ABSTRACT:
Control circuitry associated with an electrophotographic imaging device is adapted to operate in conjunction with a sensor to adjust operating parameters, including an imaging power. The sensor detects a reflectivity of a developed image and the control circuitry uses this detected information and information related to reflectivity of the underlying surface and the developing toner to determine whether the developed image is produced as desired. The control circuitry adjusts imaging power in response to a comparison between the detected reflectivity and a target reflectivity. In one embodiment, a predetermined halftone pattern is developed over a range of imaging powers and an optimum operating point is determined from the iterations. A predictive model may be generated based on many data points to select imaging power based on optimized surface potentials.
