REPLACING INK 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 paper roll, tearing paper at rear of 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 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.
