Abstract: A handheld device for testing printer cartridges interfaces with a computer for processing of test results. Multiple testing devices may be coupled to the computer. In one embodiment, each testing device includes a base board and an adaptor board. The base board includes a host processor and a computer interface. The adaptor board comprises a cartridge-specific socket for retaining a printer cartridge to be tested and test circuitry. The adaptor boards may be interchanged. The device may obtain power from the computer interface. A computer program communicates with the test device and displays the results of the tests through execution of a suitable application or program. The application may present a pass/fail indication to a user and tally the number of passed/failed cartridges. The device for testing printer cartridges may include a sensor for detecting cartridge information and a computer program for altering the cartridge identification.

Abstract: An apparatus such as a wireless temperature control system or a method for controlling an HVAC unit from a central location may include a control transmitter for sending programming data. One or more thermostats, each wired to an associated HVAC unit or units, have a wireless component for receiving the programming data from the control transmitter via a localized wireless network. The one or more thermostats of the system are not dependent upon the control transmitter or the localized wireless network for continued operation. Using this apparatus or method, a user may, among other things, transmit programming data to one or more HVAC units from one central location.

Abstract: An integrated inkjet-cartridge refilling system that is comprised of an arrangement of mechanical, electrical, electronic, pneumatic, and software elements, which is used by an operator in a retail environment to automatically connect one of many types of inkjet cartridges that are used in printing devices and refill the cartridge.

Abstract: A method for operating an ink jet cartridge refurbishment facility includes an utilizing an apparatus to refurbish ink jet cartridges. The apparatus includes a number of stations and accessories that perform the recovery and filling aspects of the ink jet cartridge refurbishment process. The method for operating the ink jet cartridge refurbishment facility may include receiving one or more used ink jet cartridges directly from each of a number of ink jet device users, refurbishing at least a portion of the used ink jet cartridges at the ink jet cartridge refurbishment facility, and distributing one or more replacement ink jet cartridges to each respective ink jet device user.

Abstract: An apparatus for refurbishing used ink jet cartridges and a method for operating an ink jet cartridge refurbishment facility. The apparatus includes a number of stations and accessories that perform the recovery and filling aspects of the ink jet cartridge refurbishment process. This apparatus may be one of a number of machines used in an ink jet cartridge refurbishment facility where ink jet device users may drop-off their used ink jet cartridges and pick-up replacement ink jet cartridges at the same location that refurbished the ink jet cartridges.

Abstract: A method and apparatus for refurbishing used ink jet cartridges. The apparatus utilizes an interchangeable cradle attachment arrangement that can hold virtually any type of ink jet cartridge. After the ink jet cartridge is placed in an ink jet cartridge cradle, a vacuum is applied to the print head of the cartridge to drain any excess ink. After draining excess ink, the ink jet cartridge can be replenished using the fill gun that is included in the ink jet cartridge refurbishing system.

Abstract: An apparatus for delivering one or more messages to a computer printer sufficiently self-contained so as to require neither support or nor interface with additional equipment in order to deliver the one or more messages.

Abstract: A drum cover or protector includes features that allow it to be used with substantially any xerographic device cartridge designed to be used in a xerographic device adapted to handle standard paper sizes. The drum protector may be secured to the cartridge in a protecting position. In this position, the protector covers the drum and blocks objects from coming into contact with the drum surface. The drum protector also includes an arrangement that prevents any critical part of the drum surface from coming into contact with the cover itself.
