  • Patent number: 7085510
    Abstract: To suppress spread of fire from a fixing chamber of a fixing station in an electrophotographic print or copy device, in the event of a fire, in order to partition a fixing chamber for a recording medium in a fireproof manner, arranged at the openings of the fixing chamber is a safety apparatus made of an elastic sealing element and a counter-element, between which the recording medium is guided through. The sealing element is comprised of a fiberglass tube, inside which an elastic filling material or an elastic spreading element is situated. When the sealing element is pressed on the counter-element, a clamp region for the recording medium is formed, via which the opening of the fixing chamber can be sealed and a burning segment of the recording medium can be extinguished. Additionally, ashes present on the recording medium can be removed.

  • Patent number: 6449458
    Abstract: A fixing station for a printer or copier includes a heating device for fusing toner to the carrier material and a cover that is selectively insertable between the heating element and the carrier material. The cover may be a window blind type cover. Where two sided fixing is provided, both heating devices have a cover. The cover may have an energy storage spring to cause the heating device to be covered in the event of an emergency. An electro-magnetic locking device may be provided to retain the cover in an open position.

  • Patent number: 4716418
    Abstract: Apparatus for the ejection of ink droplets having a fluid filled channel having a discharge opening at one end, and a cross-sectional expansion at the other, so that pressure waves within the channel produce by a tubular transducer are reflected from the cross-sectional expansion with reversal of operational sign or polarity. Unipolar pulses having symmetrically and trailing edges excite the transducer, and the droplet is ejected from the discharge opening as a result of the superimposed directed and reflected pressure waves produced by the transducer.

  • Patent number: 4368477
    Abstract: A printing head for an ink mosaic printing device is provided with a plurality of diagonally extending ink ducts having downstream ends converging at a printing location on the printing head to form a printing grid pattern. The downstream leading ends of the ducts are formed with wedge-shaped tapered portions, each having a leading edge wall carrying a discharge orifice for ink droplets. By virtue of this construction of the ink ducts, more ink ducts may be used to form the grid pattern and the various discharge orifices may be placed closer to one another to provide higher printing resolution.
