Abstract
A system and method for reducing scan line jitter caused by facet cut variation in scan systems employing a plurality of laser sources and a sensor for generating the timing for the laser sources. The system includes a controller for determining a unique time delay for each facet of the rotating mirror, and controlling the laser sources so that video provided by each laser source is delayed in a scan line by the unique time delay corresponding to the facet of the rotating mirror used in creating the scan line.
