    摘要： Spot color tables, or spot color emulation colorant recipes are updated using information generated during a first and second process color related system calibration. Rather than separately calibrate, through trial and error, individual spot color emulation colorant recipes, information from the first and second general system calibrations is used to adjust spot color recipes. In one embodiment, processing an existing or initial spot color recipe through both a first system model and a second system model generates a device independent color difference. A colorant difference is then determined by transforming a predicted color difference according to estimated partial derivatives of aspects of the second system model, wherein the partial derivatives relate changes in colorant amounts to changes in parameter values of a machine independent color space.

    摘要： A method to form a seven-color CMYKRGB or eight-color CMYKRGBW image having reduced toner pile height than in conventional four-color xerography, resulting in more uniform image gloss. The method includes the steps of: forming first spot next to spot toner images by placing spots of toner of a first color next to spots of toner of a second color on a first photoconductive member; forming second spot next to spot toner images by placing spots of toner of a third color next to spots of toner of a four color a second photoconductive member, and transferring said first and second spot next to spot images to form a composite spot next to spot image on an intermediate imaging member.

    摘要： A release agent management (RAM) system incorporated in an electrophotograpic printing machine having a heat and pressure fuser assembly to aid in the removal of fused copies from the fuser roll. The fuser assembly includes a heated fuser roll, a pressure roll, a sump containing a quantity of release agent, a pair of metering rolls and a donor roll. Each of the metering rolls is immersed in a quantity of release agent and is able to selectively be brought into contact with the donor roll. The donor roll acts as the transport to transfer release agent from either or both of the metering rolls to the heated fuser roll. The dual roll metering system provides a RAM system which can uniformly provide two or more oiling rates varying with the process speed of the printing machine. It also provides a RAM system which can switch oiling rates without creating oil slugs which ultimately reach the fuser thereby degrading copy quality.

    摘要： A method for determining a response to misalignment of a camera monitoring a desired area includes acquiring temporal related frames from the camera including a reference frame. A pixel location is determined of a reference object from the frames. Using the pixel location of the reference object, a displacement of the camera between a current frame and the reference frame is determined. For the displacement exceeding a first threshold, a new displacement of the camera is measured by introducing at least one additional object to a camera field of view and comparing the new displacement to a second threshold. For the new displacement not exceeding the second threshold, the camera is recalibrated using a determined pixel location and a physical location of the at least one additional object. For the new displacement exceeding the second threshold, notification is provided of a misalignment to an associated user device.
