摘要： A fusing apparatus includes a fuser roll and a pressure roll which define a nip therebetween. An internal heat source is disposed within a interior of the fuser roll. An external heat source is disposed adjacent the fuser roll for heating an outer surface of the fuser roll. One or both of the internal heat source and the external heat source is controlled during a print job such that the thermal gradient across the fuser roll is adjusted. As a result, a temperature overshoot which generally occurs after the print job is finished can be reduced. The influence of subsequent jobs on the fuser roll surface temperature can also be accommodated.

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 and method for adjusting the registration of an image applied to recording media in a printer. The timing of the ejection of ink from an inkjet printhead of the printer is adjusted to maintain proper registration of a first side image to a second side image for duplex printing and y registration within a second side image printing from a first color print unit, such as magenta, to a last print unit, such as black. The location of a leading edge of the first side image deposited on a continuous web of recording media is identified and the timing of ink ejection from printhead nozzles is adjusted to align the second side image to the first side image. Adjustment of the timing of ink ejection reduces or eliminates observable registration errors.

摘要： A method for adjusting the tension of a continuous web of recording media in a printing system. The method includes identifying a tension in the continuous web and adjusting the tension in response to the amount of ink being deposited on the recording media. An offset tension value is determined, stored in memory, and used by a controller to adjust the velocity or tension of the continuous web moving through the printing system to improve the printing of images.

The method includes identifying a low frequency component of a first linear velocity of a moving web, identifying a high frequency component of a second linear velocity of the moving web, and computing a linear velocity for the moving web at a roller in a print zone with reference to the identified high frequency component of the second linear velocity and the identified low frequency component of the first linear velocity.
