Abstract
An optical scanning system of a printer includes an optical scanning unit including a light source, a rotating polygonal mirror having a plurality of mirror surfaces for deflecting light emitted from the light source toward a photoreceptor web, and a driving source for driving the rotating polygonal mirror. The optical scanning system further includes a mirror, a photodetector installed to receive light scanned by the optical scanning unit to a position off the photoreceptor, and a controller for controlling a scanning start point of image data for lines by the optical scanning unit by obtaining information on addresses of mirror surfaces of the rotating polygonal mirror while counting the number of pulse signals output from the photodetector corresponding to the light received thereby, and by applying a line scanning synchronization correction time corresponding to the mirror surface address information with respect to a light receiving termination point of the pulse signal, to correct a line scanning synchronization time according to the difference in the amount of light reflected from each mirror surface of the rotating polygonal mirror.
