Abstract

A sheet lateral registration system, especially for high speed printer print media, which can also provide sheet deskewing as well as lateral sheet registration, having substantially increased lateral translation movement re-centering time for the lateral sheet registration system by utilizing at least two lateral shifting rollers having at least two different radii which provide automatic nip closings and openings in their rotations (relative to opposing idlers), with larger radius circumferential lengths coordinated to the downstream distance of the subsequent sheet acquisition system. Additionally disclosed are coordinated position non-slip sheet feeding nips which may be positioned in the paper path between these dual radius deskewing and lateral registration rollers and the image transfer station of the printer.
