Abstract
In a raster scanning system (ROS) of a multi-station xerographic printing device, the image height of each of the images formed from a plurality of clustered laser beams having dissimilar wavelengths is changed so that the image heights approximate each other. This is accomplished by passing one or more of the light beams through light transmissive plates having a predetermined thickness and index of refraction. The light transmissive plates can be optical filters that also one used to separate the clustered light beams based upon their wavelength and/or polarization.
