Abstract
A method and apparatus for correcting banding defects in a photoreceptor image forming apparatus. The method or apparatus may form one or more images using one or more laser beams to alter an electrostatic charge on a photoreceptor, check the one or more images for one or more sets of image perfections arising from electric field attenuation in the photoreceptor, and compensate for the electric field attenuation. The method or apparatus may further form a compensated image.
