Abstract
The present invention provides an imaging system and method having a media stack component measuring system for identifying media characteristics. The imaging system includes a printer engine. A printer control system is in communication with the printer engine. A media holder is provided for holding a media stack including a plurality of sheets. A media stack component sensing system is provided which provides an output signal having a thickness component representative of sheet thickness of the sheets in the media stack.
