ABSTRACT:
A method and apparatus adjusting the lateral position of an LED bar may minimize image banding in image-on-image systems having multiple LED bar imagers. A photoreceptor may be transported past a plurality of marking stations. At each marking station an LED bar imager extends in a direction perpendicular to the direction of transport of the medium. A mark may be sensed at each station and the lateral position of the LED bar, perpendicular to the direction of transport of the medium, may be adjusted according to the deviation of the position of the mark from a desired position.
