Abstract:
1. An apparatus for laterally registering a sheet moved in a process direction along a transport path in a media handling assembly, a lateral direction extending perpendicular to the process direction, the assembly comprising: at least two nip assemblies spaced apart from one another along a first axis extending in the lateral direction, each nip assembly including a driven wheel and an idler roller, the driven wheel rotatably supported about the first axis, the idler roller cooperating with the driven wheel to engage the sheet there between, the idler roller rotatably supported about a second axis, the second axis being selectively moveable, the selective movement being between a first and second orientation while the sheet is moved along the transport path by the driven wheel and the idler roller, a differential drive system operatively connected to the driven wheels of at least two nip assemblies, the differential drive system imparting different rotational velocities to each driven wheel, wherein in the first orientation the second axis extends parallel to the first axis, wherein in the second orientation the second axis extends at an oblique angle to the first axis, the selective movement pivoting about a third axis substantially extending through a centerline common to both the driven wheel and the idler roller of each nip assembly.
