Abstract

PURPOSE:To conduct compensatory copying rapidly even in jamming in copying the second original, by starting to copy the second original on the other paper after having copied the second original on the second faces of the copying papers with the first original already copied on their first faces left on the relay tray for both face copying. CONSTITUTION:Originals O fed on platen 6 are copied on both sides of papers S. Each paper S is fed from cassette feeder 24 or pile feeder 25 to transfer section 26 to transfer a toner image on electrostatic drum 16 and feed the paper to fixing section 29. In both face copying, paper S is fed to inverted paper route 46 with inverting guide 38, and sent to relay tray 23 via routes 52, 53. Paper S with the developed image of second original is sent agent to transfer section 26. At that time, if trouble such as paper jam occurs, the second original is successively copied on the relaid papers, and then, fresh papers are fed by a deficient number to copy the second original, and fed to tray 23 to copy the first original on the other faces of them.
