20120223118 | WEB MEDIA MOVING APPARATUS - An apparatus for moving a continuous web of print media includes a roller having an axis of rotation. The roller includes a pattern of recesses and ridges positioned along the axis of rotation of the roller. A second section of the roller is located between a first section of the roller and a third section of the roller as viewed along the axis of rotation. The roller includes a profile as viewed along the axis of rotation in which the diameter of the ridges located in the first section of the roller and the diameter of ridges located in the third section of the roller are greater than the diameter of the ridges located in the second section of the roller. | 09-06-2012 |
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 |
20140035984 | WRINKLE ELIMINATION FOR SOLID INKJET WEB PRINTER - A solid inkjet web printer for reducing wrinkles on a web including a solid ink jet engine for jetting a patterned layer of solid jettable ink and a system having a processor, and a spreader, the spreader having a pressure roller and a spreader roller forming a nip and means for adjusting the force applied at the nip. The processor controls the adjustment of the force applied by the pressure and spreader rollers to the printed portion on the web causing the spreader to reduce the force when the non-image portion is in the nip. A sensor for providing a signal to the processor indicates the location of the image and non-image portions of the web. | 02-06-2014 |
20140375723 | STAGGERED PRINTHEAD PRINTER WITH CONTOURED MEDIA GUIDE - A printing system including a staggered inkjet printhead including at least two inkjet nozzle arrays arranged along first and second print lines in an alternating pattern, wherein the inkjet nozzle arrays along a particular print line alternate with non-printing regions. A media guide including first and second media guide surfaces is used for guiding receiver media along a media path past the first and second print lines of the inkjet printhead. At least one of the media guide surfaces is contoured such that it is closer to the staggered inkjet printhead along portions of the associated print line that correspond to the associated inkjet nozzle arrays than it is for at least some portion of the associated print line that corresponds to the non-printing regions. | 12-25-2014 |
20140375724 | INKJET PRINTER WITH CONTOURED MEDIA GUIDE ROLLER - A printing system including a staggered inkjet printhead including at least two inkjet nozzle arrays arranged along first and second print lines in an alternating pattern, wherein the inkjet nozzle arrays along a particular print line alternate with non-printing regions. A media guide including first and second rollers is used for guiding receiver media along a media path past the first and second print lines of the inkjet printhead. A center roller having a contoured media guide surface is positioned between the first and second rollers for guiding the recording media along the media path between the first and second print lines, wherein the diameter of the center roller is smaller for portions of its length corresponding to the inkjet nozzle arrays of the first print line than it is for at least some portion of its length corresponding to the non-printing regions of the first print line. | 12-25-2014 |
