Abstract:
1. An apparatus for 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 apparatus comprising: a sheet registration nip assembly for changing characteristics of the sheet with respect to the transport path, the characteristics of the sheet including at least one of a skew position, process direction position and a lateral position of the sheet, the sheet registration nip assembly changing a first sheet characteristic to a first target characteristic by the time the sheet reaches a preliminary registration datum, a delivery registration datum being disposed downstream of the sheet registration nip assembly, the sheet registration nip assembly changing a second sheet characteristic to a second target characteristic when at least a portion of the sheet is disposed along the transport path between the preliminary registration datum and the delivery registration datum; an auxiliary nip assembly disposed between the delivery registration datum and the sheet registration nip assembly, wherein the preliminary registration datum is disposed between the delivery registration datum and the auxiliary nip assembly an element biasing the auxiliary nip assembly selectively into one of an open and a closed position; a first sensor measuring the first sheet characteristic at a first point along the transport path, the first sensor emitting a first signal; and a second sensor measuring the second sheet characteristic at a second point along the transport path, wherein a second signal from one of the first and second sensors indicates a length of the sheet exceeds a predetermined value.
