Abstract
A printer capable of producing simplex and duplex copies includes a tri-roller inverter that employs a passive deflector gate downstream from input and output nips of the tri-roller inverter. A sheet driven by the input nip into a reversing chute of the inverter deflects the passive deflector gate to an open position that allows the sheet to enter the inversion chute and after the sheet is past the gate it returns to close deposition, thus allowing the sheet to be driven past it in reverse by a reversing roller. Once the lead edge of the reversed sheet passes the passive deflector gate, a second sheet enters the input nip resulting in two sheets being in the inverter at the same time.
