Abstract

Slow scan registration is required in a color printing system to insure that different color images forming a composite print are properly aligned. In the printing system image registration problems may result when the polygon rotation of the raster output scanner (ROS) is not synchronous with the photoreceptor belt or drum speed. Image registration errors occur when the different color images forming the composite image are placed on top of each other as the photoreceptor (PR) belt or drum moves in relation to the polygon of the ROS.
