    • According to aspects illustrated herein, a method, a system, and a printmaking device for performing closed loop lateral and skew control of a sheet is provided. The printmaking device includes a feed path, printing module, and sheet registration system. First, the feed path moves the sheet in a process direction past the lateral sensor. Next, the sheet is registered by measuring a lateral position of one side edge of the sheet at a fixed reference using the lateral sensor and determining a lateral position error of the sheet using the lateral position measurement. After that, a sheet angular velocity is calculated based on the lateral position error using the registration controller. Then, the lateral position error is corrected using the at least one pair of registration nips to adjust the sheet by applying the sheet angular velocity to the sheet.

    • A sheet handling system comprising a sheet registration system having sheet registration nips and a receiving system for a sheet including a capturing point for engaging said sheet. Auxiliary nips are positioned between the sheet registration nips and the receiving station. The auxiliary nips are moveable between an open and closed position. A controller receives a signal indicative of the length of the sheet and sends a signal to the auxiliary nips to be in a sheet engaging position when the length of the sheet is less than the distance between the sheet feeding nips and the capturing point of the receiving station and be in an open position if the length of the sheet is greater than the distance between the sheet registration nips and the capturing point of the receiving station. In another embodiment, the auxiliary nips are maintained in their open position until the trailing edge of a sheet is about to leave the sheet registration nips, at which point the auxiliary nips are closed.

    • 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.
