| 20080279582 | ELECTROPHOTOGRAPHIC APPARATUS - The present invention is an apparatus for refurbishing a fusing member. The apparatus includes a fusing member that contacts the toner image on a receiver medium and fuses the toner image to the receiver medium. The fusing member has an outer contact surface of a fluorothermoplastic resin The apparatus includes a tooling member positionable adjacent to the outer contact surface of the fusing member such that a pressure nip is formed between the outer contact surface of the fusing member and the tooling member. A heat source is provided for transferring heat to the fusing member and the tooling member, wherein the surface of the fuser member is engagable with the tooling member to rotate at a speed of at least 1 rpm at a pressure of at least 5 psi and at a temperature of at least 10° C. below the thermoplastic melting temperature of the outer contact surface for a time sufficient to resurface of the outer surface of the fuser member. | 11-13-2008 |
| 20080279587 | DIGITAL MULTI-COLOR PRINTING MACHINE - A printing unit for a digital multi-color printing machine, in particular for an electrophotographically operating, preferably sheet-printing printing machine, said printing unit comprising at least one transfer element ( | 11-13-2008 |

| 20100247162 | DEVELOPER STATION FOR AN ELECTROGRAPHIC PRINTER HAVING REDUCED DEVELOPER AGITATION - A developer station and method for an eletrographic printer is provided that reduces developer agitation. The developer station includes a sump of magnetic developer, and a magnetic brush roller mounted above said sump and having a rotatable magnetic core surrounded by a substantially cylindrical toning shell rotatably mounted with respect to the core. The toning shell defines a nip at its closest point to the photoconductor element. A tangent line tangent to the cylindrical toning shell at the nip is oriented substantially vertically, and the magnetic developer is applied to the toning shell at an angular distance of no more than about 120° from said nip. The toning shell may be eccentrically mounted with respect to the magnetic core and is substantially closest to the rotatable magnetic core within about +30° and −30° from said nip. Such a configuration advantageously reduces the residence time of the developer on the toning shell. | 09-30-2010 |
| 20100329708 | FUSING APPARATUS FOR HIGH SPEED ELECTROPHOTOGRAPHY SYSTEM - A fuser and receiver release system and method are provided for improving the release of receivers in high speed of printing systems. This system controls the release of a receiver in conjunction with a fuser in a printing system, and specifically the efficiency and accuracy of the release system. One embodiment of this method includes a belt fuser that allows the separating of the heat transfer and release functions of the fuser such that fuser roller could be made of hard metal core that can be heated to high temperatures without the fear of delaminating elastomeric coatings which are common in roller fusing. | 12-30-2010 |
