A 3-way letterbox media diverter directs and controls media in 2 forward directions and 1 reverse direction within a printer's paper path. The letterbox design enables actuation of the diverter from a first position to a second position just as the trail edge of a sheet passes a post fuser nip. Once the diverter reaches the second position, an invert nip now controlling the sheet is reversed to thereby invert the sheet. Thus, inversion of the sheet is accomplished in a small space envelope, time to reverse direction is reduced, process speed can be reduced and additional paper guides are eliminated.
