    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： An imaging device for producing multicolor images from image data containing data representing an image of a first color and an image of a second color to be registered relative to the image of the first color onto a substrate by transferring toner of the first and second colors to the substrate is provided. The imaging device comprises a first imager, a second imager, a photoreceptor belt, a plurality of rollers mounted to a frame of the imaging device, an angular position sensor, an image data source and a controller. The plurality of rollers define a process path along which the photoreceptor belt is driven past the first and second imagers in a process direction. The plurality of rollers comprises a drive roller that exhibits an eccentricity for which a formula relating angular position as a function of the phase angle of the drive roller to eccentricity is known. The angular position sensor detects the phase angle of the drive roller. The image data source generates image data that includes a line to be printed in the first color and in the second color. The controller is coupled to receive signals from the angular position sensor, ROS imager and image data source and is configured to drive the second imager to generate an optical output. The controller includes memory and a processor. The memory stores the formula relating angular position as a function of the phase angle of the drive roller to eccentricity. The processor calculates an appropriate time delay for starting the generation of the optical output of the second imager for printing the line to be printed in the first color and in the second color based on the time of the starting of the optical output by the ROS imager to print to print that line, the signal received from the angular position sensor, and the formula relating angular position as a function of the phase angle of the drive roller to eccentricity.

    摘要： A method for improving color-to-color registration in a printing device. The method includes printing a plurality of multi-color images, measuring the relative locations of a first portion of each multi-color image having a first color of each image and a second portion of each multi-color image having a second color of each image, for each image, comparing at least one difference between the first portion's location and the second portion's location with at least one desired difference between the first portion's location and the second portion's location to generate a list of positional errors, using a least square regression analysis of the list of positional errors to determine shift amounts required for placement of each first portion in subsequently generated images to within a desired degree of accuracy, and adjusting the placement of the first portion of each subsequently generated image by the determined shift amounts.

    摘要： A registration and measurement system for a printing machine includes two drive rollers and two opposing idler rollers. Each drive roller and idle roller combination respectively form a drive nip. A single servo or stepper motor is operably connected to the drive rollers through a gear train, allowing the motor to drive the sheet feeding nips. A rotary encoder is attached to each idler roller. Optical sensors are provided above a desired sheet path. The optical sensors and the rotary encoders are connected to a controller and are operable to deliver output signals to the controller. The controller is operable to determine the length of a sheet passing through the nips based upon the signals received from the optical sensors and the rotary encoders.

    摘要： In a system of automatic deskewing and registration of print media sheets moving in a printer paper path with laterally spaced apart differentially driven rollers controlled by the sensing of the moving sheet lead edge skew at a position downstream in said paper path there is further provided a subsequent trail edge sheet skew detection of the same moving sheet at a position upstream of the differentially driven rollers to subsequently differently control the differential driving of those same rollers to make a final and normally much smaller deskewing correction in the same sheet after the majority but less than all of said sheet is downstream of the differentially driven drive rollers.
