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.

Abstract: A scanning system for use in an imaging apparatus includes a mirror assembly having a rotating mirror with a plurality of facets, a motor operatively coupled to the rotating mirror and closed loop control circuitry coupled to the motor. The mirror assembly generates a lock signal indicative of whether or not the motor is substantially at a target speed. A controller is communicatively coupled to the mirror assembly for controlling rotation of the rotating mirror, the controller generating a reference signal received by the motor assembly indicating the target speed for the rotating mirror. The reference signal is varied based at least in part upon an acceleration profile that accelerates the motor so that overshoot of the target speed is substantially reduced.

The minor assembly generates a lock signal indicative of whether or not the motor is substantially at a target speed.
