Abstract
A printing apparatus includes a charging device and a photoreceptor adjacent the charging device. The charging device transfers a charge to the photoreceptor. Also, a charge patterning device is adjacent the photoreceptor. The patterning device patterns the charge on the photoreceptor to form a latent image charge. Additionally, an automated cleaning device is adjacent the charging device. The charge patterning device periodically moves by the charging device and the charge patterning device to simultaneously clean the charging device and the charge patterning device.
