Abstract
A method and device disclosed herein controls the movement of media sheets within an image forming device using a pick mechanism that contacts and moves a media sheet from an input area into a media path. One embodiment controls the rotational speed of the pick mechanism based on a filtered combination of a pick mechanism signal and an encoder signal. An encoder roller positioned to contact the media sheets in the input area senses the movement of the media sheet to generate the encoder signal.
