Accurate sheet leading edge registration system and method including a first and second nip assembly, a first sheet leading edge sensor and a controller. The first and second nip assemblies being spaced apart from one another. The first sheet leading edge sensor capable of detecting an arrival of a leading edge of a sheet at a point in the process direction. The arrival being associated with engagement of the first and second nip assemblies with the sheet. The controller capable of imparting a rotational skew velocity to the sheet using the first and second nip assemblies. A center of rotation of the skew velocity being offset laterally from a center of the sheet leading edge. The method includes providing at least the above-mentioned nip assemblies, first sheet leading edge sensor and controller.
A system for registering the leading edge of a sheet moved substantially in a process direction along a path in a media handling assembly, a lateral direction extending perpendicular to the process direction, the system comprising:
