  • Patent number: 6963717
    Abstract: A fuser stripper baffle exit minimizes differential gloss marks due to paper contacting the fuser exit baffle. Portions of paper that touch the baffle cool differently than portions that don't, resulting in differential gloss in the paper path or spanwise direction. The exit baffle contains a series of axial-direction steps or plateaus in its upper surface, such that the highest step is nearest the fuser roll, while the lowest plateau is furthest from the roll. This reduces the surface area of the fuser stripper baffle exit that contacts the surface of the paper sheet as the paper sheet is stripped from the fuser roll. The paper thus touches the exit baffle for the minimum amount of time, thus minimizing the heat transfer to the baffle. This minimizes differential cooling effects which, in turn, minimizes differential gloss.

  • Patent number: 5803445
    Abstract: An arrangement has a rotor with rotor arms that are arranged in a drum-like manner around an axis of rotation and project on one side from a carrying element that is driven in rotation. The arrangement also has a sucker arrangement that includes a carrying arm which is driven by a drive. At a free end of the carrying arm there is arranged an extension arm with a suction head. The movement path of the suction head runs in the interior of the rotor, with the exception of an approximately V-shaped section of the movement path projecting in a radial direction outside the rotor. When the extension arm runs through this section, it passes through a cutout of the rotor in order to grip a corner region of a printed product and move the printed product into the interior of the rotor. A rotor arm then engages beneath the printed product and lifts it further in order to deliver it to a range of action of a removal conveyor.

  • Patent number: 5716046
    Abstract: In an apparatus for feeding an original document, the time which is needed until the first original document is transported onto a transportation path after storing original documents is shortened. The original documents stacked on an original document supporting plate are successively supplied one by one in order from an uppermost original document. A discharged original document is steadily and easily inserted between the original document supporting plate and the original documents stacked on the original document supporting plate. When a hopper sensor detects that the original documents are stacked on the original document supporting plate, the original document supporting plate is moved upward until the upper surface of the uppermost one of the original documents contact a level sensor. At this stage, the original documents are supplied successively one by one from the uppermost original document by a paper feeding mechanism.
