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.

Keyboard Layout

This section describes the mode switches, data entry keys, and operating keys provided on your calculator. The
following terms are used in discussing your calculator’s operation:

¾ The accumulator is the area of the calculator’s logic that stores a running total of the results of addition

and subtraction operations. It is the “adding machine” portion of the calculator.

¾ The calculating register is the area of the calculator’s logic where the intermediate and final results of

multiplication, division, and percentage calculations are stored. The contents of the calculating register do
not affect the accumulator.

¾ The keyboard register is the area of the calculator’s logic that stores the value that will immediately be

used in the next calculation.

¾ The item count register is the area of the calculator’s logic that counts your entries into the accumulator.

Each positive or negative entry is counted as one item.

¾ The memory register is the area of the calculator’s logic that accumulates amounts you add or subtract

from the memory. Because the memory register is independent of the accumulator and the calculating
register, it retains its value until you clear it with the Memory Total (MT) key.
