Abstract
A stripper blade assembly for an ink jet offset printer has a thin blade fixedly mounted on a top surface of a blade holder. The blade holder includes at a trailing edge flexible eyelet portions that extend downwards to snap over protuberances on mechanical connectors overmolded onto a rotatable shaft in order to secure the blade holder to the shaft. The thin blade engages the surface of an offset drum of the ink jet offset printer along the width of the drum at an appropriate point in the print process to strip the leading edge of a print medium from the offset drum surface, minimizing damage to the offset drum surface and to the printed image on the print medium while also minimizing the risk of a jam.

A stripper blade assembly for an ink jet printer having an offset drum comprising:
- a rotatable shaft;
- and
- a mechanical connector fixedly attached to the rotatable shaft;
- a blade holder including a body having a top surface, a bottom surface, and means fixedly mounted to the bottom surface for detachably attaching the body to the mechanical connector;
- and
- a thin blade fixedly mounted to the top surface of said body such that, when contacted to the drum at an appropriate point in a print process, the thin blade engages an entire leading edge of a print medium on the offset drum to strip the print medium therefrom;
- wherein the body further comprises a plurality of ribs, each having a slot, fixedly mounted on the bottom surface for interacting with the rotatable shaft when the body is attached thereto.
