Abstract

Document processing systems and duplex printing methods are presented in which side 1 to side 2 image on paper (IOP) magnification errors are mitigated by use different speeds for raster output scanner (ROS) for scanning images for different final print sides, and by selective use of electronic registration adjustment by adding or removing sub-pixels from the image data to compensate for ROS speed change overshoot or undershoot.
