OPERATIONAL NOTES

To insure trouble-free operation of your SHARP
calculator, we recommend the following:

1. The calculator should be kept in areas free from
extreme temperature changes, moisture, and
dust.

2. A soft, dry cloth should be used to clean the
calculator. Do not use solvents or a wet cloth.

3. Since this product is not waterproof, do not use it
or store it where fluids, for example water, can
splash onto it. Raindrops, water spray, juice,
coffee, steam, perspiration, etc. will also cause
malfunction.

4. If service should be required, use only a SHARP
servicing dealer, a SHARP approved service
facility or SHARP repair service.

5. If the unit is operated from AC power only, without
installing the memory protection battery, the set
tax rates and memory contents (including GT
memory) will be cleared if the power plug is
removed from the outlet. This will also occur when
the memory protection battery is replaced.

INSTALLING OF BATTERY FOR MEMORY PROTECTION

Before using for the first time, remove the attached
lithium battery, and install it in the equipment
according to the following procedure.
If the power cord is unplugged by accident when
operating with AC power only, the set tax rate and
the contents of memory will be lost.

1) Turn the power switch “OFF” and unplug the
power supply plug from the outlet.

2) Remove the battery cover on the back of the unit.
(Fig. 1)

3) Wipe the battery well with a dry cloth and place
the plus “+” side upward. (Fig. 2)

4) Replace the battery cover by reversing the
removal procedure.

PAPER ROLL REPLACEMENT

Never insert paper roll if torn. Doing so will cause
paper to jam. Always cut leading edge with
scissors first.

1) Insert the leading edge of the paper roll into the
opening. (Fig. 1)

2) Turn the power on and feed the paper by pressing

. (Fig. 2)

3) Lift the attached metal paper holder up and insert
the paper roll to the paper holder. (Fig. 3)

INK ROLLER REPLACEMENT

If printing is blurry even when the ink roller is in the
proper position, replace the roller.

Ink roller: Type EA-781R-BK (Black)

Type EA-781R-RD (Red)

WARNING

APPLYING INK TO WORN INK ROLLER OR
USE OF UNAPPROVED INK ROLLER MAY
CAUSE SERIOUS DAMAGE TO PRINTER.

1) Set the power switch to OFF.

2) Remove the printer cover. (Fig. 1)

3) Remove the ink roller by turning it counterclockwise
and pulling it upward. (Fig. 2)

4) Install the correct color new ink roller and press it

Cleaning the printing mechanism

If the print becomes dull after long time usage,
clean the printing wheel according to the
following procedures:

1) Remove the printer cover and the ink roller.

2) Install the paper roll and feed it until it comes out
of the front of the printing mechanism.

3) Put a small brush (like a tooth brush) lightly to the
printing wheel and clean it by pressing .

ERRORS

There are several situations which will cause an
overflow or an error condition. When this occurs, “←”
will be displayed. The contents of the memory at the
time of the error are retained.
If “← ” is displayed at the time of the error,
“•••••••••••••••••” will be printed in black and must
be used to clear the calculator.

Error conditions:

1. When the integer portion of an answer exceeds
12 digits.

2. When the integer portion of the contents of the
memory exceeds 12 digits.
(Ex. 999999999999 1 )

3. When any number is divided by zero. (Ex. 5 0

).

you exceed the buffer limit by pressing keys
sequentiallly during printing.

REPLACEMENT OF BATTERY FOR MEMORY PROTECTION

Time for battery replacement
