Adjustable idler rollers for lateral registration

A method of registering a lateral position of a sheet moved substantially in a process direction along a transport path in a media handling assembly, a lateral direction extending perpendicular to the process direction, the method comprising:

• providing at least two nip assemblies, each nip assembly including a driven wheel and an idler roller, the driven wheel being coupled to a drive mechanism regulated by a controller and being rotatably supported about a first axis extending in the lateral direction, the idler roller cooperating with the driven wheel to engage the sheet there between, wherein the driven wheel imparts motion along the process direction to the sheet, the idler roller rotatably supported to freely rotate about a second axis;
• and
• inducing relative pivotal movement between the driven wheel and the idler roller about a third axis substantially extending through a centerline common to both the driven wheel and the idler roller, whereby the induced pivotal movement pivots the second axis of rotation between a first and second orientation while the sheet is moved along the transport path by the driven wheel with the cooperation of the idler roller, wherein in one of the first and second orientations the second axis extends parallel to the first axis and in the other of the first and second orientations the second axis extends oblique to the first axis, wherein induced pivotal movement of at least one of the at least two nip assemblies is independent from the induced pivotal movement of another of the at least two nip assemblies.
