Claim:
A printing system comprising: a marking engine and a document transport highway path; an inverter including an input path and selectively reversing inverter rollers whereby selected ones of media sheets move from said transport highway path through said input path; said selectively reversing inverter rollers include a first drive nip assembly and at least a second drive nip assembly, said first drive nip assembly driven at a first velocity and said second drive nip assembly driven at a second velocity; said first velocity different from said second velocity so as to deskew a media sheet simultaneously as said media sheet enters and exits said inverter; and, said inverter further includes a first output path, said first output path having a return path whereby said selected ones of media sheets move in a forward direction through said input path and non-inverted in same said forward direction through said first output path and said return path to said transport highway path.
