A raster output scanner is disclosed which utilizes a spot separation error correction system prior to its rotating polygon mirror. The spot separation error correction system of this invention is a zoom system which comprises two axially adjustable lenses. By moving the two lenses in a pre-determined relationship with each other, the magnification on the rotating polygon can be modified and as a result the spot separation on the photoreceptor can be substantially corrected. |
