Abstract: In a reproduction method for printing a hardcopy document with a highlight color printer so that the hardcopy document is printed with areas thereof printed with a selected highlight color imaging material and areas thereof printed with a black imaging material, which hardcopy documents may be subsequently optically copied as black and white copies on a black and white only optical reproduction apparatus, selected highlight color imaging materials which do not copy well on the black and white only optical reproduction apparatus are printed with a repeating optically distinguishable pattern in the highlight color printed areas of the hardcopy document with the same highlight color printer concurrently with the printing of the selected highlight color. The pattern is optically distinguishable by the black and white only document reproduction apparatus so as to automatically reproduce in the black and white copies made of the hardcopy document.

Abstract: A nonlinear operation unit includes a nonlinear function unit for receiving at least one input signal and performing a nonlinear computing operation on the input signal.

Abstract: A penta-level xerographic unit produces five exposure levels on a photoreceptor. The five exposure levels select between a subtractive and an adjacent additive primary color in both the CAD and DAD operational regimes of a xerographic process. Exposure levels intermediate between the CAD and the DAD result in white. The selection of two possible colors in CAD, or two possible colors in DAD, or the selection of no toner yields a possibility of five colors. This penta-level xerographic unit can be used for a K+3 reduced color gamut printer, typically cyan, yellow and red plus black.

The molded arm includes a hinge and the segment of the molded hinge extends outside the housing connected to the elongated arm. One end of the elongated arm engages a moving photosensitive surface and deviations of the edge position of the photosensitive surface rotate the shutter in relation to the light path between the LED and photodetector for tracking the edge position of the moving photosensitive surface by providing signals representing shutter position.

Abstract: A supply cartridge for a printer or copier retains a quantity of dry marking material. The cartridge defines a round structure on an exterior thereof, with a collar rotatable about the round structure. The round structure and the collar both define openings, and the cartridge can dispense marking material when the openings are aligned. A pad is attached to an inner surface of the collar to enhance urging of the collar against the opening of the cartridge when the cartridge is closed. The pad itself urges against the round structure at a point on the circumference of the round structure opposite the opening therein. Alternately, a protrusion can be provided in the round structure at a point opposite the opening.

Abstract: An image processing system for preparing a document for printing which receives multi separation color documents for printing, each discrete area or pixel in the image described by a signal having a number of possible states greater than can be rendered by a selected printer. In such a system, each separation of the image is separately processed with an error diffusion process which takes into account the processing of another separation, if any. Output signals from a separation are used to determine threshold values for at least one other separation. The varying thresholds are used to vary the likelihood of the current pixel being a spot or no spot.

In addition to indicating the x and y axis position coordinates of the input, the input pad of the user interface also registers a z axis coordinate based on the pressure applied by the operator on the outer surface of the input pad. This z axis force component is enabled by the force sensing layers of parallel conductors in the input pad.
