Abstract
A copier/printer apparatus capable of duplex copying includes a roller assembly that shifts a sheet laterally while maintaining longitudinal movement of the sheet. A shaft that supports drive rolls that form nips with mating idler rolls has pins that extend into helical slots within the drive rolls such that the assembly rolls in a normal movement (axially) in one mode, while being able to have axial and lateral movement in another mode.
