Abstract: A discharge device usable in an electrostatographic printing machine uses a plurality of emissions to discharge an image receiver, such as a photoreceptor, of the printing machine. The discharge device can be used as a charge erase device, a reconditioning device, an imaging device, or a combination of these. In embodiments, the different emissions come from different groups of emitters within the device, such as from rows of emitters or from groups interspersed within a single row. In other embodiments, at least some of the emitters are tunable and can emit more than one type of emissions. For example, tunable LEDs could be employed in the device.

Abstract: Xerographic printers may be provided with a photoreceptor belt manufactured so that transparent permanent optical registration marks are formed in defined selected minor areas of the belt without physically weakening the belt, as is the case with belt holes. These permanent registration marks are sufficiently transparent for a conventional belt holes sensor to optically detect them by illumination through those transparent areas of the photoreceptor. The photoreceptor is preferably a plural layer organic photoreceptor with an internal optically opaque metallic ground plane layer, and the optical registration marks are formed by oxidizing defined areas thereof. This may be accomplished by the simultaneous selective application of illumination to these selected minor areas of the photoreceptor, while adjacent areas of the photoreceptor are not illuminated, plus the application of electrical current from a voltage source applied through the belt in those areas.
