  • Paper skew detection system
    Patent number: 8075086
    Abstract: A system and method that enables web paper skew detection by monitoring print head motor position. An inline full width array sensor actively tracks the alignment of the print heads across the print zone and actively moves the heads to maintain alignment. If the paper starts to skew across the print zone, a color misregistration error will be detected and the print units will be moves with respect to each other to maintain alignment. The absolute position of the print heads can be monitored by tracking the steps sent to each motor to maintain alignment.

  • Toner yield analysis for monitor and replacement of consumables within a print system
    Patent number: 8078068
    Abstract: Systems and methods are described hereinto to provide a notification when a predetermined event occurs that is related to a consumable. A print engine outputs hard copies based on electronically received data. One or more toner cartridges that are utilized by the print engine to place toner onto a hard copy substrate. A meter monitors and provides a level of remaining toner for each of the one or more cartridges. A yield component receives level data from each meter to compare to an expected yield and an expected grams per impression, wherein if the expected yield and/or the expected grams per impression are outside of a predetermined threshold, a signal is output.

  • Segmented ink stick
    Patent number: 8075118
    Abstract: A method facilitates insertion of a segmented ink stick into an ink feed system of a phase change ink jet printer. The method includes bending of a flexible strand between ink stick segments during insertion of the ink stick segments and then straightening the flexible strand to orient the ink stick segments in the ink feed system.

  • Adjustable idler rollers for lateral registration
    Patent number: 8074982
    Abstract: An assembly including nip assemblies spaced apart from one another along a first axis extending in the lateral direction. Each nip assembly including a driven wheel and an idler roller. The driven wheel rotatably supported about the first axis and the idler roller cooperating with the driven wheel to engage the sheet there between. The idler roller rotatably supported about a second axis. The first or second axis being selectively moveable relative to the other of the first or second axis between a first and second orientation. In the first orientation, the second axis extending parallel to the first axis, and in the second orientation the second axis extending at an oblique angle to the first axis. The selective movement of the second axis pivoting about a third axis substantially extending through a centerline common to both the driven wheel and the idler roller of each nip assembly.

  • Recording material processing apparatus having image forming apparatus and post processing device
    Patent number: 8078093
    Abstract: A recording material processing apparatus includes an image forming apparatus, a post-processing device, a recording material judging section and a recording material transport controlling section. The recording material judging section judges whether the recording material used in the image forming apparatus has post-processing permissible size and thickness or not. And the recording material transport controlling section that, permits when the recording material judging section judges the recording material has the post-processing permissible size and thickness, the recording material to be transported into the post-processing device and prohibits when the recording material judging section judges the recording material does not have the post-processing permissible size and thickness, the recording material to be transported into the post-processing device.

  • GAMUT aim and GAMUT mapping method for spatially varying color lookup tables
    Patent number: 8077352
    Abstract: An image processing apparatus, program product, and method determine an achievable gamut achievable by the imaging engine or engines for all spatial locations of an output image, or all utilized print engines. A reference gamut is calculated which is any gamut containing the achievable gamut. A gamut mapping is used to map gamuts from the mean gamut to the achievable gamut, and a set of transformations is calculated for each of a set of input colors to a set of target colors selected from colors in the achievable gamut. Values for a received digital image are transformed for each image pixel or clusters of pixels based on the calculated set of transformations. Output images are generated based on the transformed values.

  • Image transfer element with balanced constant force load
    Patent number: 8075128
    Abstract: An image transfer mechanism includes a pressure element and a lever system. The lever system has a load attachment point with a range of position that depends on the thickness of a print medium positioned between the imaging element and the pressure element. A load mechanism includes a load connector with a distal end attached to the lever system load attachment point so that displacement of the lever system attachment point causes longitudinal movement of the load connector. The load mechanism applies a load that is substantially constant throughout the range of position of the lever system load attachment point. The load mechanism includes a spring and a crank attached to the spring and to the proximal end of the load connector. The crank is configured so that a change in the spring force produces a lesser change in the load force at the distal end of the load connector.
