HP 4SI Not Reading Out of Paper

When the paper trays on my 4SI run out of paper, the control panel still reads READY. This is happening with both trays. When I remove a tray, I get the correct information, UC/LC Tray Empty. When the upper tray is empty, the printer tries to feed from it causing a jam. I have to remove it so the printer will default to the lower tray.
Sense this is common to both trays, I am assuming its a problem with a board. Any Ideas?
