  • Patent number: 7798627
    Abstract: An ink stick comprises an ink stick body having first and second opposed ends. A first interlocking face on the first end and a first interlocking face on the second end have complementary nesting shapes and are oriented to allow the first interlocking face of an end of the ink stick body to nest with a first interlocking face of an end of an adjacent ink stick when in a linear section of a feed path of an ink delivery system. A second interlocking face on the first end and a second interlocking face on the second end have complementary nesting shapes and are oriented to allow the second interlocking face of the ink stick body to nest with a second interlocking face of an end of an adjacent ink stick when in a non-linear section of the feed path.

  • Patent number: 7801453
    Abstract: In accordance with certain aspects, an adaptive system and method are implemented to estimate the level of a consumable such as toner on a gauge that accommodates machine-to-machine variances, individual machine degradation over time, and otherwise correct over time for various inaccuracies by applying an error compensation that can be used in subsequent replenisher computations. Over the lifetime of an imaging machine, such as a copier or printer device, these error compensations can increase the accuracy of the particular machine, to accommodate various deviations from nominal constraint assumptions as a result of differences in one or more operating constraints.

  • Patent number: 7798464
    Abstract: This is a mounting support that secures an electrostatic marking machine to the deck of a ship or other structure. This support provides vibration-isolating systems for shipboard mounting of these marking machines. The US Navy has imposed strict one-man, short-time requirements to mount and unmount electrostatic marking machines on a ship's deck. A key feature of the present embodiments is a double-threaded stud that lifts the machine off the floor onto the isolation mounts while securing it to the mount which is bolted to the ship's deck. The present configuration satisfies the new Navy mandate.

  • Patent number: 7800785
    Abstract: The teachings as provided herein relate to a watermark embedded in an image, and methodology for same, that has the property of being relatively indecipherable under normal light, and yet decipherable under UV light. This fluorescent mark comprises a substrate containing optical brightening agents, and a first dot design printed as an image upon the substrate. The first dot design has as a characteristic, the property of strongly suppressing substrate fluorescence. A second dot design having a property of providing a differing level of substrate fluorescence suppression from that of the first dot design such that when rendered in close spatial proximity with the first dot design image print, the resultant image rendered substrate suitably exposed to an ultra-violet light source, will yield a discernable image evident as a fluorescent mark.

  • Patent number: 7800777
    Abstract: A first series of control patches is printed with a first marking engine. A second series of control patches is printed with a second marking engine. Relative reflectance values of the patches printed with the first and second marking engines are measured with respective first and second engine response sensors. Based at least on a difference in the measured relative reflectance values of the control patches printed with the first and second marking engines, a relative engine to engine error is determined. The engine to engine error is decomposed into components. Based on the decomposition, adjustment of at least binary values of a digital image is determined so that print density of a first marking engine output substantially matches print density of a second marking engine output.
