  • Patent number: 7177046
    Abstract: A method for producing and outputting at least one printed page is provided in which at least one printed page containing several blocks is produce using a first program module. Each block contains first image data of image elements. A representation parameter characterizing image characteristics of a particular block is assigned to each block. An outputting unit outputs image elements on the basis of second image data. The image characteristics of these image elements are determined by outputting parameters. Second image data are produced block by block from first image data using several image processing procedures according to the outputting parameter of the outputting unit. The outputting unit outputs the printed page together with the second image data.

  • Patent number: 7130547
    Abstract: In a system and method for remote maintenance, remote configuration and/or remote operation of an electrophotographic printing or copying system, a data processing system is connected with a communication unit of the printing or copying system via a network. Given a deactivated printing or copying system, the communication unit receives first data transmitted by the data processing system via the network and processes the transmitted first data. After receiving the first data, the communication unit activates a data processing unit of the printing or copying system. After the activation of the data processing unit, second data can be transmitted between the data processing system and the data processing unit.

  • Patent number: 7100503
    Abstract: In a method and system to generate a print image on a carrier material, the surface of a print substrate is covered with at least one of an ink-repelling and an ink-attracting layer. In a structuring process, ink-attracting regions and ink-repelling regions are generated corresponding to a structure of the print image to be printed. An ink-attracting carrier substance is applied which can be an ink or other carrier substance on the print substrate surface that adheres to the ink-attracting regions and is not accepted by the ink-repelling regions. The carrier substance is fixed and subsequently the fixed carrier substance is inked with ink at least once. The applied ink is transferred to the carrier material. Before a new structuring process, the print substrate surface is cleaned and newly covered.

  • 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: 7047340
    Abstract: A parallel databus assembly and method includes modules connected to parallel signal lines, each of the modules having a databus driver being in immediate connection with the signal lines and a controller connected to the databus driver. At least some of the parallel signal lines are data lines for transmitting data or control lines for controlling the data transmission of the data via the data lines. A clock generator for generating a bus frequency with which the signals transmitted in the signal lines are clocked is connected to the databus drivers. The databus drivers are fashioned such that the signals to be transmitted from and to the data lines and the control lines are accepted during a clock pulse prescribed by the clock generator and are emitted during a following clock pulse.

  • Patent number: 7043186
    Abstract: A fixing station and a method for fixing toner images on a carrier material. The fixing station has an arrangement for moving a carrier material in a first direction and in a second direction opposite the first direction, a heat radiation source, which heats the carrier material to fix a toner thereon, and a covering device which is arranged between the carrier material and the heat radiation source and is movable parallel to the direction of the carrier material between an opened and closed position, so that while in the closed position, it blocks radiation from reaching the carrier device and in an opened position allows the radiation to heat the carrier material. The method includes delaying the opening and closing of the covering device so that a previously fixed area of the carrier material is not subjected to additional radiation from the heat radiation source.

  • Patent number: 7039350
    Abstract: The invention relates to a transfer printing station for an electrographic printer or copier wherein the transfer is carried out by means of a transfer roller (5) that simultaneously forces a web of paper (8) against a photoconductor drum (1) in such a manner that no defective spots (data loss) or bright spots in scanning patterns, indefinite scanning patterns and horizontal stripes in scanning patterns occur on the paper web (8). This is especially important for the subsequent printers of a system of printers that have to print onto a paper that is stressed by the fixing station of the preceding printer. The transfer roller (5) is disposed in a swiveled support unit (4) that comprises, in addition to the guide of the paper web (8), transfer jaws (11) along the photoconductor drum (1). The inventive transfer printing station is especially suitable for use in printing systems with a plurality of printers or copiers.

  • Patent number: 7038805
    Abstract: A method and apparatus for electronic archiving of a data stream that has both text and graphics includes separating form data that stays the same from document to document from variable data that varies from document to document. The form data is treated differently in the archiving process from the variable data. For example, only one copy of the form data need be stored, while the smaller data files of the variable data occupy less storage space. Index data is generated to facilitate overlay of the form data and variable data to permit recreation of the original documents. The data is converted into a printer-specific data format to facilitate separation into the different data types.

  • Patent number: 7027078
    Abstract: With a control device to optimize charge image generation in an electrophotographic process, a light-sensitive and temperature-sensitive photoconductor layer is exposed pixel-by-pixel with a temperature-sensitive light source. The photoconductor layer becomes more sensitive with rising temperature, such that given a predetermined light quantity it discharges deeper. With rising temperature, given the same actuating power, the light source emits a lesser luminous power. The luminous power of the light source and the discharge depth of the photoconductor layer are temperature-dependent via adjustment of the current and/or the luminous duration that flows through the light source and/or the luminous duration. During the measurement of the discharge depth, a temperature measured in the course of the measurement event is used as a reference value for the temperature compensation of the light source.
