Abstract

Improved document handling for a xerographic copier with automatic ejection of documents from a full size conventional document copying platen is provided for a vacuum belt document handling system in a platen cover unit. A pivotal system is disclosed for limited lifting of the exit side of the vacuum belt system away from the platen for document ejection. The document ejection path includes a belt overlying, but extending beyond, the vacuum belt to improve stripping and an opposing air jet system for overcoming the effects of the reverse air flow caused by the vacuum belt system and the closely adjacent air impervious platen.
