Abstract

A device for separating a transfer material or media, such as paper, from a photoreceptor in a xerographic printing machine is disclosed. The device, positioned underneath the photoreceptor, forms a small diameter roll or bump that causes the transfer material to separate from the photoreceptor. Currently, separation of paper from a photoreceptor or a transfer belt is accomplished using, for example, stripper fingers which can be damaging to the photoreceptor since the fingers are in constant contact with the photoreceptor. Also when stripper fingers are incapable of removing the transfer media from the photoreceptor belt, the media has a tendency to jam under the stripper fingers, which may result in blemished copies as well as bent stripper fingers.

BUMP INDUCED SELF STRIPPING PHOTORECEPTOR BELT

(Cont'd)

A device for separating a transfer material or media, such as paper, from a photoreceptor in a xerographic printing machine is disclosed. The device, positioned underneath the photoreceptor, forms a small diameter roll or bump that causes the transfer material to separate from the photoreceptor. Currently, separation of paper from a photoreceptor or a transfer belt is accomplished using, for example, stripper fingers which can be damaging to the photoreceptor since the fingers are in constant contact with the photoreceptor. Also when stripper fingers are incapable of removing the transfer media from the photoreceptor belt, the media has a tendency to jam
under the stripper fingers, which may result in blemished copies as well as bent stripper fingers.

The disclosed device separates a transfer material or media such as paper from the photoreceptor or transfer belt of a printing machine by causing the transfer media to pass over a small bump. The bump separates the media, such as paper, used during transfer from the photoreceptor belt. The small radius of the bump, which is on the order of 15 to 19 mm, is located at a point where separation of the two is most effectively achieved for a given printing system.
