  • Patent number: 6176575
    Abstract: A scheme for extending the life of a drum maintenance unit that applies a release agent to the surface of a transfer drum in a phase change ink inkjet printer determines a release agent usage ratio based on an ink coverage percentage for each print. The release agent usage ratios for each print are accumulated, and each time the release agent ratio accumulation value has an integer change a maintenance counter in the drum maintenance unit is decremented by one from an initial nominal number of prints to produce a number of prints remaining. Once the number of prints remaining reaches a specified low value, the maintenance counter may be decremented by one for each additional print to allow for variability in the amount of release agent consumed per print from projected values. As a result depending upon a particular customer usage profile a drum maintenance unit having a nominal life of 30,000 prints, for example, may be extended by over 40%.

  • Patent number: 6158909
    Abstract: A Z-fold print media handling system for printing banners and the like uses an inkjet printing mechanism without a tractor-feed. A series of stuttering stopping and starting steps generates varying static and dynamic frictional forces to separate the first sheet of a Z-fold stack from the remainder of the stack. Both conventional cut-sheet media and Z-fold media are fed using the same printing mechanism, which pulls the media toward a printzone through frictional engagement with a first surface of the media. To prevent printhead crashes and smearing the image near the perforations joining the Z-fold sheets, the printhead to media spacing is increased for Z-fold media over the standard spacing used for cut-sheet media. A cam feature is incorporated into the media drive clutch disk to determine whether an operator has set a selector lever for cut-sheet or Z-fold printhead to media spacing.

  • Patent number: 6158346
    Abstract: A prototyping method and apparatus incorporating the invention enables rapid fabrication of heterogeneous parts with non-planar and/or layer-by-layer printing. An electronically addressable array of micro-electrodes is employed as a "printing" panel, A processor controls the printing panel through use of two dimensional planar slice data. Such slice data is used to address electrodes that correspond to points in the slice image. When the printing panel is brought close to a flat powder bed, a static electrical field at each addressed electrode attracts particles to the electrode's surface. The powder image on the printing panel electrodes is then placed over a substrate and the powder image is released to the substrate by applying a reverse polarity voltage to the electrodes. Multiple applications of powder image layers, with intervening fixing of each image layer, enables a three dimensional object to be rapidly constructed.

  • Patent number: 6126344
    Abstract: The present invention provides a novel structure of a tape cartridge accommodating a printing tape and an ink ribbon used for printing, which prevents the printing tape from being stuck in a cartridge case or the ink ribbon from being slackened. The tape cartridge of the invention has a mechanism for preventing an end of the tape from being reversely moved back into the cartridge case. A typical structure of the mechanism includes an anti-inversion system which prevents a tape core having a tape wound thereon from rotating in a reverse direction, that is, a direction opposite to a normal rotating direction for printing. The anti-inversion effects are removed when the tape cartridge is set in a printing device such as a tape writer to ensure smooth feeding of the tape for printing. When the tape is forcibly pressed back into the cartridge case, a movable platen clamps the tape between the platen and a fixed wall to prevent reverse movement of the tape.
