Patent ID: 7907161

Claim:
An image forming device that includes an adaptive correction system, comprising: a light beam driver; a detector that detects one or more characteristics of a light beam during available periods while the device is performing an operational process; a controller that determines that an aberration exists based on data obtained by the detector and controls the light beam driver to compensate for the aberration while the device is performing the operational process; a light emitting device that emits the light beam; and a beam splitter that splits the light beam into a first beam and a second beam, the first beam scanning across a photoreceptor of the device and the second beam scanning across the detector in a manner that corresponds to the first beam scanning across the photoreceptor, wherein the detector detects the second beam to produce the data and the controller controls the light beam driver based on the data, and the controller compensates for an aberration in a slow scan direction based on the characteristics detected by the detector by reordering operational data from a received order to a compensating order.
