  • Patent number: 7973815
    Abstract: A method for maintaining a peel location and for peeling a layer of media from a surface in a thermal printer. An optical probe, that includes a light source and a photodetector, transmits light from the optical probe toward a first web. The web reflects a portion of the transmitted light onto the photodetector, which then outputs an electrical signal which is compared with a preselected signal level and the difference between them provides an indication as to how much adjustment the peel location requires. Adjusting the peel location may comprise changing environmental characteristics of the first web or the second web (surface) or adjusting a tension of the first or second web. The difference between the measured electrical signal levels is related to a physical distance of the first web from the desired peel location.

  • Patent number: 6744456
    Abstract: In a dye transfer printer, a donor web having successive dye transfer areas and opposite longitudinal edge areas alongside each one of the dye transfer areas is subjected to a longitudinal tension when the donor web is advanced in the printer. The longitudinal tension can stretch the dye transfer areas more than the edge areas because the dye transfer areas, but not the edge areas, are heated at a print head. According to the invention, the resistance of the edge areas relative to the dye transfer areas, to being stretched, is weakened so that the edge areas can be stretched substantially the same as the dye transfer areas. If the edge areas alongside a dye transfer area being used are stretched substantially the same as the dye transfer area, the likelihood of any creases being created in the next unused transfer area is substantially reduced. Thus, no line artifacts will be printed on a dye receiver during dye transfer in the printer.

  • Patent number: 6717603
    Abstract: A dye transfer printer uses a dye donor web that is capable of developing a crease-causing wave-like or ripple distortion across the donor web when the donor web is subjected to a longitudinal tension as it is advanced from a print head, over a web guide, and onto a web take-up spool in the printer. The web guide is positioned to extend across the donor web and is adapted to be bowed to effect a curvature across the donor web in proportion to the longitudinal web tension in order to urge the donor web to spread substantially widthwise to reduce the likelihood of the wave-like or ripple distortion developing across the donor web. If the wave-like or ripple distortion is prevented from developing in a dye transfer area being used, it is unlikely that any creases will be created in the next unused transfer area. Thus, no line artifacts will be printed on a dye receiver during dye transfer in the printer.

  • Patent number: 6109801
    Abstract: An ribbon spool and associated mounting spindle for a printer incorporates multiple longitudinal ribs on the spindle that fit into multiple longitudinal slots in the spool to acquire rotational lock between the spindle and spool. A latch at the end of selected ribs interacts with a lock ridge within the spool to acquire longitudinal lock between the spindle and spool. Placing the lock ridge near one end effectively prevents the spool from being inserted from the wrong end. The latch includes a spring-loaded detent action to hold the spool in place until an operator exerts sufficient force to overcome the latch for removal and replacement of the spool. The inner cylindrical surface of the spool is also designed to work properly with conventional spring-loaded frictional force spindles. However, the reverse is not true. Due to the sloping alignment edges on the ribs of the instant spindle, conventional spools may be blocked, thus preventing improper insertion of the old spools onto the new spindles.

  • Patent number: 5785438
    Abstract: A ribbon mask for use with a impact dot matrix printer is provided. The ribbon mask comprises a head confronting surface and a pair of opposed side plates each positioned on an opposite side of the head confronting surface. An obtuse angle is formed between said head confronting surface each of the opposed side plates. A pair of fitting tabs are also provided. Each fitting tab is positioned on one of the pair of opposed side plates. An acute angle is formed between each of the fitting tabs and a plane parallel to a plane in which the head confronting surface lies. As a result of this construction, when the ribbon mask comes in contact with a sheet of a recording medium, the ribbon mask is deformed so that a portion of the head confronting surface comes into contact with an end of a recording head, which in turn prevents the ribbon mask from interfering with the sheet of the recording medium.
