| 20090116882 | ELECTROSTATOGRAPHIC METHOD - The present invention is a method of forming a toner image on a receiving sheet. The method includes forming an electrostatic image on a primary image member and toning the image with a dry toner to form a toner image. The toner includes toner particles having a diameter of between 4 and 10 microns and transfer assisting particles appended to the toner particles surface. The transfer assisting particles have a diameter of between 20 and 100 nm. The toner image is transferred from the primary image member to an intermediate image member having an overcoat layer, the overcoat layer having a Young's modulus of from 250 to 500 MPa. The toner image is transferred from the intermediate image member to a receiving sheet wherein the intermediate image member drives the primary image member or the receiving sheet. | 05-07-2009 |
| 20100148386 | METHOD FOR REFURBISHING CYLINDRICAL MEMBERS - The present invention provides a method of resurfacing a cylindrical member in a printer having a fuser member that is externally heated by a heater roller. The method includes providing a cylindrical 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 cylindrical member is mounted in the place of the fuser member. The cylindrical 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 cylindrical member. | 06-17-2010 |

| 20100271417 | IMAGE QUALITY MATCHING IN A MIXED PRINT ENGINE ASSEMBLY SYSTEM - A method and system for improved image quality using an image quality matching method is used to match the optical density of single prints produced on multiple print engines by first sensing the optical density of a first image produced on a first print engine and then sensing the optical density of a second image produced on a second print engine before comparing the optical densities and determining if they are substantially equal. If they are not equal set points and exposures are adjusted on one or both print engines until the differences between the optical densities is less than 0.05, preferably 0.03. The density is changed by adjusting the initial voltage on the primary imaging member of at least one print engine and/or by adjusting the exposure of the primary imaging member of at least one print engine. | 10-28-2010 |
| 20100296823 | DUAL ENGINE SYNCHRONIZATION - A method of synchronizing the timing of a plurality of physically coupled print engines wherein the receiving sheet is inverted between a first and a second print engine including determining a position of one or more timing marks on a first primary imaging member in a first print engine having a first timing, directing a receiving sheet from the first print engine to a second primary imaging member in a second print engine having a second timing, determining an actual arrival time of the receiving sheet relative to a fixed position in the second print engine, and calculating an optimum timing offset using the one or more timing marks on the first primary imaging member, the actual arrival time of the receiving sheet and the distance of the non-printable area to the fixed position in the second engine. | 11-25-2010 |
| 20110103860 | ELECTROSTATOGRAPHIC APPARATUS HAVING IMPROVED TRANSPORT MEMBER - The present invention is an electrostatographic reproduction apparatus which includes a primary imaging member for producing an electrostatic latent image, a development station for applying toner particles to said latent image which forms a developed toner image, and a transfer station for transferring said developed toner image from the primary imaging member to a receiver. A fuser assembly is included for fixing the developed toner image to the receiver, to form a fused toner image on the receiver. An endless transport member is provided for transporting the receiver to or from the fuser assembly, the transport member having a substrate bearing an oil-absorbing porous layer that would tribocharge positively upon contact with negatively charged toner particles, and a porous overcoat outermost layer that does not tribocharge positively upon contact with negatively charged toner particles. | 05-05-2011 |
| 20110116840 | Multicolor electrophotographic print engine - A method and system for printing image documents using a variety of toners where some toners using a multi-development station having two or more development stations. These toners are co-printed prior to fixing, on the receiver by the multi-development station. | 05-19-2011 |
| 20110157615 | SYSTEM FOR GENERATING PERSONALIZED DOCUMENTS - A system with for capturing and storing an image of a user's handwritten alphanumeric characters. The characters are stored in memory in association with a standard alphanumeric character set such as an ASCII character set. A text document can then be transcribed into the stored handwritten alphanumeric characters for resembling a handwriting of the user. The characters can be represented by mathematical functions such as Taylor Series or McLauren Series and can be digitally reproduced based on the stored functions. | 06-30-2011 |
