ABSTRACT:
A method and apparatus for producing within an imaging area of a charged surface and without significant banding, an array of pixel spots forming image scan lines including a start-of-image scan line. The method and apparatus include a ROS for generating an even number of light beams. The ROS includes a rotating polygon assembly having a plural number of facets `F` for each deflecting the even number of light beams onto the imaging area of the charged surface forming scanning beams for simultaneously each producing an image scan line. The method and apparatus also include a controller for controlling the even number of light beams so that a scanning beam spacing "d" is maintained where "d" is equal to `F`-1, and so that at start-of-producing the pixel spots forming the image scan lines, the beams are offset relative to the start-of-image scan line and only one-half the even number of light beams is deflected onto the imaging area of the charged surface to each form an image scan line.
