摘要： A dual mode imaging device includes an input for supplying a medium to the imaging device, the medium comprising at least one of an erasable paper, and a non-erasable paper. The erasable paper can be one of an imaged or a non-imaged erasable paper. A conventional imaging subsystem is provided for imaging the non-erasable paper. A heating subsystem is provided for heating an input medium to one of an erasing temperature, an imaging temperature, or a fusing temperature according to a type of job requirement. A cooling station selectively cools an erased medium to an imaging temperature. A write subsystem is provided for UV imaging an erased medium.

摘要： A printing apparatus or printing system that uses multiple print engines to form an image on a substrate. The printing apparatus or printing system may be a surface printing system or a reverse printing system. Each of the multiple print engines has at least one color station. The color stations are arranged in the print engines and between the multiple print engines based on whether the printing system is a surface printing system or a reverse printing system to control the order in which colorant is formed on a substrate. Multiple print engines allow for, among other things, a greater color gamut and therefore assists in expansion of the standard color gamut.
摘要翻译：一种使用多个打印引擎在基板上形成图像的打印设备或打印系统。打印设备或打印系统可以是表面印刷系统或反向印刷系统。多个打印引擎中的每一个具有至少一个色站。基于打印系统是表面印刷系统还是用于控制在基板上形成着色剂的顺序的反转印刷系统，将色站布置在打印引擎中并在多个打印引擎之间。多个打印引擎除其他外允许更大的色域，从而有助于扩展标准色域。

摘要： In an image rendering system, a method of compensating for system performance changes related to image attributes includes rendering a diagnostic image, sensing at least one image quality from the diagnostic image, updating an image attribute compensation tone reproduction curve based on the sensed image quality and rendering an image based on the updated image attribute compensation tone reproduction curve. For example, image attributes include print media type and a halftone screen selection. An image processing system operative to perform the method of compensation includes a set of image attribute compensation tone reproduction curves. Each curve of the set is associated with a particular combination of image attributes. For example, each curve is associated with a particular media type/halftone screen combination.

摘要： A secure document processing system for receiving an original document and for printing a secure hardcopy version of the original document, wherein the secure hardcopy version includes a machine-readable encoded image signature which represents an image segment of the original document. Such hardcopy secure documents can be validated by inputting them to an secure document validation system operable to identify and process the machine readable encoded representation and in response to determine whether the recovered image signature indicates that the document is counterfeit or has been altered.

摘要： A method and apparatus for overloading operators in Page Description Language (PDL) defined graphics adjusts widths of lines in a manner that yields preferred line widths, such as to compensate for certain undesirable line growth characteristics of a target printer or display device. Line width can be controlled based on various attributes, such as color, size, width, pattern or orientation. Line width can be redefined to be wider, narrower or of a differing color to achieve a desired printed graphic. The method, performed within a decomposer, examines individual lines of a PDL defined graphic, determines if compensation is needed to achieve a desired printed output, and redefines a modification attribute to achieve the compensation.

摘要： A color electrophotographic printing machine in which latent images having a resolution of at least 1.44 million pixels per square inch are recorded on a photoconductive member. Different color toner powder images are developed in superimposed registration with one another to form a composite multicolor image. The composite multicolor image is transferred from the photoconductive member to a receiving member. Toner particles which have a selected pigmentation and small volume average diameters are used to minimize curl of the receiving member.

摘要： An apparatus in which contaminants are on-the-fly removed from an electrode wire positioned between a donor roller and a photoconductive surface. A magnetic roller is adapted to transport developer material to the donor roller. The electrode wire is electrostatically biased with respect to the donor roller to remove contaminants therefrom. The electrostatic wire bias polarity corresponds with the contaminant charge polarity to repel the contaminants from the wire.
