Abstract
A shuttling nip set sheet inverter is for use with a digital printing system. A shuttle nip selectively rotates in a forward or reverse direction. The shuttle nip rollers are mounted for mutual revolving orbit about an orbital axis. The shuttle nip rollers are also mounted for mutual translation in the process direction. An inversion nip is disposed adjacent a main nip and downstream from the shuttle nip. A diverter gate has a first end adjacent the shuttle nip and a second end adjacent the inversion nip. In duplex operation, the media sheet lead edge will pass through the shuttle nip. The shuttle nip will revolve orbitally and translate downstream. The trail edge will become the lead edge, inverting the media sheet, which enters the main nip. The diverter gate moves from an inversion position to a storage position away from the process path.
