4. Make sure the tray is not overfilled. If it is, remove the entire stack of paper from the tray,
straighten the stack, and then return some of the paper to the tray.
5. Make sure the paper guides in the tray are adjusted correctly for the size of paper. Adjust the
guides so they are touching the paper stack without bending it.
6. Make sure that the tray is fully inserted in the product.
7. If you are printing on heavy, embossed, or perforated paper, use Tray 1, the multi-purpose tray on
the left side of the printer, and then feed sheets manually one at a time.
