Abstract
Methods and raster output scanner (ROS) systems are presented in which beam delay values are set for an array of ROS light sources based on wiper error and jitter error with column alignment achieved at an alignment location spaced from a center of scan (COS) location toward an end of scan location (EOS) along a fast scan range of operation of the ROS.
