  • Patent number: 7110127
    Abstract: Disclosed is a method of regionalizing a product for specific markets for the purposes of language localization, insuring compliance with local laws and standards, or theft prevention. The method is applicable to goods comprising an initially-sold machine or device and consumable items required by the machine or device. The method comprises regionalizing the consumable items; the first-installed consumable used in the machine or device then causes the machine or device to be regionalized, such that the machine or device subsequently only accepts consumables with the same regionalization. Also disclosed are apparatus to implement the method.

  • Patent number: 6648434
    Abstract: A printing system includes an inkjet printhead for selectively depositing ink drops on print media. An ink reservoir stores ink to be provided to the inkjet printhead. An ink level sensing circuit provides an ink level sense output that is indicative of a sensed volume of ink in the ink reservoir. A memory device stores sensor compensation information. A processor responsive to output of the memory device and the ink level sense output generates a compensated ink level sense output. The processor provides an estimate of available ink based on the compensated ink level sense output.

  • Publication number: 20020122082
    Abstract: A replaceable ink container for providing ink to a printhead of a printing system. The ink container has a fluid outlet configured for connection with the printhead. The ink container includes an ink reservoir having a first capillary member having a first capillary pressure, and a second capillary member having a second capillary pressure that is greater than the first capillary pressure such that the second capillary member has a higher resistance to ink flow than the first capillary member. An ink level sensor senses a low ink condition of the ink reservoir. The ink level sensor includes a C-shaped tube having first and second ports that fluidically communicate with only the second capillary member. The first and second capillary members abut one another at a capillary member interface, and the first port is positioned immediately adjacent to this capillary member interface.

    Abstract: The present disclosure relates to a replaceable printing component for use in a printing system. The replaceable printing component is configured for containing a supply of printing material for use by the printing system to form images on media. The replaceable printing component includes a sensor for sensing printing material in the replaceable printing component. The sensor provides a sensor output signal that is indicative of a printing material level in the replaceable printing component. Also included is a linking device that is electrically connected to the sensor. The linking device emits a broadcast signal that is indicative of the sensor output signal.
