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.

摘要： Systems and methods are described that facilitate reducing temperature droop during an initial portion of a print job by reducing fuser speed to increase fuser-to-paper interaction while fuser heat is absorbed by the paper during a temperature transient. For instance, during a first N pages of a print job, where N is an integer, the paper acts as a heat sink and exerts a thermal load on the fuser roll. To compensate, fuser speed is reduced initially to ensure that a given amount of heat is applied to toner on the pages. Fuser speed is increased until fuser temperature reaches steady state. Acceleration of the fuser is also adjustable.

摘要： A system that determines an amount of toner mass present on a toner application surface, and comprises a specular reflection sensor, a diffuse reflection sensor, an output combination module, and a mass determination module. The specular reflection sensor receives electromagnetic radiation that has been specularly reflected by the toner application surface, and generates a specular reflection output representative of the received electromagnetic radiation. The diffuse reflection sensor receives electromagnetic radiation that has been diffusely reflected by the toner application surface, and generates a diffuse reflection output representative of the received electromagnetic radiation. The output combination module creates a combined output by combining the specular reflection output and the diffuse reflection output with the purpose of reducing a noise source common to both specular and diffuse outputs to improve the signal to noise ratio. The mass determination module determines an amount of toner mass present on the toner application surface based on the combined output.
