Abstract:
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 and being coincident with a lateral position of a virtual point, the virtual point lateral position being offset from a lateral position of the first sheet leading edge sensor.
