ABSTRACT:
A sheet transport for a photocopier for reversing the direction of sheet travel has only an outer curved guide surface, and input, intermediate and output drive rolls spaced apart less than the length of a sheet. The disengageable output drive nip cooperates with an opposed guide surface and one or more retractable stops to achieve registration of the copy sheet with the image.
