Two-dimensional ros emitter geometry with low banding sensitivity

An optical scanning device that projects an image onto a photoreceptor within a print system, 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 subsequently placed at a level one-half down the number of light beam outputs of the previous swath, wherein a seam is created when one swath is placed on another, row-to-row spacing error is not coincident with swath-to-swath seam error.
