The display will show the remaining funds. Press the eject button to retrieve your card. The card reader may automatically eject the card if there is less than 9 cents left since there are not enough funds to pay for one sheet of paper. Make sure the printer LCD display reads Ready before proceeding. The message Tray 1 empty does not mean that the printer is out of paper.
Most printers have more than one input tray.
If you see a message, Tray 3 empty, contact the Computing Help Center. Check that the screen displays the Insert card logo. If not, press the Escape or Esc key on the keyboard. Insert your photocopy card in the reader. Make sure that you pushed the card in as far as possible and it is locked in position.
