Publication number: 20100177151Abstract: An apparatus prints and/or fixes ink on a substrate, such as in ink-jet printing with UV-curable inks. A conformable member is positioned to contact an ink-bearing side of the substrate at a nip. The conformable member substantially comprises a silicone-based elastomer having a conformability from about 20 shore A to about 10 shore A. A radiation source directs radiation to the ink-bearing side of the substrate at the nip, the radiation suitable for curing the ink on the substrate. The apparatus is particularly useful for printing onto corrugated cardboard or otherwise non-planar surfaces, since the resulting ink image is impressed uniformly onto the substrate by the conformable member without voids in the ink layer in the recesses of the non-planar surface.Type: ApplicationFiled: January 13, 2009Publication date: July 15, 2010Applicants: XEROX CORPORATION, PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Michael D.

Publication number: 20100150598Abstract: This is an electrophotographic marking system that effectively cleans residual toner and toner additives from the surface of a photoreceptor of a marking system, by improved toner and toner agent removal expedients . This cleaning process reduces ghosting problems that had been encountered in final copies produced by electrophotographic systems such as in copier, printers and duplicators. This cleaning is accomplished by expedients such as increasing a cleaning brush bias, and by increasing the surface area of cleaning brushes used in the system. In addition, the development process is desensitized to the development of ghosting. This desensitizing is accomplished by expedients such as increasing the gap between the development roll and the photoreceptor and by reducing the AC development electrical bias.Type: ApplicationFiled: February 22, 2010Publication date: June 17, 2010Applicant: XEROX CORPORATIONInventors: BRUCE E.

Publication number: 20080279596Abstract: A specific magnet roll design for high speed semi-conductive magnetic brush (SCMB) development systems for magnetic image character recognition (MICR) printing is provided. The resulting magnetic field distributions include a more uniform radial field and enhance solid area development and halftone graininess without or substantially without bead carryout issues. In addition, this enhancement of solid area development enables magnetic toner in these hill speed SCMB systems that normally would not provide sufficient development latitude for MICR.Type: ApplicationFiled: May 9, 2007Publication date: November 13, 2008Applicant: XEROX CORPORATIONInventors: Michael D.

Publication number: 20080276334Abstract: Expressed Sequence Tags (ESTS) isolated from soybean are disclosed. The ESTs provide a unique molecular tool for the targeting and isolation of novel genes for plant protection and improvement. The disclosed ESTs have utility in the development of new strategies for understanding critical plant developmental and metabolic pathways. The disclosed ESTs have particular utility in isolating genes and promoters, identifying and mapping the genes involved in developmental and metabolic pathways, and determining gene function. Sequence homology analyses using the ESTs provided in the present invention, will result in more efficient gene screening for desirable agronomic traits. An expanding database of these select pieces of the plant genomics puzzle will quickly expand the knowledge necessary for subsequent functional validation, a key limitation in current plant biotechnology efforts.Type: ApplicationFiled: April 26, 2007Publication date: November 6, 2008Inventors: Mark S.

Patent number: 7177572Abstract: Electrodes are embedded in a biased charge roller of a xerographic device. The electrodes, which may run the length of the roller, are deposited on an insulating substrate. A semi-conductive conformable layer of a flexible elastomer covers the electrodes. The semi-conductive conformable layer limits current flow between electrodes and relaxes charge deposited on the roller surface. Stationary pre-nip and post-nip contacts apply the bias to the imbedded electrodes. The electrodes in the post nip region are biased to VPOST. The electrodes positioned in the pre-nip regions are either grounded or biased to VPRE<VPOST. The electroded biased charge roller may generate air breakdown in the post nip region, resulting in highly uniform charging.Type: GrantFiled: June 25, 2004Date of Patent: February 13, 2007Assignee: Xerox CorporationInventors: Christopher A. DiRubio, Michael D. Thompson, Gerald M. Fletcher, Charles A. Radulski
