Abstract: A method for reducing image burn-in artifacts in an electrophotographic printing system, includes receiving a print job including image data for a set of pages to be printed. The pages are analyzed to determine that the image data for a sequence of pages in the print job are similar. The similar pages are printed using a pattern of lateral translations wherein the image data is laterally translated such that it is printed at a different lateral position on the printed page. The similar pages can also be printed using a pattern of page orientations including a first page orientation and a second page orientation, wherein the image data for the second page orientation is rotated 180 degrees relative to the image data for the first page orientation.

Abstract: A method for reproducing an out-of-gamut spot color includes determining a color gamut for a color printer, and specifying a spot color by color coordinates in a three-dimensional color space. A first target color is determined corresponding to a color having a minimum color difference to the specified spot color, and a second target color is determined corresponding to a color on the color gamut surface having a hue value equal to a hue value of the specified spot color. A path is defined on the color gamut surface connecting the first target color and the second target color, wherein a control parameter is used to specify a relative position along the defined path. A user interface is provided enabling a user to adjust the control parameter to specify an aim color.

Abstract: A printing system for printing on tabbed media having a plurality of tab positions. A media transport system picks the next sheet of tabbed media from a media tray. A detection system detects the tab position for the sheet of tabbed media. The detected tab position is compared to an expected tab position and if the detected tab position is different from the expected tab position then either the front end is used to supply image data to be printed on the sheet of tabbed media having the detected tab position, or the media transport system is controlled to direct the sheet of tabbed media into a waste receptacle and pick one or more additional sheets of tabbed media until the detected tab position is the same as the expected tab position.

A control parameter prediction function is provided which computes a predicted control parameter value as a function of color coordinates. The predicted control parameter value is used to determine an aim color for reproducing the spot color.

Abstract: A printing system for printing on sheets of media having a non-uniform thickness profile. A user interface is controlled to instruct the operator to load a media tray with a stack of media having a specified pattern of media orientations. A media transport system picks sequential sheets of media from the media tray. A front end supplies sequential image data having orientations in accordance with the specified pattern of media orientations. A printing module sequentially prints the supplied image data on the sheets of media in accordance with the specified pattern of media orientations.

Abstract: Message logs are created on serviceable pieces of equipment and transmitted to a centralized site where they are uploaded and inserted into a centralized database. Preferably, a digital printer that maintains message logs reporting printer page counts, jobs run, errors encountered, component replacement, maintenance performed, status and diagnostic information. Reports are created from log data from the machines in the field and are accessible from a Web Server for numerous systems. The reports can predict demand on component parts to assist in maintaining adequate inventories, provide research and development teams with insight into functions and capabilities that may be advantageous to add to new machines in the future, or report information back to the individual customer as a value-added service.

Abstract: An interlock switch access control apparatus controls access to an interlock switch (12) positioned in a cavity (14) in a housing (16). The interlock switch access control apparatus includes a plate (32) for sliding above the cavity (14) in a slot (30) in the housing (16), with the plate (32) having a plurality of apertures (38, 40). A detent (34) is positioned in a first aperture (38) of the plate (32) for fixing the position of the plate (32) in a first position over the cavity (14) to cover the interlock switch (12) to prevent access thereto. A resilient member such as a spring (48) applies a restoring force to the detent (34) to push the detent (34) toward the plate (32). The resilient member pushes the detent (34) toward and through the first aperture (38) when the plate (32) is positioned with the first aperture (38) in a longitudinal path of the detent (34).

Abstract: A support structure for a flexible boat cover includes an extensible bar supported entirely by at least one cord extending therefrom to cleats located at the bow and stern of the boat. This invention provides multiple supports spaced laterally from the centerline of the boat without any additional hardware. The cord preferably elastic, may extend over the top of the windshield to provide an inclined support structure to prevent collection of water in the boat cover. The bar is extensible to accommodate boats of various widths and to reduce its length for storage when not in use. Additionally, the bar can be supported by posts underneath to support ice and snow in colder climates during the winter.
