Abstract
A method and apparatus for adjusting the height of a media stack in an image production device is disclosed. The method may include setting the height of the media stack using a default multiplier, determining if printing has started, wherein if it is determined that printing has started, measuring the thickness of media sheets in the media stack, counting the number of media sheets fed to an image production section of the image production device, determining if the media stack height is below a predetermined threshold using the one or more media stack height sensors, wherein the one or more media stack height sensors determine that the media stack height is below the predetermined threshold, calculating a next multiplier using the measured paper thickness and counted number of sheets fed, and setting the next media stack height using the calculated next multiplier.
