Abstract:
Many devices, such as printers, work with one or more removable unit. Often, the removable units have an electronic circuit that used to communicate with the device. It may be desirable to provide a replacement unit in these devices. The replacement unit must include an electronic circuit that is able to communicate with the original device. Disclosed is a method and apparatus where a replacement unit is provided with a new electronic circuit and a used electronic circuit. The new electronic circuit is electrically connected to the used electronic circuit and uses the used electronic circuit to facilitate communication with the host device.
Abstract:
Image recording devices, such as electrophotographic devices, laser printers, copiers, and fax machines, often have a cartridge that utilizes a drive gear to transmit rotational force from the printer to the print cartridge. Also, it is desirable to remanufacture print cartridge both to reduce waste and to save resources. Therefore, it may be desirable to provide a drive gear mechanism that is easily replaced or reused when a print cartridge is remanufactured.
Abstract:
A drive gear for a generally cylindrical imaging component. The drive gear includes a body for engaging the generally cylindrical imaging component; a cylindrical shaft attached to the body, the cylindrical shaft having an end surface; and three prongs extending longitudinally outward from the end surface. Each prong may include an extension member extending perpendicular to the prongs and the cross-sectional area of the extension members may be less than the cross-sectional area of the prongs.

Abstract:
A method of remanufacturing a replaceable consumable unit includes providing the replaceable consumable unit including a first electronic circuit, with the first electronic circuit being at least partially inoperable; providing a second electronic circuit; communicatively connecting the second electronic circuit to the first electronic circuit; and intercepting, by the second electronic circuit, signals sent by an imaging system to the first electronic circuit.
Abstract:
The present application is directed to methods and devices for remanufacturing imaging cartridges. An installation handle for positioning an electronic circuit on the imaging cartridge includes a first end, and an adhesive is releasably attached to the first end. The installation handle is adapted for positioning an electronic circuit on a surface of the imaging cartridge while the electronic circuit is releasably secured to the installation handle by the adhesive.
Abstract:
A method of cleaning and coating a used organic photoconductive drum is disclosed. Using this method remanufacturers can reliably reuse certain used organic photoconductive drums which could not be reused without this method. The method comprises providing a used organic photoconductive drum, cleaning the surface of the used organic photoconductive drum, applying a new surface layer comprising a non-volatile non-polar dielectric fluid such as a silicone oil with a viscosity of less than 200 cSt at 40 degrees Celsius. The resulting liquid surface on the used organic photoconductive drum provides wear resistance, and improved electrical characteristics allowing the used organic photoconductive drum to be used at least a second time.
Abstract:
A universal inkjet cartridge usable in an inkjet printer the inkjet cartridge having an inkjet tank, the inkjet tank storing ink and having an upper surface and a lower surface is disclosed. Mounted on the lower surface are configurable color identification tabs and mounted on the upper surface are printer identification fins, the configurable color identification tabs are configured to allow the universal inkjet cartridge to be used in multiple inkjet cartridge locations within the inkjet printer identified by the printer identification fins.
Abstract:
Systems and methods of remanufacturing an imaging cartridge include providing the imaging cartridge comprising a developer material supplying roller, a developer roller, a developer blade which regulates a layer of thickness of the developer material on the outer surface of the developer roller, the developer blade held in a first position to exert a first pressure on the outer surface of the developer roller, providing a replacement developer material having a set of characteristics, and adjusting the position of the developer blade to a second position to exert a second pressure on the outer surface of the developer roller, the second position of the developer blade selected to function with the replacement developer material having the set of characteristics.
Abstract:
Techniques for spoofing an imaging device adapted for reading data from an electrical storage device to determine a volume of ink in an ink container include providing a replacement electrical storage device for use with the ink container, the replacement electrical storage device comprising memory locations; and responding, by the replacement electrical storage device, to reads of memory locations of the replacement electrical storage device by returning data to the imaging device which causes the imaging device to calculate an inaccurate initial volume of ink stored in the ink container.
