20130222466 | Printer Having Drum Maintenance Unit Architecture For Controlled Application of a Release Agent - An inkjet offset printer includes at least one printhead to eject ink on a release agent applied to an image receiving member for subsequent transfer of the ink to the surface of a recording media. The release agent is applied to the image receiving member by at least two release agent applicators. The release agent can be selectively applied to process sheets of recording media of different sizes to improve print quality. Selective application of release agent to the image receiving member prevents release agent from migrating to a transfix roll, and subsequently to the back side of the media which affects the image quality. | 08-29-2013 |
20130335476 | SYSTEM AND METHOD FOR IMPROVING TEMPERATURE UNIFORMITY OF IMAGE DRUMS - A printer includes an image drum temperature regulation system that helps reduce thermal gradients on the image drum surface. The image drum temperature regulation system includes a feedback controller and a feed-forward controller. The image drum temperature regulation system operates the heaters and fan of the image drum with reference to a temperature difference between actual temperature of the image drum and a temperature setpoint and to the thermal effect of ejecting an ink image onto the image drum. | 12-19-2013 |

20140204150 | Release Agent Composition For Solid Inkjet Imaging Systems For Improved Coefficient Of Friction - A functional amine release agent displaying reduced coefficient of friction as compared to standard silicone oils, the release agent comprising a polydimethylsiloxane oil and a functional amine selected from the group consisting of pendant propylamines and pendant N-(2-aminoethyl)-3-aminopropyl; wherein the concentration of functional amine to polydimethylsiloxane oil is approximately less than 0.0006 meq/g. According to certain embodiments, the functional amine release agent is operable to impart a coefficient of friction of about 0.3 or more to the print media, resulting in improved finishing and converting equipment interaction. | 07-24-2014 |
