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.

Key Descriptions
&Advances the paper.
2Clears the entire pending operation except the memory or the
grand total.
>Interprets the number in the display as a percentage.
IClears an entry or an error or overflow.
(Removes the last digit entered in the display.
4Prints a reference number or date without affecting
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
.
TDisplays and prints the total, but does not clear the total.
UDisplays and prints the total and clears the total. Also resets
the item counter (
IC
) to zero.
#Calculates the selling price and profit or loss amount on an
item.
0Displays and prints the value in memory and clears the
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.
FSubtracts the displayed value from memory. If a multiplication
or division operation is pending,
F
completes it and
subtracts the result from memory.
NAdds the displayed value to memory. If a multiplication or
division operation is pending,
N
completes it and adds the
result to memory.

Printing (POWER Switch)
OFF The calculator is turned off.
ON Calculations are displayed but not printed.
PRT Calculations are displayed and printed.
IC Both the printer and item counter are active. To clear the item
counter, press
U
or
0
.
GT 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)
PResults are rounded down (if DECIMAL = 1, 2.33 rounds to 2.3).
5/4 Results are rounded up or down, depending on the value and
decimal setting (if
DECIMAL
=
2
, 2.349 rounds to 2.35).
QResults are rounded up (if DECIMAL = 1, 2.33 rounds to 2.4).
Using Decimals (DECIMAL Switch)
+Lets you add and subtract numbers without entering the decimal
point (key in 5321 to enter 53.21). Shows two decimal places.
FThe number of decimal places varies based on the result.
0,2,3,4 Sets the number of decimal places to 0, 2, 3 or 4.
Entering a Tax Rate (TAX Switch)
SET Lets you enter a tax rate to perform tax calculations.
CALC 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.

4
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
Eand 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 Eand 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.

Prise en main rapide
Installation du rouleau de papier
1. Soulevez le porte-rouleau de manière à le faire dépasser à l'arrière
de la calculatrice.
2. Raccordez le cordon d'alimentation de la calculatrice à une prise
accessible et située à proximité.
3. Positionnez le bouton POWER sur ON.
4. Insérez l'extrémité du papier dans la fente à papier située à l'arrière
de la calculatrice, comme illustré. Pour éviter des bourrages de
papier, utilisez du papier de bonne qualité.
5. En alimentant le papier dans la fente, appuyez et maintenez
enfoncé &.
6. Placez le rouleau de papier sur le porte-rouleau.
Remarque :Pour éviter d'endommager l'imprimante (ce qui pourrait
rendre la garantie caduque), positionnez le bouton POWER sur ON
lorsque vous utilisez la calculatrice sans papier.
Remplacement du rouleau encreur (IR-87T)
1. Arrachez le papier entre le rouleau de papier et la calculatrice et
appuyez ensuite sur &pour dérouler le reste de papier.
2. Positionnez le bouton POWER sur OFF.
3. Retirez le couvercle en plastique transparent du compartiment de
l'imprimante.
4. Saisissez la patte qui se trouve sur le haut du rouleau encreur rouge et
soulevez doucement le rouleau encreur de son compartiment.
