A sheet registration mechanism for aligning a sheet moving along a substantially planar transport path relative to such transport path in a plurality of orthogonal directions (e.g., the cross-track and in-track directions and remove skew). The mechanism comprises a first roller assembly having a first urging roller mounted for rotation about an axis lying in a plane parallel to the plane of the transport path, and substantially perpendicular to the direction of sheet travel along the transport path. A second roller assembly has a second urging roller mounted for rotation about an axis lying in a plane parallel to the plane of the transport path, and substantially perpendicular to the direction of sheet travel along the transport path. A third roller assembly has a third urging roller mounted for rotation about an axis lying in a plane parallel to the plane of the transport path, and substantially perpendicular to the direction of sheet travel along the transport path. The third urging roller is also movable along its axis of rotation in a direction transverse to the transport path. A control, operatively associated respectively with the first, second and third roller assemblies, selectively controls rotation of the first and second urging rollers to align a moving sheet in a direction perpendicular to the plane of the transport path, and selectively controls rotation of the third urging roller and transverse movement of the third urging roller to respectively align such moving sheet in the direction of travel along the transport path and in the direction transverse to the transport path.
