    摘要: A closed loop feedback method that continuously adjusts the lateral and skew position of a sheet includes a first sensor that is used to measure lateral sheet edge position. A second sensor measures the lateral sheet edge position at a certain distance from the first sensor. Sheet skew values can thus be calculated. Lateral and skew controllers provide outputs to lateral and skew actuators, respectively, to adjust the sheet position. A different method of registering sheets laterally and in skew enables active sheet deskew without translating the sheet in the cross-process direction. A sensor carriage position is controlled to find the sheet edge after which deskew control can start. The average value of the carriage position can then be fed in a feedforward manner to move the image location to match the average paper position. This achieves good average lateral registration and active skew control at a reduced cost.

    摘要: Embodiments herein measure current/voltage levels of a drive motor when media is in contact with a drive roller so as to determine the drive force imparted by the drive rollers on the media. Then, embodiments herein can reference the predetermined relationship between roller drive force and media/drive roller velocity ratios to determine a difference between the velocity of the drive roller and the velocity the media based on the drive force. Once this velocity difference is determined, embodiments herein can change the current/voltage levels being applied to the drive motor if the actual velocity of the media is different than the intended velocity of the media so as to correct the velocity of the media. Thus, when referencing the predetermined relationship, embodiments herein produce a velocity ratio correction factor. This velocity ratio correction factor can be applied continuously during any velocity profile of the drive motor, or it can be used to calculate the accumulated error in sheet position and then to apply a correction near the end of the velocity profile.

    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: A control system and method for a sheet registration device including a general unit which determines desired contact point velocities for moving a sheet along a reference trajectory. The contact point velocity determination is independent of the sheet registration device. A specific unit is operably connected to the general unit. The specific unit determines registration device specific operating parameters for controlling registration device actuators to move the sheet along the reference trajectory.

    摘要: A method of controlling the average sheet velocities in the separate paths in a parallel architecture to prevent sheet collision and provide for sheet arrival in the proper order at the sheet merger point(s) in the media path. Modifying the travel time of the sheets, or re-phasing strategy, at various points along the media path ensure that sheet collision is avoided even at maximum capacity. Adjusting the velocity of the sheets allow for the printer to run at maximum capacity without jamming and collision of the sheets running therethrough.
