    When you do this, the paper rollers move forward to help eject the jammed paper.
  2. If this does not work, press and hold down Select/Resume again.
  3. The paper rollers move in reverse.
  4. If the paper is still jammed, repeat steps 1 and 2 to move the paper rollers forward and backward.
  5. Gently remove the paper.
  6. If all else fails, remove the paper tray by pinching together the two levers under the paper tray. Pull the tray toward you, and gently remove the jammed paper. Then slide the paper tray back into the copier.
  7. Turn the copier off, and then on again to continue copying.
