ABSTRACT:
A copier capable of producing simplex and duplex copies includes a tri-roll inverter that employs a corrugation roll on roll return force applicator located downstream of and off line from the input nip of the tri-roll input/output members. A sheet driven by the input nip into the inverter is corrugated as it penetrates the roll on roll return force applicator nip. When the last portion of the sheet is driven into the return force applicator nip, the friction return force of the nip will cause the sheet to drive into a foam roll which delivers the sheet to the output nip.
