  • Patent number: 6017158
    Abstract: An improved apparatus for reinking a ribbon of a printer ribbon cartridge provides a selected reinking pattern across the width of the ribbon. A porous member in contact with a source of ink has a height equal to a distance between a first edge of the ribbon and a distal edge of a double strike zone of the ribbon. The porous member is in contact with a transfer roller, which in turn is in contact with the ribbon. The ribbon moves through the printer cartridge along a path of a Mobius loop. As the ribbon passes the transfer roller for the first time, ink is provided to a single strike zone and to the double strike zone of the ribbon. As the ribbon passes the transfer roller for the second time, the ribbon is reversed given the pattern of the Mobius loop, and ink is provided again to the double strike zone, as well as to the other single strike zone. Twice as much ink is therefore applied to the double strike zone as to each of the single strike zones.

  • Patent number: 5758979
    Abstract: The inking mechanism of the present invention comprises one or more free-floating inking rollers which rotate within the housing of a printer cartridge between the inking brushes and the printer ribbon. While the rotation of the inking rollers is unlimited, the inking rollers are trapped between the inking brushes, the ribbon and the housing thereby limiting their freedom of movement. The free-floating aspect of the inking rollers provides a desirable pumping action against the inking brushes and the use of the inking brush, the ribbon, and the housing to trap the inking rollers eliminates the need for additional support structure.

  • Patent number: 5685653
    Abstract: A method and apparatus for extending the useful life of a printing ribbon by controlling the ratio of ink used to ink applied to the ribbon, while maintaining visual clarity of printed characters. A counter accumulates the number of characters printed, and the print density, over a preset period of time. The number of characters printed is compared with predetermined triggering numbers of characters, and the print density is likewise compared with a predetermined triggering print density. As a result of this comparison, the speed of the printer ribbon is increased to allow an increase in the ratio of ink applied to ink used, when the number of characters and print density are high. Conversely, ribbon speed is decreased when the number of characters printed during the preset time period, and the print density, are low, to prevent overinking and fouling of printer hammers. This condition applies when the ribbon is relatively new.

    Abstract: An ink reservoir (34) capable of maintaining an even distribution of a single color of ink on a printer ribbon is provided. The ink reservoir is used in ribbon cassettes (10) for typewriters and dot matrix printers. The ink reservoir (34) includes a series of cylindrical ink-carrying elements (50) separated by a series of separating sheets (52). The separating sheets (52) restrict or prevent the flow of ink from one ink-carrying element to another element. This maintains an even distribution of ink throughout the height of the reservoir which, in turn, results in an even transfer of ink from the ink reservoir onto a transfer roller and subsequently onto a ribbon. The even distribution of ink in the ribbon results in an even distribution of ink in the characters printed using the ribbon and, thus, improves print quality.

  • Patent number: 5198835
    Abstract: In a method of regenerating an ink image recording medium of a multilayered structure, after an ink image on the ink image recording medium is recorded, the surface of the heat-fusible ink layer of the ink image recording medium is uniformly charged. Then, a liquid ink for generating the ink layer, being placed under an electric field applied thereto, is supplied to the ink image recording medium. The liquid ink is prepared by dispersing heat-fusible ink powder into a liquid dispersion medium. As a result, the heat-fusible ink powder selectively sticks onto the portion on the ink release layer where the heat-fusible ink layer is absent because the ink was transferred. Finally, the ink image recording medium thus processsed is dried to remove the liquid dispersing medium.

  • Patent number: 5131768
    Abstract: A method and apparatus for replenishing depleted portions of an ink layer of an ink sheet formed with a conductive ink layer disposed on an insulating layer from which ink has been transferred, without unintentionally supplying ink to undepleted portions of the ink layer are provided. Electrically conductive replacement ink is charged and supplied onto an intermediate transfer roller having a dielectric layer disposed on an electrically conductive layer. Charge is supplied to the insulating layer side of the ink sheet and replacement ink on the intermediate roller contacting the ink sheet at depleted regions of the ink sheet is transferred from the intermediate roller to the depleted portions by electrostatic attraction and not to undepleted portions. The method and apparatus are adaptable for multi-color ink sheets and can be employed in connection with a printer or image forming device.

  • Patent number: 5059045
    Abstract: A cartridge ribbon (2) for impact printing containing an endless ribbon (4) initially carrying ink having dye as its only coloring matter. The initial dye is in heavy enough quantity to permit infrared readability of bar codes printed by the ribbon. Re-inking reservoir (16) transfers ink through drive gear (10) only to the track (28) which is impacted during printing. The ink in the reservoir is colored with carbon black. Bar code functioning is maintained by the carbon black added by re-inking. This limited presence of carbon black does not hamper ribbon feed unacceptably, while a ribbon with a full carbon-black ink would not feed well.

  • Patent number: 5015108
    Abstract: Apparatus for selectively reinking an endless ribbon in that portion of the ribbon known as the ribbon print track. The ribbon print track is created in an endless ribbon by the repeated striking of the ribbon by a print mechanism thereby deforming the ribbon and depleting it of ink. Reinking the entire ribbon uses more ink than is necessary. Reinking only the print track extends the life of the ribbon by selectively using the available supply of ink. The apparatus achieves this result by use of an ink reservoir which supplies ink to a drive roller, which through a rotating pinching movement in cooperation with another roller, advances a ribbon into a stuffing cavity of an ink cartridge. The ink reservoir is rotatably mounted and formed to apply ink only to that portion of the drive roller which corresponds to the print track of the ribbon.
