1. In a reproduction machine which feeds imaged copy sheets to an output tray, the improvement of a skew offset correction device for removing skew in sheets en route to the output tray, comprising:

  • a tapered drive roll;

    an axially adjustable idler roll that makes line contact with said tapered drive roll to form a nip therewith; and

    means for adjusting said idler roll axially along an outer surface of said tapered drive roll in either of two directions such that adjustment of said idler roll in a first direction with respect to the surface of said tapered drive roll causes a sheet driven through said nip to skew in a first direction and adjustment of said idler roll in a second direction with respect to the surface of said tapered drive roll causes a sheet driven through said nip to skew in a second and opposite direction.
