Abstract:
1. A method of operating a xerographic printing apparatus, the xerographic printing apparatus including a rotatable photoreceptor having a photoreceptor surface, a cleaning device for removing marking material from the photoreceptor, and a printing apparatus controller that controls operations of the xerographic printing apparatus, the method comprising: charging the photoreceptor surface to a fixed voltage, discharging at least a portion of the charged photoreceptor surface to an exposed voltage; developing the discharged portion of the photoreceptor surface by providing a cleaning field between the charged photoreceptor surface fixed voltage and a developing bias voltage; reducing the cleaning field; generating a developed image on the photoreceptor using the reduced cleaning field; and scanning the developed image after reducing the cleaning field, where the developed image is scanned using a sensor to generate a scanned image.
