  • Patent number: 6687468
    Abstract: A roll fusing apparatus for effectively heating and fusing quality toner images on various different thicknesses of substrates is described. The apparatus includes a frame, a heated fuser roller having a first end and a second end respectively mounted to the frame; a pressure device mounted to the frame and forming a fusing nip with the heated fuser roller, the heated fuser roller and the pressure device being movable for receiving, heating and applying a nip force to toner images being moved through the fusing nip on various different thicknesses of substrates; a rotatable cam providing a varying amount of pressure to the pressure device in response to the thickness of the substrate being fed into the nip of the fusing apparatus; a drive shaft for rotating the cam; and a controller for selectively moving the cam in response to the thickness of the substrate.

  • Patent number: 5528808
    Abstract: An installation tool for stringing a tensioned wire between an anchor point and a retaining point, including a sleeve having a slidably mounted pin inside. A tip of the pin holds a loop end of the tensioned wire (such as a coronode in a corotron wire assembly), and protrudes from an end of the sleeve. When the tip holding the loop end of the tensioned wire is placed adjacent to a retaining pin, and the tip is retracted into the sleeve, the loop end of the wire slides onto the retaining pin, where it may rest in a securing notch. A spring may be used to bias the tip of the pin to retract or protrude from the end of the sleeve positioned adjacent to the retaining point. An end of the pin protruding from the sleeve end opposite the retaining point may be used independently or in cooperation with a biasing spring to move the tip of the pin into and out of the sleeve. The sleeve may include gripping areas and or finger loops to permit the user to accurately manipulate the tool.
