Each of the first plurality of local color plane correction values corresponds to one of the first plurality of color registration errors. A second copy of the print job is printed using the local color plane correction values for each document in the print job.

Abstract: A method of detecting an RFID tag includes transmitting a bait RFID read signal at a bait power level and a simulated response signal at a simulated-response power level. A selected reader frequency is monitored for a selected detection time. A skimmer is determined to be present if a skimmer RFID read signal is detected during that time. If a skimmer is not determined to be present, multiple read signals are transmitted sequentially, each signal at a respective read power level. At least one of the read power levels is lower than the bait power level, at least one of the read power levels is lower than the simulated-response power level, and at least two of the read power levels are different from each other. A selected response frequency for a tag is monitored for a response from an RFID tag.

Abstract: A method of verifying the identification of fluids to be supplied successively through a fluid-supply hose that selectively connects to successive movable, RFID-tagged fluid containers includes providing an RFID reading unit including an antenna. A sequence of reference container identification codes is received. A container-present indication indicating one of the containers is positioned so that its RFID tag is in the antenna range is received. In response, the RFID tag of that container is read using the RFID reading unit to determine an identification code of the container. A controller automatically verifies the determined container identification code against the first reference identification code in the sequence using a controller. The starting through verifying steps are repeated, using successive values from the sequence in the verifying step, until all values in the sequence have been verified against container identification codes read using the RFID reading unit.

Abstract: A media diverter system for directing a media sheet traveling along an input media path into either a first media path or a second media path. One or more roller assemblies are provided including a media-guiding roller having one or more grooves formed around the exterior surface, and an air source for selectively providing an air flow into one or more of the grooves, the air flow being directed between the media sheet and the exterior surface of the media-guiding roller thereby producing a Bernoulli force to draw the media sheet toward the media-guiding roller. A controller selectively activates the air source in at least one of the roller assemblies while the corresponding media-guiding roller rotates around its roller axis to draw the media sheet toward the exterior surface of the media-guiding roller, thereby directing the media sheet into either the first media path or a second media path.

Abstract: A printing system includes a plurality of imaging systems for capturing images of a receiver medium. An illumination system illuminates the receiver medium with an illumination pattern, thereby providing a reflected illumination pattern and a transmitted illumination pattern. A first imaging system is positioned to capture a first image of a first side of the receiver medium including the reflected illumination pattern, and a second imaging system is positioned to capture a second image of an opposing second side of the receiver medium including the transmitted illumination pattern. The first and second images are analyzed to determine a relative position of the reflected illumination pattern in the first image and the transmitted illumination pattern in the second image. Imaging system alignment parameters for use in aligning images captured with the first and second imaging systems are determined responsive to the determined relative position.
