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.

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:
• 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.
• 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.
• The keyboard register is the area of the calculators logic that stores the value that
will immediately be used in the next calculation.
• The item count register is the area of the calculator’s logic that counts your entries
into the accumulator. Each entry is counted as one item.
• The memory register is the area of the calculator’s logic that accumulates
amounts you add to 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.
