摘要： An indirect media flatness measurement system, and method, by which the appropriate level of hold-down force may be determined with some degree of quantitative accuracy. In an ink jet printer that is operative to subject a substrate media to a hold down force during printing, the method including printing a predetermined test image having a predetermined pattern on a substrate media using an ink jet print apparatus to produce a test print. Optionally, pattern may be an array of test symbols. The test symbol may comprise a line printed on the substrate media in a direction perpendicular to a process direction of the printer. The test print is compared with the predetermined test image, including measuring drop placement errors of test symbols. The height of the substrate media at the location of each test symbol is calculated based upon the drop placement error.

摘要： What is disclosed is a novel system and method for xerographic Dmax control based upon measurements made on the printed paper using an inline spectrophotometer (ILS) or similar device. The disclosed method is based upon directly measuring the color to actuator sensitivity. Each of the separations is controlled independently using an actuator specific to that color separation. The present method is effective at controlling the color of the solid primaries. The fact that the vector of change is highly correlated with solid color variation seen in the field suggests that the teachings hereof effectively increase the solid color stability. Increased solid color stability increases the color stability throughout the printer gamut and the stability of the gamut boundaries, which increases the robustness of gamut mapping algorithms. Advantageously, the present method can be combined with existing ILS-based maintenance architectures.

摘要： A method and system for performing sheet registration are disclosed. Output values for a sheet may be identified within a reference frame. A difference between each output value and a corresponding desired output value may be determined. Input values may be determined based on at least the differences. State feedback values may be determined based on information received from one or more sensors. Jerk values may be determined for multiple drive rolls based on the input values and the state feedback values. A desired angular velocity for each drive roll may be determined based on the corresponding jerk value. A motor voltage may be determined for each drive roll that tracks an observed angular velocity value to the desired angular velocity value. The jerk values may create a linear differential relationship between the input values and the output values. The steps may be performed multiple times.

摘要： A system and method of aligning a sheet in a printing device are disclosed. A sheet may be received by a device having a plurality of drive rolls. Each drive roll may have a velocity associated with it. A desired trajectory may be identified and a current position may be identified for the sheet. The velocity of at least one drive roll may be adjusted based on the current position and the desired trajectory. The determining and adjusting operations may be repeated a plurality of times so that the sheet moves along the desired trajectory.
