Abstract: Example embodiments relate to document alteration based on native text analysis and optical character recognition (OCR). In example embodiments, a system analyzes native text obtained from a native document to identify a text entity in the native document. At this stage, the system may use a native application interface to convert the native document to a document image and perform OCR on the document image to identify a text location of the text entity. The system may then generate an alteration box (e.g., redaction box, highlight box) at the text location in the document image to alter a presentation of the text entity.

Abstract: Methods of the present invention allow for optimization of color and shades of gray documents prior to their conversion to a monochrome format. If color/gray elements are identified in the document, the distance between them and their intensity is determined. If there are elements with the same or similar intensity in close proximity to each other, colors of some of the elements may be replaced with solid monochrome colors, and/or dithered surfaces, and/or monochrome patterns. Further, the elements may be outlined. These improvements make elements in the document more distinguishable after its conversion to a monochrome format. The described color optimization and outlining may have wide applicability in the Internet Fax technology.

Abstract: An air bearing sheet heater assembly is provided for heating a sheet in an ink imaging printer. It includes a heater plate that has a heating element and defines a first side of a sheet path through the heater assembly. It also includes at least one movable platelet that defines a second side of the sheet path, as well as, an air bearing assembly mounted to the at least one platelet. The air bearing assembly controllably creates an air bearing between the second side and the first side of the sheet path for moving and pneumatically spacing the front surface of the at least one movable platelet from the front side of the heater plate, thereby reducing stiction forces and friction along the sheet path through the air bearing sheet heater assembly.

The system further includes a removable extension strip having a front surface with an adhesive zone and a non-adhesive zone, a non-adhesive back surface, and a straight line of demarkation between the adhesive and non-adhesive zones. The adhesive zone is configured to removably adhere to the non-imaging surface, and the straight line of demarkation is configured as a placement guide for adhering the adhesive zone of the extension strip to the media. An associated method includes adhering an adhesive portion of removable extension strip to a non-imaging surface proximate a trailing edge of the media, and ink-jet printing an image on an imaging surface of the media using an ink-jet printer. The strip is used by rollers in the printer to advance the media.

Abstract: A method for reducing edge effect (white gapping) between objects formed on a photoconductive member of an imaging device includes, during processing of a given color plane, partially exposing the photoconductive member for all image data that specifies a color to be developed on at least one color plane but that specifies no color to be developed on the given color plane. As such, the partial exposing does not enable development of that image data during image processing of the given color plane. By partially exposing objects that do not include a color to be developed on the color plane currently being processed, and while normally exposing adjacent objects that include a color to be developed on the current color plane, the lateral electric field effects between the objects is reduced and, thus, toner development for the given color plane is more edge precise for reduced white gapping between the objects.

Abstract: When image areas pass the pre-transfer eraser, a control unit sets the light quantity of the pre-transfer eraser so that the potential of the background areas changes to reduce the difference from the potential of the visible image areas. A pre-transfer surface potential of the background areas in the image areas is controlled to a level that prevents the central parts of letters from missing and restrains the spread of toner in the periphery of letters. When the non-image areas pass the pre-transfer eraser, the control unit sets the light quantity of the pre-transfer eraser so as to be larger than that of the case when the image areas are exposed. Specifically, the control unit sets the light quantity of the pre-transfer eraser so that the surface potential of the non-image areas is reduced to the residual potential level of the photoreceptor surface having passed a charge removing unit.

Abstract: An imaging system is provided which combines the perfect registration capabilities of xerocolography to form perfectly registered red, green and blue images in a single pass in one mode of operation. In another mode of operation, the color gamut possible with RGB toners is extended using black toner to develop an image that is formed using a second imager or exposure device. The result is an extended gamut color imaging process using four colors side by side in a single pass with a minimum amount of color desaturation and with a minimum number of image registrations. Yet another mode of operation provides for creating K+2 colors in a single pass. The three or two colors may be used to form highlight colors and/or logo colors.
