The external heater assembly has a low mass, fast-acting heating element to transfer heat rapidly to and from the external surface of the elastomeric cover of the fuser roller. A pressure film belt assembly is also in operative association with the fuser roller, spaced from the external heater assembly. The pressure film belt assembly has a pressure applicator which maximizes thermal contact and mechanical energy to define an optimum nip pressure profile providing an extended fusing nip with the fuser roller, thereby yielding quick starting, with superior energy efficiency and exceptional temperature control for the fuser device that provides proper image quality for photos, text, and graphics for high quality reproductions with consistent gloss (luster). | 05-27-2010 |
20110236093 | SAFE RADIANT TONER HEATING APPARATUS WITH MEMBRANE - Apparatus for heating toner on a receiver having an ignition energy, having an energy source for providing input energy; and a membrane disposed adjacent to the receiver. The membrane receives the input energy from the energy source; stores a portion of the input energy; and radiates emitted energy that is absorbed by the toner, the receiver, or a combination thereof, wherein the absorption causes the temperature of the toner to rise above a desired temperature. The stored portion of the input energy is less than the ignition energy. | 09-29-2011 |
20130050348 | PRINTHEAD SUPPORT STRUCTURE INCLUDING THERMAL INSULATOR - A printing system includes a plurality of inkjet printheads for printing on a print media that is moved relative to the plurality of printheads and a support structure for locating the plurality of printheads relative to the print media.

20130083115 | INKJET PRINTING SYSTEM WITH CONDENSATION CONTROL SYSTEM - Methods for operating a printing system are provided. In one method, an inkjet printhead that is positioned by a support structure is caused to emit droplets of an ink including vaporizable carrier fluid toward a target area to emit droplets according to image data and a shield is used to separate the support structure from the target area to form a first region between the support structure and the shield and a second region between the shield and the target area with the shield providing an opening between the first region and the second region to allow the inkjet printhead to jet droplets to the target area. The shield is heated to a temperature that is at least equal to a condensation temperature of the vaporized carrier fluid in the second region. | 04-04-2013 |
20130083135 | CONDENSATION CONTROL IN AN INKJET PRINTING SYSTEM - Inkjet printing systems are provided. One inkjet printing system has a plurality of inkjet printheads, each having nozzles for jetting ink droplets having a vaporizable carrier fluid, a support structure to which the plurality of inkjet printheads are mounted, such that a face of each of the printheads of the plurality of printheads is positioned to jet the ink droplets toward a target area through which a receiver transport system moves a receiver during printing; and a shield between the support structure and the target area creating a first region between the shield and the target area with the shield having at least one opening through the shield through which the nozzles of the printhead can jet the ink droplets to the target area. An energy source supplies energy to cause the temperature of the shield to rise above a condensation temperature of vaporized carrier fluid in the second region. | 04-04-2013 |
20130120494 | REDUCING CONDENSATION ACCUMULATION IN PRINTING SYSTEMS - A printing system includes one or more printing system components positioned opposite a moving print media. A wick assembly can be attached to a printing system component to wick condensation away from a surface of the printing system component that is opposite the moving print media. A heating element can be in contact with one or both of the wick assembly and a printing system component. A protective layer can be attached to the surface of a printing system component that is opposite the moving print media to prevent condensation from forming on the component. A vacuum assembly can be positioned opposite the moving print media to produce suction over the print media that pushes humid air or some condensation into the vacuum assembly. | 05-16-2013 |
