  • Patent number: 7139094
    Abstract: A scanner is connected to a host computer. A scanner control routine is installed onto the host computer and used to generate and forward control signals to the scanner or multi-function device. Using the scanner control system, manager or routine, one or more scanned image destinations are defined and one or more scanning parameters are defined that are particularly appropriate for each such scanned image destination. Each scanned image destination is associated with one of a number of pre-named scanner destinations that can be selected using the scanner. These pre-named destinations usually have generic or otherwise meaningless names that are not associated with any particular destination or location. The user uses the control panel of the scanner or multi-function device to select one of the pre-named destinations. The scanner or multi-function device forwards this selected destination to the host computer.

  • Patent number: 6665505
    Abstract: This invention relates to the packaging and subsequent removal of dry marking materials that tend to clump or bridge when shipped or stored in containers. Human operators are presently instructed to agitate such containers before installation into a marking engine but such agitation is unreliable. The present invention involves placement of agitation vanes on a displaceable inner seal within the cartridge such that such vanes will break apart clumps and bridges of the marking material during installation of the container upon the marking engine.

  • Patent number: 6633738
    Abstract: This invention relates to the packaging and subsequent removal of particulate matter that tends to stick in its storage container. Particular application of the present invention is to cartridges for storing marking materials such as electrophotographic toners and solid ink jet inks. A mechanism and process for increasing visibility into a container holding particulate matter is disclosed. The cleaning mechanism includes a drive mechanism capable of moving a cleaning member proximate to the inside surface of the container.

  • Patent number: 6609820
    Abstract: This invention relates to the packaging and subsequent removal of material that tends to clump or congeal when shipped or stored in containers. A mechanism and process for agitating material held in a container is disclosed. The agitating mechanism includes a device such as a spring for storing potential energy in a locked down position. When desired, the potential energy is released, and an agitating member moves through the materials to break apart clumps or congealed materials in order to aid flow rates and uniformity. One embodiment of the present invention relates to cartridges for storing marking materials for reprographic systems.

  • Patent number: 4956666
    Abstract: A highly productive copier for use in a secure area or building is described. The copier includes a transparent electrical coil mounted either upon or within the copier's exposure platen and accompanying circuitry coupled thereto for detecting the proximity of metal such as those having magnetic or ferromagnetic properties. A document sheet fed to the platen for copying is sensed for the presence of the metal. Metal is present in confidential documents that have been made with metal containing toners and which are to be copied only by those authorized for copying same. A user identification system is provided for allowing users to identify themselves to the machine for allowing copying of confidential documents. Nonconfidential documents may be copied without requirement of identification. The copier is highly productive because it may be used with known high speed document feeders such as recirculating feeders without requiring a waiting period for the coil to be moved relative to the document.
