Abstract: The electrographic printing of one or more multi-channeled layers having a particular pattern by electrographic techniques that produces a three-dimensional optical waveguide electrographically. Such electrographic printing comprises the steps of forming a desired print image, electrographically, on a receiver member utilizing predetermined sized marking particles; and, where desired, forming one or more final multi-channeled layers utilizing marking particles of a predetermined size or size distribution.

Abstract: Electrographic printing of one or more multi-channeled layers produces a specialty item. Such electrographic printing includes forming a desired print image, electrographically, on a receiver member utilizing predetermined sized marking particles; and, where desired, forming one or more final multi-channeled layers utilizing marking particles of a predetermined size or size distribution.

Abstract: Printing one or more layers using toner and/or laminates to form one or more multi-channeled layers, with a particular pattern, including forming a desired image, for example, electrographically, on a receiver member. The multi layered channel printing apparatus and related method and print incorporates one or more static layers, and one or more moveable layers that allow a fluid to move through the micro channels via an opening or through a direct fill. It also incorporates particles in the channels to act as a packing material for separation of components of samples. The packing material can either be applied directly or using the electrographic printing process. An optional capping layer or substrate may then be applied.

Abstract: The present invention provides an apparatus for allowing the resurfacing of a cylindrical member in a printer having a fuser member that is externally heated by a heater roller. The apparatus 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 heater 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 the outer surface of the cylindrical member.

Abstract: In view of the above, this invention is directed to printing methods including electrographic printing wherein toner and/or laminates form one or more multi-channeled layers, with a particular pattern. The multi-channeled layers are printed, such as by electrographic techniques, using the steps of forming a desired image on a receiver member and incorporating channels of toner that form a microfluidic item. In the microfluidic items the channels act as interconnects to transfer fluids between incorporated micro-devices such as pumps, devices, and sensors. The channels can also be designed to act as splitters ports, reservoirs, filters, and separators to allow a variety of specialty micro-devices to be developed with the printer.

Abstract: A system and method using an electrographic printer for printing of a print including an image and a particular pattern using techniques that also allows the selective application of non-conventional toners to an image formed on a printed media using registration marks to locate the original image on the printed media in order to provide proper alignment of the non-conventional toner image to the original printed image. The system employs two printers, the first is a conventional EP printer with the capability (internal or via driver software) to place registration marks on the print media along with the printed image, and a second printer adapted to read the registration marks on the printed media. Once the registration marks are read the non-conventional toner image is applied by the second printer in relative relation the positions of the read registration marks.

Abstract: Often times the glossing process results in an image artifact consisting of locally lighter image a fixed distance from the lead edge as a print is glossed. This artifact is most visible in areas of medium but consistent image. The present invention provides methods for reducing this artifact.
