Abstract
An imaging system comprises a laser source for emitting a beam, a photoconductive surface, a scanning device and a controller. The controller designates at least a first part and a second part of each line of image data, corresponding to a first part and a second part of each associated sweep of the beam. The laser source is modulated based upon the first part of the line of image data during the first part of a first one of the associated sweeps of the beam. The laser source is not modulated according to image data for the second part of the first one of the sweeps. During the first part of a second one of the associated sweeps of the beam, the laser source is not modulated based upon image data. However, the laser source is modulated based upon the second part of the line of image data during the second part of the second one of the sweeps.
