US Patent:

6667752, Dec 23, 2003

Filed:

Dec 28, 2001

Appl. No.:

10/029268

Inventors:

Moritz P. Wagner - Walworth NY
Neville R. Phillips - Rochester NY
Dennis A. Abramsohn - Pittsford NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 1504

US Classification:

347130, 399128

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.

US Classification:

399/128000

Abstract:

A discharge arrangement 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 arrangement can be used as a charge erase arrangement, a reconditioning device, an imaging device, or a combination of these. In embodiments, the different emissions come from different groups of emitters within the arrangement, such as from different stations including rows of emitters or 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 arrangement.

Filed:

Dec 7, 1999

Appl. No.:

9/457094

Inventors:

Dennis A. Abramsohn - Pittsford NY
Neville R. Phillips - Rochester NY
Jimmy E. Kelly - Rochester NY
Damodar M. Pai - Fairport NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 2100
G03G 2106

US Classification:

399128

Abstract:

An electrostatographic printing machine that includes an erase light source that reduces the quantity of charges on the photoreceptor surface and a reconditioning light source that reduces both the quantity of the trapped charges and the variation in the quantity of the trapped charges among the different portions of the image area.

Appl. No.:

9/457598

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G21/00

US Classification:

399128

Abstract:

A method involving a photoreceptor having a front surface and a rear surface, including: (a) creating an electrostatic latent image on an image area of the photoreceptor front surface; (b) developing the latent image with developer particles to form a developed image; (c) transferring the developed image off the photoreceptor wherein the photoreceptor retains residual charges in the image area after the transferring of the developed image off the photoreceptor; and (d) discharging at least a portion of the residual charges in the image area, after transferring the developed image off the photoreceptor, by directing charge dissipation emissions at a portion of the image area and at a corresponding region on the photoreceptor rear surface directly opposite the image area portion.
