20110182633 | APPARATUSES USEFUL IN PRINTING AND METHODS OF FIXING MARKING MATERIALS ONTO MEDIA - Apparatuses useful in printing and methods of fixing marking materials onto media are disclosed. An exemplary apparatus useful in printing includes a first roll including a first shaft and a first surface; a second roll including an axially-extending inner portion including a second shaft; an axially-extending outer portion over the inner portion; at least a first annular gap and a second annular gap extending axially between the inner portion and the outer portion, the first annular gap being axially spaced from the second annular gap; and a second surface forming a nip with the first surface. The inner portion and the outer portion of the second roll bend in opposite directions when the first roll and the second roll are loaded by applying a first force to the first shaft in a first direction and applying a second force to the second shaft in a second direction opposite to the first direction. | 07-28-2011 |
20120039647 | FIXING DEVICES INCLUDING EXTENDED-LIFE COMPONENTS AND METHODS OF FIXING MARKING MATERIAL TO SUBSTRATES - Fixing devices including extended-life components and methods of fixing marking material to a substrate are provided. An exemplary embodiment of the fixing devices for fixing toner to a substrate in printing includes a first fixing member including a first surface; a thermal energy source for heating the first surface of the first fixing member to a fixing temperature; and a second fixing member including a second surface. The first surface and the second surface form a fixing nip configured to receive a substrate including a surface and marking material comprising toner disposed on the surface. The first fixing member and the second fixing member are operable to apply a pressure of at least about 300 psi to the substrate and toner and to heat the toner to a sufficiently-high temperature, at the fixing nip, to fix the toner to the substrate. | 02-16-2012 |
20120255489 | QUARTZ TUBE LEVELING APPARATUS AND SYSTEMS FOR SIMULTANEOUS LEVELING AND PINNING OF RADIATION CURABLE INKS - Systems for leveling UV-curable gel ink include a leveling member having a conformable surface. The leveling member is a quartz tube rotatable about a longitudinal axis, and connected to a mandrel, with conformable VITON O-rings interposing the mandrel and the quartz tube. A UV source is disposed within the quartz tube, and configured to emit light through the quartz tube and the conformable surface onto a surface of a substrate passing through a leveling or pressure nip defined by the quartz tube and a backing member or pressure belt. | 10-11-2012 |
20130070037 | TRANSFIX ROLLER FOR USE IN AN INDIRECT PRINTER WITH AN IMAGE RECEIVING MEMBER HAVING A THIN WALL - A transfix roller is adapted for use with a thin walled image receiving member in an indirect printer. The transfix roller is centrally supported to present a more uniform pressure profile in the nip formed with the image receiving member. An interference fit between the central shaft and the roller sleeve enables the transfix roller to be made without an additional process to secure the shaft to the sleeve. | 03-21-2013 |
20130120513 | IMAGE RECEIVING MEMBER WITH INTERNAL SUPPORT FOR INKJET PRINTER - A thin wall ink image receiving member enables the ink image receiving member to reach operational temperatures from a cold state more quickly than image receiving members used in previously known printers. The thin wall image receiving member includes at least one annular support member fixedly mounted against the inner surface of the cylindrical wall to enable the image receiving member to provide adequate pressure in a nip formed with a transfix roller to transfer an ink image from the image receiving member to media in the nip. | 05-16-2013 |
20130293616 | Transfix Roller with Adaptive Center Loading for Use in an Indirect Printer - An image transfer system for use in an indirect printer includes a support roller for a transfix roller. The support roller is configured to apply pressure to a center portion of a nip formed between a transfix roller and an imaging drum while the transfix roller applies pressure to the ends of the nip. This configuration is particularly advantageous for use with imaging drums and transfix rollers having thin walls. | 11-07-2013 |
20130335496 | Printer having Skewed Transfix Roller to Reduce Torque Disturbances - An inkjet offset printer includes an imaging drum and a transfix roller skewed with respect to and defining a continuously applied or an uninterrupted nip with the imaging drum to reduce torque disturbances and media wrinkling issues.
