20090239016 | VARYING FLUOROELASTOMER CURE ACROSS THE ROLLER TO MAXIMIZE FUSER ROLLER LIFE - In accordance with the invention, there are image forming apparatus, fuser members, and methods of making fuser members. The method of making a fuser member can include providing a substrate having a longitudinal axis, providing a first flow coating solution including a fluoroelastomer polymer, and providing a second flow coating solution including a crosslinking agent. The method can also include mixing the first flow coating solution and the second flow coating solution to form a third flow coating solution and forming a continuous fluoroelastomer layer over a surface of the substrate by applying the third flow coating solution onto the substrate in a spiral pattern, wherein the crosslinking agent concentration can be varied along the longitudinal axis by changing the ratio of the first flow coating solution and the second flow coating solution in the third flow coating solution. | 09-24-2009 |
20100079560 | VARIABLE RATE FUSER RELEASE FLUID APPLICATION - According to various illustrative embodiments, an apparatus, method, and system for variable rate fuser release fluid application are described. In one aspect, the apparatus comprises a supply of release agent material. The apparatus also comprises a release agent metering roller supported for contact with the supply of the release agent material. The apparatus also comprises a variable speed drive arranged to effect movement of the release agent metering roller in an endless path at different surface velocities. The apparatus also comprises a donor roller supported in contact with the release agent metering roller and a fuser roller of a contact fuser, the donor roller arranged to convey release agent material from the release agent metering roller to the fuser roller at various rates depending on a surface velocity of the release agent metering roller, wherein the variable speed drive is operative independently of the fuser roller. | 04-01-2010 |
20100079561 | VARIABLE RATE FLUID FILM RELEASE IN AN INK JET PRINTER - An apparatus for ink jet printing, as well as corresponding method and system are described. The apparatus includes a source of fluid film, a fluid film metering roller supported for contact with the source of fluid film, a variable speed drive arranged to effect movement of the fluid film metering roller in an endless path at different surface velocities, a donor roller supported in contact with the fluid film metering roller, an ink jet printhead configured to emit ink, and a print assembly rotatably supported in the apparatus, the print assembly having a print assembly surface coupled to the donor roller, the print assembly configured to receive ink from the ink jet printhead and produce an image on media using the ink, wherein the donor roller is configured to convey the fluid film from the fluid film metering roller to the print assembly surface at various rates depending on a surface velocity of the fluid film metering roller, and at least one of the following: an amount of fluid film left on the donor roller, a film thickness of the fluid film on the fluid film metering roller, and a speed ratio between the fluid film metering roller and the donor roller, wherein the variable speed drive is operative independently of the print assembly. | 04-01-2010 |
20100098440 | Custom Application Fuser Roller System - A fuser roller system, utilized with electrographic or xerographic copying or printing devices, multiple fuser rollers, each of which includes a machine readable device (MRD) having identification data. The system also includes at least one MRD reader and at least one computer having a database of fuser rollers. The system facilitates use of custom fuser rollers by determining what type of fuser roller is appropriate to run a print job. Then it is determined whether an appropriate fuser roller is installed in the copying or printing device. If an appropriate fuser roller is installed in the copying or printing device, the print job is directed to the device. If an appropriate fuser roller is not installed in the copying or printing device, the appropriate fuser roller is identified using the identification data stored in the MRD and installed in the device. | 04-22-2010 |
20100111578 | APPARATUS FOR CLEANING FUSER ROLL - In a printer for forming toner images on a photoreceptor, the printer including a heated fuser roll with an elastomer-coated surface, an external heating roll, in contact with the heated fuser roll, the external heating roll includes a braking mechanism for generating frictional contact with the heated fuser roll thereby improving fuser cleaning | 05-06-2010 |
20100178087 | PASSIVE IR OIL RATE SENSOR - This is a system to coat oil on a fuser roller in a xerographic marking procedure. The system has an IR sensor which is located adjacent to the metering roller and which measures the emissivity of an oil film on the metering roller. Once the IR sensor determines the emissivity of this film, it conveys the emissivity reading to a controller. The controller then controls the metering roller speed to thereby control the oil film thickness. | 07-15-2010 |
