  • 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.

  • Patent number: 8077966
    Abstract: A binarizing device includes: a difference vector calculation unit that calculates a difference vector between an average color in a peripheral pixel region and a current color of a current pixel; a selection unit that selects one of the average color and the current color as a significant color; and an output unit that, in a case where predetermined conditions are satisfied, outputs one of binary values, and that, in a case where at least one of the predetermined conditions is not satisfied, outputs the other of the binary values, wherein the selection unit calculates a run length of each of the average color and the current color in a plurality of directions in the peripheral pixel region, and selects one of the average color and the current color, which has a shorter run length, as the significant color.

  • Patent number: 8077349
    Abstract: An image processing apparatus includes an image data input unit, a density variation detection unit and a position/size detection unit. The image data input unit inputs image data containing original image data obtained by reading an original. The density variation detection unit detects density variation from the image data input through the image data input unit. The position/size detection unit detects a position or a size of the original image data in the image data based on the density variation detected by the density variation detection unit.

  • Patent number: 8077358
    Abstract: This invention generally relates to systems and methods for implementing use of customer documents in maintaining Image Quality (IQ)/Image Quality Consistency (IQC) of printing devices. The system may include an image analyzer configured to analyze input image data for a document and to identify one or more relevant pages of the document that may provide information regarding the state of the printing system; a scheduler that selects the relevant pages for printing out-of-order; a marking engine constructed to print images; a scanning device for scanning print images of the one or more relevant pages; and a buffer for holding the print images of the one or more relevant pages and inserting the print images of the one or more relevant pages into the media path in proper order. A method for analyzing printed documents is also provided.

  • 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.

  • 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.
