Abstract
An imaging device has a photoconductive drum with a surface that is selectively discharged to create a latent electrostatic image for attracting toner for transfer to a media moving in a process direction. The image is divided into multiple segments along the process direction and discharged pixels per segment are counted. An accumulator keeps track of the numbers of pixels per revolutions of a roller that applies the toner to the drum. Upon meeting a predetermined deficiency in the counts of pixels in any given segment, an artificial image gets generated on the surface of the photoconductive drum that supplies the missing pixels, per segment. The image gets developed with toner, but does not transfer to the media. Lubrication occurs on the surface of the drum and each segment retains a relatively common number of imaging pixels that get developed over time.
