    Abstract: A method and apparatus for non-contact measurement of a media stack in an image production device is disclosed that may include detecting the position of an unfluffed media stack, setting a desired media stack height by changing a media elevator position using a media elevator control unit based on the detected unfluffed media stack position, determining if printing and fluffing has started, wherein if it is determined that printing and fluffing has started, detecting the position of the transition between the fluffed and unfluffed portions of the media stack using the one or more sensors, determining if the position of the transition between the fluffed and unfluffed portions of the media stack is below a predetermined threshold, wherein if it is determined that the position of the transition between the fluffed and unfluffed portions of the media stack is below the predetermined threshold, setting the desired media stack height by changing the media elevator position based on the detected position of the transition between the fluffed and unfluffed portions of the media stack.

    Abstract: An apparatus that is useful for acquiring and conveying a sheet includes a plenum having an opening for coupling a vacuum source to the plenum, a slide plate having a stop member positioned proximate a drop box opening in the slide plate, and a drop box adapted to slide within the drop box opening until a portion of the drop box engages the stop member so that the drop box is slidably installed in the slide plate. The apparatus may be used in an electrostatographic printing machine to improve top sheet acquisition.
