  • Patent number: 6619656
    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.

  • Patent number: 6565080
    Abstract: An imaging media tray includes at least one adjustable guide operatively connected to an interior surface of the imaging media tray. The guide divides the interior of the tray into a loading section and an unused section. A blocking mechanism is secured in the unused section of the media tray to prevent a user of the tray from loading imaging media into the unused section of the tray. The blocking mechanism can be provided as an adjustable blocking element with a an expandable and contractible mechanical blocker connected between the at least one adjustable guide and an interior wall of the tray. Illustrated embodiments show the blocker as a telescoping member and as a pivoting cross member arrangement.
