  • Patent number: 7822352
    Abstract: The present invention relates to an article, system and method for thermally conditioning an image forming apparatus. The image forming apparatus may incorporate a heating device and a component that includes a lubricant. The component including the lubricant may be preheated before movement and then rotated at reduced speeds prior to a printing operation. This may occur during an image forming apparatus cold start or power saver mode.
    Type: Grant

  • Patent number: 7698812
    Abstract: A method for forming a ceramic laminate ceramic laminate from first and second sheets of ceramic material, the sheets having a first and a second surface, wherein the first ceramic material has a different coefficient of thermal expansion than the second ceramic material and the outer layers comprises ceramic materials having substantially the same thermal properties, comprising (a) heating the first and the second sheets of ceramic material; (b) stacking the first and the second sheets of ceramic material wherein the second surfaces are opposed to one another to provide stacked sheets; and (c) pressing the stacked sheets and forming the ceramic laminate.

  • Patent number: 7403737
    Abstract: An apparatus and method are provided for the reduction of wrinkles formed in sheets of paper media which may contain various levels of absorbed moisture across the surface and which are processed through a fuser section of a printing or copying device. Protruding features may be provided laterally spaced apart by a desired paper width at the fuser nip to create a pressure contact area which constrains the outer longitudinal edges of the sheet of paper as it enters the nip.

  • Patent number: 7005611
    Abstract: A large area heater used, for example, in a laser printer belt fuser or as cooking surface, has an alumina substrate in which two bowed parts of alumina ceramic having opposed concave regions are formed together as a laminate. Electrical resistors are deposited on the laminate. The alumina laminate provides excellent resistance to uneven heating or other thermal stress. Alumina ceramic is readily shaped during manufacture and manufacturing costs and yield are good. A wide variety of large area heaters can usefully employ the laminate.
