ABSTRACT:
In a method and apparatus for raster scanning optical output device, such as a laser printer or the like, an array of independently addressable light emitting devices, such as an array of solid state lasers, is used to control spot position on an image plane in the slow scan direction. The array is disposed such that the spots emitted from each element of the array impinge the image plane displaced in the slow scan direction from one another. The total distance between all the spots is less than the distance between fast scan direction scan lines. Only a single element of the array is operated per scan line, thus only a single spot is formed on the image plane per scan line. Control of which of the elements of the array emits a light beam per scan line allows control of the spot position in the slow scan direction for that scan line.
