Abstract:
1. A method for improving image on paper registration in an image printing system, the method comprising: advancing a target media along a media path; placing a plurality of registration marks adjacent to a toner image on an image bearing surface moving in a process direction, wherein the toner image is configured to be transferred to the target media; detecting positions of the registration marks using one or more sensors adjacent the image bearing surface; determining a correction function using the positions of the registration marks to compensate for an error in a registration of the toner image and the target media; adjusting the advancement of the target media based on the correction function, wherein the adjusting comprises adjusting target media velocity parameter of the image printing system and adjusting alignment of the target media relative to the toner image and transferring the toner image to the target media, wherein the adjusting the alignment of the target media changes angularity, offset, or both of the target media.
