Abstract

In high speed "racetrack" recirculating document handlers, as shown in Figure 1, a problem exists in restacking the documents 2 into the document tray 3. The document can leave the restacking corrugating rolls 4 and settle on top of the document stack in the tray 3 in an uncontrolled floating state. Lightweight documents, e.g., 9 pound paper, have a tendency to 'lflutter'' and float and take various lengths of time to settle into the load tray 3, especially larger sheet sizes such as Japanese B4. Heavier documents have a tendency to overshoot the tray front wall 5 or bounce backward and to restack in a skewed state.
