| 20080279582 | ELECTROPHOTOGRAPHIC APPARATUS - The present invention is an apparatus for refurbishing a fusing member. The apparatus includes a fusing member that contacts the toner image on a receiver medium and fuses the toner image to the receiver medium. The fusing member has an outer contact surface of a fluorothermoplastic resin The apparatus includes a tooling member positionable adjacent to the outer contact surface of the fusing member such that a pressure nip is formed between the outer contact surface of the fusing member and the tooling member. A heat source is provided for transferring heat to the fusing member and the tooling member, wherein the surface of the fuser member is engagable with the tooling member to rotate at a speed of at least 1 rpm at a pressure of at least 5 psi and at a temperature of at least 10° C. below the thermoplastic melting temperature of the outer contact surface for a time sufficient to resurface of the outer surface of the fuser member. | 11-13-2008 |
| 20080280035 | IN-LINE METHOD TO REFURBISH FUSER MEMBERS - The present invention provides a method of resurfacing a fuser member in-situ. The method includes providing a fuser member having an outer surface of a high temperature fluorothermoplastic. When it is determined that the outer surface is in need of resurfacing, the fuser member is rotated at a speed of at least 1 rpm while engaging the outer surface of the fuser member with at least one heating roller at a pressure of at least 5 psi at a temperature of at least 10° C. below the fluorothermoplastic melting temperature for a time sufficient to resurface of the outer surface of the fuser member. | 11-13-2008 |
| 20090087202 | ROLLER FUSER SYSTEM WITH FUSING MEMBER TEMPERATURE CONTROL FOR PRINTING - Internally-heated external rollers transfer heat rapidly to a fuser roller in an electrostatographic printer. Stored media process set points, input image content and input media type data are used to regulate the heat transfer rate by varying the nip width between the heated external rollers and the fuser roller. The rate of heat transfer and the rate of heat transfer adjustment are sufficiently rapid that many different media weights and types may be mixed in a print run without restrictions on media run lengths, without collation requirements per run, and without productivity losses due to slowing of feed rate for heavier receivers. | 04-02-2009 |
| 20090239172 | CHILLED FINISH ROLLER SYSTEM AND METHOD - An apparatus for fixing of toner onto a receiver, including: a non-contact fuser capable of fusing one or more layers of toner on a receiver such that one or more toner layers reach a fusing temperature above a glass transition temperature. The apparatus also includes one or more cooling finish rollers located downstream from the non-contact fuser to lower the toner temperature. | 09-24-2009 |
| 20090250830 | ELECTROPHOTOGRAPHIC APPARATUS - The present invention is an apparatus for refurbishing a fusing member. The apparatus includes a fusing member that contacts the toner image on a receiver medium and fuses the toner image to the receiver medium. The fusing member has an outer contact surface of a fluorothermoplastic resin The apparatus includes a tooling member positionable adjacent to the outer contact surface of the fusing member such that a pressure nip is formed between the outer contact surface of the fusing member and the tooling member. A heat source is provided for transferring heat to the fusing member and the tooling member, wherein the surface of the fuser member is engagable with the tooling member to rotate at a speed of at least 1 rpm at a pressure of at least 5 psi and at a temperature of at least 10° C. below the thermoplastic melting temperature of the outer contact surface for a time sufficient to resurface of the outer surface of the fuser member. | 10-08-2009 |
| 20100126021 | METHOD FOR REFURBISHING PRESSURE MEMBERS - The present invention provides a method of resurfacing a pressure member in a printer having a fuser member that is externally heated by a heater roller. The method includes providing a pressure member having an outer surface of a high temperature fluorothermoplastic. When it is determined that the outer surface is in need of resurfacing, the fuser member is removed from the printer, and the pressure member is mounted in the place of the fuser member. The pressure member is rotated at a speed of at least 1 rpm while engaging the outer surface of the fuser member with the heating roller normally used to heat the fuser member at a pressure of at least 5 psi at a temperature of at least 10° C. below the fluorothermoplastic melting temperature for a time sufficient to resurface of the outer surface of the pressure member. | 05-27-2010 |
| 20100329708 | FUSING APPARATUS FOR HIGH SPEED ELECTROPHOTOGRAPHY SYSTEM - A fuser and receiver release system and method are provided for improving the release of receivers in high speed of printing systems. This system controls the release of a receiver in conjunction with a fuser in a printing system, and specifically the efficiency and accuracy of the release system. One embodiment of this method includes a belt fuser that allows the separating of the heat transfer and release functions of the fuser such that fuser roller could be made of hard metal core that can be heated to high temperatures without the fear of delaminating elastomeric coatings which are common in roller fusing. | 12-30-2010 |
| 20110020024 | OPTIMIZED FUSING FOR HIGH SPEED ELECTROPHOTOGRAPHY SYSTEM - A fuser and receiver release system and method are provided for improving the release of receivers in high speed of printing systems. This system controls the release of a receiver in conjunction with a fuser in a printing system, and specifically the efficiency and accuracy of the release system. One embodiment of this method includes a belt fuser that allows the separating of the heat transfer and release functions of the fuser such that fuser roller could be made of hard metal core that can be heated to high temperatures without the fear of delaminating elastomeric coatings which are common in roller fusing. | 01-27-2011 |
| 20110052234 | ENHANCED FUSING OF RAISED TONER USING ELECTROGRAPHY - Printing of information with a distinct tactile feel can be accomplished by electrographic techniques. Such electrographic printing includes electrographic printing of raised images to selected areas of a receiver member using electrographic techniques so that they are fixed according to the properties of the raised print such as according to the mass per unit area or toner height. In one embodiment, by slowing down the process speed of the fuser to allow for a longer dwell so that the large toner particles and/or toner mass needed to make raised image will properly adhere to the print media without artifacts. To keep the energy requirements and the cost of the equipment down a speed switching technique is used that slows the process speed of the fuser so that the raised image is properly fused on a wide range of paper types. | 03-03-2011 |
