Patent ID: 8115795

Claim:
An optical scanning device that projects an image onto a photoreceptor within a print system via overwriting, comprising: a laser light source that generates a plurality of light beam outputs, the light beam outputs are arranged in a two-dimensional parallelogram array within a substantially horizontal axis and a substantially vertical axis that is perpendicular to the horizontal axis, the two-dimensional parallelogram array has an odd number of rows of light beam outputs, wherein each row has an equal even number of light beam outputs; a rotating polygon mirror including a plurality of deflecting surfaces, each of the deflecting surfaces deflects the light beams emitted from the laser light source, wherein the light beam output array projects a first swath N onto the photoreceptor via the rotating mirror and swaths [N+1, N+2, . . . ] are each subsequently placed at a level one-half down the number of light beam outputs of the previous swath at an anchor point, each swath has the identical number of light emitting outputs as the two-dimensional array.
