  • Apparatus and method for printing using a coating solid
    Patent number: 6935734
    Abstract: An apparatus for ink-jet printing including an ink-jet print head to jet ink, a coating solid, and a coating holder to support the coating solid, wherein the coating holder transfers a portion of the coating solid onto a medium to form a coating solid layer. The coating holder and coating solid may be combined in a removable cartridge. In addition, the medium may be an intermediate transfer medium, a media support medium, a transfer medium, or media, such as paper. A method for inkjet printing also includes applying a coating solid to a medium to form a layer of the coating solid, in a solid form, having predetermined thickness, and applying ink to the medium. The layer of coating solid may interact with the applied ink to destabilize colorant in the ink.
    Type: Grant

  • Ink jet semiconductor chip structure
    Patent number: 6502926
    Abstract: The invention provides a printhead for an ink jet printer and a method for making a printhead for an ink jet printer. The printhead includes a printhead body having a chip surface side, an ink surface side opposite the chip surface side and a first coefficient of thermal expansion (CTE). A semiconductor chip containing ink ejector devices is adhesively attached to the chip surface side of the printhead body. A stiffener is adhesively attached to the ink surface side to provide body stiffening during curing of the adhesive. The semiconductor chip has a second CTE and the stiffener has a third CTE wherein the second and third CTE's have a similar value. The invention provides an improved structure for printheads which resist warpage and/or breakage of the semiconductor chips during the manufacturing process used to make the printheads.
