摘要： A controls system architecture for an image output terminal (IOT) has a hierarchical structure which isolates subsystem controls for purposes of efficient algorithm design, analysis and implementation. The architecture is preferably divided into three levels and has a controls supervisor which provides subsystem isolation functions and reliability assurance functions. The architecture improves image quality of IOT outputs by controlling the operation of the IOT to ensure that a toner reproduction curve of an output image matches a tone reproduction curve of an input image, despite several uncontrollable variables which change the tone reproduction curve of the output image.

摘要： An apparatus and method for maintaining tone reproduction for printing of a final halftoned image in a printer, including scanner for generating a continuous tone image. A halftoner is provided for generating pixel data based on the continuous tone image, each pixel data having pixel position parameters and desired pixel darkness parameters. A developer unit is provided for marking representative halftone targets on an imageable surface with toner. A sensor is provided for sensing an amount of toner on each of the representative halftone targets. A tone control system is provided for generating a representative tone reproduction curve based on the amount of toner sensed on the representative halftone targets. A monitoring system is provided for producing a feedback signal by comparing the representative tone reproduction curve to a setup calibration tone curve, and wherein the halftoner being responsive to the monitor system, adjusts pixel data of each pixel of the final halftone image to compensate for deviation between representative tone reproduction curve and the setup calibration tone curve during printer operation to achieve the desired tonality of the final halftone image.

摘要： A method of controlling voltages in a latent image development printer. A printer controller receives three parameters and determines a substrate charging voltage, a development station bias voltage, and a laser power for discharging the substrate, based on the three parameters. The three parameters include a difference between a substrate charging voltage and the development station bias voltage, a difference between the substrate discharging voltage and the development station bias voltage, and a ratio between the discharging voltage minus a residual voltage and the charging voltage minus the residual voltage. The ratio parameter controls the optical density of intermediate gray levels without substantially affecting other qualities of the printing process.

摘要： A printing system includes one or more printing system components positioned opposite a moving print media. A wick assembly can be attached to a printing system component to wick condensation away from a surface of the printing system component that is opposite the moving print media. A heating element can be in contact with one or both of the wick assembly and a printing system component. A protective layer can be attached to the surface of a printing system component that is opposite the moving print media to prevent condensation from forming on the component. A vacuum assembly can be positioned opposite the moving print media to produce suction over the print media that pushes humid air or some condensation into the vacuum assembly.

摘要： A method of providing calibration data for a printer includes printing a calibration target using the printer. The target includes a plurality of patch sets, each including a plurality of test patches, each patch having a respective color. Scanned patch data for one of the sets are received from a spot scanner. The scanned patch data values are compared to respective aims to determine a reproduction error value for the scanned patch set. A processor automatically determines which of the sets should be scanned next using the calculated reproduction error value. The process is repeated until all sets have been scanned, or until the reproduction error value is less than or equal to a selected threshold. Calibration data are automatically generated using the scanned patch data.

摘要： A gapless label media which can be carried by a liner or be linerless. Apparatus is also disclosed for printing on and applying resultant labels which are staggered laterally across the media width. In an embodiment of the invention, the label printer comprises a printhead for printing on the media, a sensor sensing the leading edge of each first label at a known distance from the printhead and a drive system moving the plurality of labels from a position of the sensor to a pre-established print position under the printhead. In another embodiment of the present invention, in which there may be lateral drift of the labels, the sensor senses along a path having a width greater than a maximum amount of lateral drift of the plurality of labels. Alternatively, plural sensors may be utilized to detect plural paths through the labels to detect lateral drift of the labels, or to detect alternating ones of the labels.

摘要： The present invention provides an object-oriented file structuring system. The invention provides a method of defining DATA objects and CONTAINER objects and SYSTEM objects that facilitates navigation through a file structuring system. Notation and nomenclature are defined for building files composed of CONTAINERs and DATA and SYSTEM objects and for defining relationships between and among files, CONTAINERs and DATA. A FOCUS LIST tracks objects of interest and aids in NAVIGATION. CONTAINER objects contain other objects. DATA objects enclose DATA in either machine-dependent or machine-independent value representations. Developers work with logical files and can freely create and modify the logical relationships of file objects. A RECONSTITUTION algorithm periodically updates the physical file to correspond to the logical file.

摘要： A method is provided of compensating for periodic non-uniformity in an electrophotographic (EP) printer with a rotatable imaging component, and a runout sensor for measuring the distance between a first reference point and the surface of the first component along a first reference axis. An image signal representing an image to be produced on a receiving member by the printer is received. The component is rotated. While it is rotating, the distance for the component is measured using the runout sensor. A correction value corresponding to the measured distance is automatically determined using a processor. The image data corresponding to the measured distance are automatically adjusted with the correction value using the processor. Toner corresponding to the adjusted image data is deposited on the receiver using the component.
