摘要： A printing machine for transferring a phase change ink onto a print medium includes a component for applying a phase change ink in an image, an imaging member for accepting the image and transferring the image from the imaging member to the print medium and a pressure member positioned in association with the imaging member to form a nip through which the print medium passes. The pressure member includes an outer layer with a tailored electrical conductivity to eliminate ghosting in duplex printing modes. The outer layer comprises a composite of a polymer and carbon nanotubes and/or graphenes. A similar outer layer may be implemented on a pressure roller in a direct-to-paper printing machine.

摘要： A printer for transferring a phase-change ink onto a substrate comprises components for conveying the substrate along a path through the printing machine, a printing station including a plurality of printheads disposed along the path and configured to transfer the phase-change solid ink onto the substrate as it is conveyed along the path, a plurality of metal backing rollers facing the plurality of printheads and arranged to support to the substrate passing between the backing rollers and the printheads, and a spreader station receiving the substrate from the printing station and configured to spread the phase-change solid ink on the substrate, the spreader station including a spreader roller and a metal pressure roller opposing the spreader roller. Each of the non-oiled metal rollers includes a coating that is an oleophobic that has low adhesion toward the solid ink image but sufficient lateral friction as to not slide against the ink or paper web.

摘要： An imaging device includes a substantially continuous web of media, and a web transport system configured to transport the continuous web along a web path. A print station is positioned along the web path and is configured to apply ink to the continuous web. A temperature leveling ink spreader is disposed along the web path downstream from the print station. The temperature leveling ink spreader includes a leveler roller including a heater configured to generate thermal energy to heat the leveler roller to a spreading temperature. The leveler roller is positioned to be partially wrapped by the continuous web to generate a predetermined dwell time between the continuous web and the leveler roller as the continuous web is being transported to equalize the temperatures of the web and ink on the web to within a predetermined range about the spreading temperature. The temperature leveling ink spreader includes a pressure roller positioned adjacent the leveler roller to form a spreading nip therebetween through which the continuous web is fed after the predetermined dwell time. The spreading nip is configured to apply a predetermined pressure to the continuous web and the ink thereon.

摘要： A system for use with a phase change ink imaging device comprises a leveler roller disposed along a web path downstream from a printing station. The leveler roller is formed of a thermally conductive material and includes a heater configured to generate thermal energy to heat the leveler roller to a leveling temperature. The leveler roller is positioned to be partially wrapped by the continuous web in order to generate a predetermined dwell time between the continuous web and the leveler roller as the continuous web is being moved. The predetermined dwell time is configured to allow conductive heat transfer to occur between the continuous web and the leveler roller to equalize the continuous web and the melted phase change ink temperatures on the web to within a predetermined range about the leveling temperature. A midheater is disposed along the web path downstream from the leveler roller. The midheater is configured to heat the continuous web and the melted phase change to a midheating temperature that is greater than the leveling temperature.
