Abstract
A paper tray automatically adjusts to accommodate a variety of media sizes. An array of photodetectors on the support surface of the tray are masked from light by placing media in the tray. A controller determines the size of the media by monitoring which photodetectors have been masked. The controller can then direct tray guides to move to predetermined positions corresponding to the size of the media.
