  • Patent number: 10570288
    Abstract: The current technology is directed to red and red-shade violet pigments with an hexagonal ABO3 structure of the form Y(In, M)O3 in which M is substituted for In in the trigonal bipyramidal B site of the ABO3 structure, and where M is a mixture containing Co2+ and charge compensating ions, or M is a mixture containing Co2+ and charge compensating ions, as well as other aliovalent and isovalent ions.
    Type: Grant

  • Publication number: 20160319097
    Abstract: The current technology is directed to an iron-substituted copper aluminum delafossite pigment, as well as a gallate version of the same. In particular, the materials may be defined as iron-substituted copper aluminum delafossite, CuFexAl1-xO2 and the gallate, CuFexGa1-xO2 where X=0.01 to 1.00, for example, CuFe0.15Al0.85O2, and CuFe0.15Ga0.85O2. The pigments are dark-brown to black, absorb most light in the visible spectrum, but have low absorbance and high reflectance in the near-infrared regions, specifically light from about 700 nm-2500 nm.

  • Patent number: 7319829
    Abstract: An electrophotographic image forming device may use a feedback loop to determine environmental conditions and accordingly set one or more operating parameters. The device may detect a resistance/capacitance characteristic of a feedback loop comprising an interface between a first component and a second component of an image forming unit. The interface may be one in which a toner image is transferred during image forming device operation. A controller may adjust the detected resistance/capacitance characteristic in response to an age of one of the first component or the second component, thereby accounting for the age or wear of the components.

  • Patent number: 6970663
    Abstract: An image forming device prints on specialty media comprising a first and second area having different media properties. The device prints on the first area at a first transfer voltage level selected in response to a media property of the first area. The device prints on the second area at a second transfer voltage level selected in response to a media property of the second area. The device changes from the first transfer voltage level to the second transfer voltage level when a predetermined location on the specialty media, on which no image is formed, is within the transfer nip.
