Zusammenfassung:A method for indexing a lift plate in an image forming device according to one exemplary embodiment includes driving a motor in a first direction to drive a pick mechanism for feeding media from a stack of media sheets on a raisable lift plate such that as media is fed the height of the pick mechanism decreases. When the height of the pick mechanism falls below a predetermined level, the motor is driven a predetermined amount of rotation in a second direction opposite the first direction to raise the lift plate in order to raise the pick mechanism to a desired pick height.
