an output voltage of a laser diode, which has been sampled during a power control period and transmits the sensed output voltage of the laser diode to an output voltage control unit; the output voltage control unit, which obtains an error voltage between a reference voltage and the sensed output voltage of the laser diode and generates a control voltage by proportionally integrating the error voltage; and an optical power compensation unit, which receives the control voltage and generates a compensated control voltage by compensating for an optical power deviation on the photosensitive drum during the printing period.

Abstract: A scanner motor assembly has a scanner motor for rotating a polygon mirror, a frame with a plurality of supporting members supporting the scanner motor, a plurality of anti-vibration members interposed between the scanner motor and the frame, and a plurality of fasteners that fix the scanner motor to the frame motor. With this construction, the scanner motor can be retained parallel to the frame because it is laid on the supporting members mounted on the frame, the anti-vibration members interposed between the scanner motor and the frame can reduce vibration, and thus noise generated due to the vibration can be suppressed.
