  • Patent number: 7762552
    Abstract: The present application is directed to devices and methods for directing media sheets moving along a media path within an image forming apparatus. In one embodiment, a gate is positioned in proximity to the media path. The gate may include an elongated shape that extends across at least a section of the media path. A fluid damper may be operatively connected to the gate and may include a shaft and a chamber that holds fluid. The shaft is rotationally positioned with a first section within the chamber and a second section extending outward from the chamber. Rotation of the shaft in a first direction may force the fluid within the chamber to move relative to the body and cause the gate to move to a first position in the media path to direct the media sheets towards a first part of the media path.
