DISCHARGE DEVICE FOR PRINTING MACHINE

PROBLEM TO BE SOLVED: To provide a discharge device used in an electrostatographic printing machine which uses a plurality of emissions in order to discharge an image receiver such as a photoreceptor of the printing machine. SOLUTION: This discharge device can be used as a charge erase device, a reconditioning device, an image forming device or a combination of the same. In embodiments, the different emissions come from different groups of emitters within the device, such as from a plurality of rows of emitters or from a plurality of 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 can be used in the device. COPYRIGHT: (C)2003,JPO
