Abstract

See full text

A method for producing duplex copies from a duplex original wherein only one copy of the odd or even sides of the original documents is made during the first circulation of the originals to and from the exposure platen. During each subsequent circulation of the original documents, excluding the last circulation, two copies of the odd or even sides of the original are produced and either stored in a buffer tray if one side of the copy sheet is blank or transported to an exit tray if duplex copying has been completed on the copy sheet. Only one copy of the odd or even sides of the original documents are made during the last circulation and transfered to the blank sides of the copy sheets in the buffer tray to complete a duplex copy.
