摘要： A sheet feeder assembly for acquiring and conveying a sheet comprises a plenum connectable to a vacuum source and having an opening facing the sheet to be conveyed, and a slide plate covering the opening. The slide plate has an acquisition surface facing the sheet to be conveyed and defining apertures in communication with the plenum. A drive mechanism is connected to the slide plate and supported within the plenum, and is operable to translate the slide plate relative to the plenum to convey the acquired sheet while maintaining the vacuum through the apertures. The drive mechanism includes a motor and eccentrically driven link connected to a carriage supporting the slide plate. The motor is coupled to a cam element that drives a flapper valve disposed between the plenum and a vacuum duct. The cam element also drives a height sensing arm supported to contact the top of the stack.

摘要： A media stack sheet media stack fluffer jet flow is provided to a first plurality of media stack sheets in a media stack. The media stack sheet media stack fluffer jet flow then is provided to a second plurality of media stack sheets in the media stack. The second plurality of media stack sheets are positioned either above or below the first plurality of media stack sheets. Also, a sequence of momentary jet flows form a media stack sheet fluffer jet flow, which is then provided to a plurality of media stack sheets in a media stack.

摘要： A sheet separating and feeding system for separating a top sheet from a stack of sheets for sheet feeding, wherein a vacuum feed head has a two dimensional array of multiple vacuum tubes for vacuum engaging the top sheet, and a control system whereby at least a portion of the multiple vacuum tubes are variably positionally controlled relative to the top sheet to engage the top sheet at different levels in a different plane than the external surfaces of the other vacuum tubes so as to provide a variable three dimensional sheet corrugation inducing surface with the multiple vacuum tubes that is variable for different sheet properties.

摘要： A compact structure and rapid method for calibrating a document scanner provides for a substantially cylindrical calibration casing having a central axis and an outer surface, with a brightness calibration section of the outer surface encompassing a portion of the circumference of the outer surface, a document width detection segment encompassing a second portion of the circumference of the outer surface, and a document backer element encompassing a third segment of the circumference of the outer surface of the casing. A driver selectively positions the casing in different rotational positions in which the different segments of the outer surface of the cylinder face the optical element of the scanner.
