Abstract
Embodiments of a pick mechanism for use in an image forming device. In one embodiment, a first mechanism individually moves each of the media sheets from a stack in the input area thereby gradually decreasing a height of the stack. The first mechanism applies a first force profile to the stack while individually moving each of the plurality of media sheets. As the media sheets are moved, the height of the stack gradually decreases from a first height to a second height. As the stack decreases below the second height, a second force profile is applied to the stack. The second force profile is different from the first profile. The first and second force profiles prevent slip as the media sheets are fed from the input area, and also prevent double sheet feeds.
