Abstract: Systems and methods are provided that improve the registration between the color separation images. The systems and methods control the output of the image data for one or more of the color separation images and the velocity of an image-carrying member to remove or reduce registration offsets based on determined position and velocity of the image-carrying member. A position-determining sensor on an image-carrying member device module is used to determine the process-direction position of the image-carrying member to provide real time motion information by simultaneously sensing a plurality of position-determining marks. A position-determining controller determines the process-direction position of the image-carrying member by detecting the plurality of position-determining marks using the position-determining sensor and averaging or correlating the detected data.
