Abstract

Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.
