20090154948 | ENHANCED FUSER OFFSET LATITUDE METHOD - Electrophotographic printing of one or more layers of toner using a method of enhancing fuser offset latitude to enable the printing of a wide range of toner mass laydown using electrophotography. This method encompasses the steps of forming multicolor toner images, determining the amount of clear overcoat mass laydown as a function of the color mass laydown or non-raised mass laydown and fusing the clear toner overcoat and the multicolor toner image at a fusing temperature determined by the maximum total mass laydown and the nip width to provide good adhesion to the receiver member while optimizing fuser offset latitude. | 06-18-2009 |
20090286177 | Adjustable gloss document printing - A method and system for printing adjustable gloss image documents using a variety of toners where some toners have a relatively low melt viscosity and others have a relatively high melt viscosity. These toners are co-printed prior to fixing, on the receiver proximate to and overlying at least a portion of each other. | 11-19-2009 |
20090291274 | DEVELOPER FOR SELECTIVE PRINTING OF RAISED INFORMATION BY ELECTROGRAPHY - The use of electrographic printing to prepare prints which have a desired tactile feel or raised information in a controlled manner by utilizing a developer having toner particle size larger than 50 microns volume average diameter and carrier particles larger than the toner particle size such that the volume average distribution overlap between the toner distribution curve and carrier particle distribution curve is less than 35% and the carrier and toner particles have a volume average diameter size differential equal to or greater than 5 microns or the ratio of carrier-to-toner volume average diameter exceeds 1.25. | 11-26-2009 |
20100232821 | SELECTIVE PRINTING OF RAISED INFORMATION USING ELECTROGRAPHY - Printing of information with a distinct tactile feel can be accomplished by electrographic techniques. Such electrographic printing includes the steps of forming a desired print image, electrographically, on a receiver member utilizing standard size marking particles; and in areas of the formed print image, forming raised information by printing at least a first raised image and a second raised image. The print and raised images are fixing on the receiver member. The raised images are applied using toner particles having diameters substantially larger than the diameters standard size toner particles used for applying the print image. | 09-16-2010 |
20110103860 | ELECTROSTATOGRAPHIC APPARATUS HAVING IMPROVED TRANSPORT MEMBER - The present invention is an electrostatographic reproduction apparatus which includes a primary imaging member for producing an electrostatic latent image, a development station for applying toner particles to said latent image which forms a developed toner image, and a transfer station for transferring said developed toner image from the primary imaging member to a receiver. A fuser assembly is included for fixing the developed toner image to the receiver, to form a fused toner image on the receiver. An endless transport member is provided for transporting the receiver to or from the fuser assembly, the transport member having a substrate bearing an oil-absorbing porous layer that would tribocharge positively upon contact with negatively charged toner particles, and a porous overcoat outermost layer that does not tribocharge positively upon contact with negatively charged toner particles. | 05-05-2011 |
20120045265 | CHARGE REMOVAL FROM A SHEET - A method of removing charge from a charged sheet prior to stacking the charged sheet is disclosed. The method includes moving the charged sheet through a set of nipped rollers while a first roller has an AC voltage applied thereto so that a first side of the charged sheet is in contact with the first roller and has its charge substantially dissipated, whereby charge substantially remains on a second side of the charged sheet in contact with a second roller. The method further includes using at least one non-contact charge removal device to remove charge from the second side of the charged sheet, and stacking the discharged sheet. | 02-23-2012 |
20120107559 | INTERMEDIATE TRANSFER MEMBER AND IMAGING APPARATUS AND METHOD - An intermediate transfer member for electrophotography includes a substrate and a non-ceramer polyurethane compliant layer. Disposed directly on the compliant layer is an outermost surface layer consisting essentially of a non-particulate, non-elastomeric ceramer or fluoroceramer and nanosized inorganic particles that are distributed within the non-particulate ceramer or fluoroceramer in an amount of at least 5 and up to and including 50 weight % of the outermost surface layer. This intermediate transfer member can be incorporated into a suitable imaging apparatus for forming a toned image on a receiver element. | 05-03-2012 |
