| 20080279596 | LOW GRAININESS PRINTING AND MICR PRINTING WITH SCMB AND EA-SCMB SYSTEMS - 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. | 11-13-2008 |

| 20100111575 | TRIMMING SYSTEM FOR STABILIZING IMAGE QUALITY FOR HIGH PERFORMANCE MAGNETIC BRUSH DEVELOPMENT - A device for metering developer material to a predefined developer material bed height on a donor member, including a trim bar being mounted a predefined spacing from the donor member; and a magnetic member positioned adjacent and along the length of the trim bar, the magnetic member coacting with the trim bar to obtain the predefined developer material bed height on the donor member. | 05-06-2010 |
| 20100150598 | TONER AND ADDITIVE REMOVAL SYSTEM FOR COPIER OR PRINTER - 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. | 06-17-2010 |
| 20100177151 | METHOD AND APPARATUS FOR FIXING A RADIATION-CURABLE GEL-INK IMAGE ONTO A SUBSTRATE - 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. | 07-15-2010 |
| 20110102491 | Cooler For A Printer - An inkjet printer has been developed that reduces the effects of show-through by depositing ink onto a cooled print medium. The inkjet printer includes a printhead and a cooler. The printhead is configured to eject ink onto an ink receiving member as the ink receiving member is transported along a portion of a media path through the inkjet printer. The cooler is positioned proximate the media path to cool the ink receiving member prior to the printhead ejecting ink onto the ink receiving member. | 05-05-2011 |
