    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 include 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: Embodiments described herein are directed to characterizing a media curler for a printing. Test curls can be imposed on media having input curls with known input values using a media curler to be characterized. The media curler can impose the test curls based on curler settings of the media curler. Resulting output values from an interaction between the test curls and the input curls can be measured and the curler settings can be characterized based on the known input values and the resulting output values so that the media curler can be configured to respond to incoming media having a known input curl by applying curler setting to achieve a desired output curl.

    摘要: According to aspects of the embodiments, there is provided methods and systems that incorporate a model predictive controller (MPC) in an image reproduction machine with known disturbance information. The MPC uses the control action at a current time in order to minimize the impact of an impending disturbance as well as to maximize current control performance. The impending disturbance is used by the MPC to determine an incremental change that combines steady state and transient state impact on the image reproduction machine. Disturbance such as print media type, image content type, physical dimension of the print media, weight of the print media, and print job data can be employed. Further, control of the image reproduction machine is generated in real time over a receding horizon, for the purpose of minimizing a cost function indicative of image variation, energy consumption, or the like.
