| 摘要 |
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.
