摘要： Methods and devices detect a first lateral measure of an edge of a belt loop supported by rollers within an apparatus using a first sensor to find an amount of misalignment of the edge of the belt loop relative to a known alignment position. The first sensor is positioned at a first location within the apparatus. The methods and devices also detect a second lateral measure of the edge of the belt loop within the apparatus relative to the known alignment position using a second sensor. The second sensor is positioned at a second location within the apparatus that is different than the first location. The methods and devices use a processor to determine the non-linear shape of the edge of the belt loop based on the second lateral measure of the edge of the belt loop detected by the second sensor. The methods and devices correct the amount of misalignment detected by the first sensor based on the non-linear shape of the edge of the belt loop to generate a corrected misalignment value, using the processor. Further, the method and devices adjust the current lateral position of the belt loop within the apparatus relative to the known alignment position based on the corrected misalignment value using a belt tracking actuator that is operatively connected to the processor.

摘要： A method of adjusting the operation of printheads in a printing system with a moving sheet carrying device has been developed. The method includes identifying a first amount of sheet carrying device displacement and second amount of sheet carrying device displacement as the sheet carrying device carries a media sheet past first and second printheads, respectively, for imaging of a predetermined location of the media sheet. A time for operating the second printhead is adjusted based on a difference between the first sheet carrying device offset and the second sheet carrying device offset to provide color registration between ink drops of the first printhead and second printhead on the media sheet.

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 includes 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 includes 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.
