Abstract
An adjustable, pivoting paper tray that enhances the feeding of a full ream of shorter than standard size paper by a feed roll from the paper tray without encountering stack normal force relief impediments includes a half ream sized adjustable backstop. The backstop has floating or articulating fingers resting on the ream of paper in the paper tray that slide downward as each sheet is feed from the paper tray. This movement of fingers allows every sheet to be fed from the sheet stack.
