Replacing the Ribbon
Your calculator is shipped with a 2-color ribbon already in place. You do not need to install or change it before you
begin using the calculator. When you have been using your calculator for some time, however, the print will
gradually become faint, indicating that you should change the ribbon. To change the ribbon, follow these steps.
1. Remove the paper roll, tearing the paper at the rear of the calculator. Use the Paper Advance (↑) key to
feed the remaining paper tape through the printer. Then remove the printer cover.
2. Remove the old ribbon by pulling it upward.
3. Install the ribbon spool with the black edge up. Roll from the outside of the full spool and place the
first spool on the spindle not engaged by the lever. Thread the new ribbon along the outside of the
guides and in front of the print wheels. Switch the lever to the other side and replace the second spool.
4. Rotate the spools to take up any slack. Replace the printer cover and the paper tape.
