Getting Started

Installing the Paper Roll 1. Lift the paper holder so that it extends behind the calculator. 2. Make sure the calculator is plugged into an easily accessible electrical outlet near the calculator. 3. Move the POWER switch to ON. 4. Insert the end of the paper into the paper slot on the back of the calculator as shown. To avoid paper jams, use quality bond paper.
5. While feeding the paper into the slot, press and hold &. 6. Place the paper roll on the paper holder.
Note To prevent damaging the printer (which may void the warranty), move the POWER switch to ON when operating the calculator without
paper. Replacing the Ink Roller (IR-87T) 1. Tear off the paper between the paper roll and the calculator, and then press & to run out the remaining piece of paper. 2. Move the POWER switch to OFF. 3. Remove the clear plastic printer compartment cover. 4. Grasp the tab on top of the red roller and gently lift the roller out of the compartment.
5. Lower the new red ink roller into the compartment and align the hole in the ink roller with the pin in the compartment. Press down until it snaps into place. 6. Repeat steps 4 and 5 for the black ink roller. 7. Replace the printer compartment cover and re-install the paper roll.

Key Descriptions

& 2 Advances the paper. Clears the entire pending operation except the memory or the grand total. Interprets the number in the display as a percentage. > Clears an entry or an error or overflow. I Removes the last digit entered in the display. ( Prints a reference number or date without affecting 4 calculations. Adds the stored tax rate to the value in the display. ! Subtracts the stored tax rate from the value in the display. " Pressed once, displays and prints the grand total of all totals. / Pressed twice, clears the grand total. This is active only if POWER = GT. T Displays and prints the total, but does not clear the total. Displays and prints the total and clears the total. Also resets U the item counter (IC) to zero. Calculates the selling price and profit or loss amount on an # item. Displays and prints the value in memory and clears the 0 memory. Also clears M from the display and resets the memory item count to zero. Displays and prints the subtotal in memory but does not clear ; the memory. Subtracts the displayed value from memory. If a multiplication F or division operation is pending, F completes it and subtracts the result from memory. Adds the displayed value to memory. If a multiplication or N division operation is pending, N completes it and adds the result to memory. 2

Printing (POWER Switch)

OFF ON PRT IC GT
The calculator is turned off. Calculations are displayed but not printed. Calculations are displayed and printed. Both the printer and item counter are active. To clear the item counter, press U or 0. Accumulates a running grand total of all calculations you perform until you clear the grand total. To print a grand total, press /. To clear the grand total, press / again.

Rounding (ROUND Switch)

Results are rounded down (if DECIMAL = 1, 2.33 rounds to 2.3). Results are rounded up or down, depending on the value and decimal setting (if DECIMAL = 2, 2.349 rounds to 2.35). Results are rounded up (if DECIMAL = 1, 2.33 rounds to 2.4).
Using Decimals (DECIMAL Switch)

+ F 0,2,3,4

Lets you add and subtract numbers without entering the decimal point (key in 5321 to enter 53.21). Shows two decimal places. The number of decimal places varies based on the result. Sets the number of decimal places to 0, 2, 3 or 4.
Entering a Tax Rate (TAX Switch)

SET CALC

Lets you enter a tax rate to perform tax calculations. Stores the tax rate you enter for use in calculations.
Clearing Errors and Overflows
Correcting Entry Errors If you have not pressed an operation key: To clear an incorrect entry, press I. To clear the last digit, press (. If you have pressed an operation key: To cancel an incorrect entry, press the opposite operation key. This applies only to calculations involving 9,., N, or F. 3
Error and Overflow Conditions and Indicators If you divide by zero or calculate a selling price using a margin of 100%, an error occurs. The calculator prints a row of dots and 0.* and displays E and 0. An overflow occurs if you calculate a result with too many digits for the calculator to display or print. When this occurs, the calculator: Prints a row of dots and the first 12 digits of the result with the decimal shifted 12 places to the left of its correct position. Displays E and the first 12 digits of the result with a decimal point 12 places to the left of its correct position. To clear an error or overflow, press 2. The memory is not cleared unless the error or overflow occurred in a memory calculation.

Using Memory Operations

POWER = PRT, ROUND = 5/4, DECIMAL = 2, TAX = CALC Multiplication with Memory Keys You need the total of 3 items at 10.50
and 5 items at 4.95. By using the memory keys, you will not disturb a current calculation.

Using Constants
POWER = PRT, ROUND = 5/4, DECIMAL = F, TAX = CALC Multiplying by a Constant

5 x 3 = 15

5 x 4 = 20
The first number in a multiplication problem is the constant multiplier.
