  • Capacitive toner level sensor
    Patent number: 10466617
    Abstract: A toner container according to one example embodiment includes a housing having a reservoir for holding toner. A first electrode and a second electrode are positioned on the housing. The first electrode and the second electrode form a capacitor having a capacitance that changes in response to a change in an amount of toner in the reservoir between the first electrode and the second electrode. The first electrode includes a first rod and the second electrode includes a second rod spaced from the first rod.
    Type: Grant
    Filed: December 19, 2017

  • Air funneling inkjet printhead
    Patent number: 7273275
    Abstract: Some embodiments of the present invention provide a inkjet printhead having an internal ink reservoir, an ink via in fluid communication with the ink reservoir, a filter tower extending into the ink reservoir, and one or more walls at the base of the filter tower. In order to promote the movement of bubbles toward and into the ink via, the wall(s) at the base of the filter tower can converge and be inclined toward the ink via, and can have one or more protrusions thereon and/or recesses therein.

  • Single piece filtration for an ink jet print head
    Patent number: 7147314
    Abstract: A multi-chamber inkjet print head includes a plurality of individual print head ink chambers that share a common ink filter and are in fluid communication with an ink flow regulator. An associated method of assembling a print head base having at least two separate fluid conduit paths filtered by a single piece of filter includes the steps of: (a) positioning a single piece filter between at least two separate ink receptacles associated with a print head and at least two respective ink conduits; and (b) sealing at least two separate ink paths between the at least two separate ink receptacles associated with the print head and the at least two ink conduits, such that the single piece of filter is in concurrent fluid communication with the at least two separate ink paths.
