Abstract:
1. A printing system comprising: a marking engine and a document transport path highway; an inverter including a registration system having a pair of independently driven reversing inverter rollers; said registration system includes a translating frame for translating said reversing inverter rollers wherein said inverter rollers are differentially driven while being translated by said translating frame for inverting and registering a document along a media path; sensors for sensing if the document is skewed and laterally offset during ingress of the document to the inverter and during egress of the document from the inverter; and, wherein said pair of reversing inverter rollers include at least two drive nip assemblies that are driven in forward and reverse directions with differential velocities so as to deskew and invert the document simultaneously while said drive nip assemblies are translated to register the document in a cross process direction.
