Frequently Asked Questions - EL-2901RC SHARP

How to replace the ink roller on my SHARP EL-2901RC?

Set the switch to OFF. Remove the printer cover. Grasp the ink roller from the top, pull it toward you and upward. Install the new roller (type EA-772R) making sure it is seated properly. Replace the cover.

How to change the paper roll?

Carefully cut the beginning of the tape with scissors if the paper is torn. Insert the end of the roll into the opening. Turn on the calculator and press the paper advance key (↑) to feed the paper. Lift the metal holder and place the roll in the holder. Never pull the paper backwards.

What to do if the display shows 'E' and printing stops?

This may be due to overflow, division by zero, or electromagnetic interference. Press the CE/C key to clear the error. If the problem persists, unplug the calculator for 5 seconds then plug it back in.

How to set the euro conversion rate?

Set the grand total/rate mode selector to RATE SET. Enter the rate (e.g., 1.95583 for DEM) then press 100. The rate is stored. To use it, set the selector to GT or the neutral position.

How to use the cost/sell/margin calculation function?

Enter the cost and press COST, or the selling price and press SELL, or the margin and press MGN. The other two values are calculated automatically. To exit this mode, press CE/C.

Why is the printing faint?

The ink roller may be worn or mispositioned. Check that it is seated properly and replace if necessary. If printing remains faint, clean the print wheel with a small brush (like a toothbrush) while pressing the paper advance key.

What to do if the calculator becomes unresponsive after electrostatic shock?

Unplug the power cord from the AC outlet for about 5 seconds, then plug it back in and turn on the calculator. This should reset the system.

How to clear the memory and grand total?

To clear the memory, press the memory recall and clear key (R·CM). To clear the grand total, press GT followed by CE/C or use the appropriate sequence mentioned in the manual.

Can I use the calculator without plugging into mains?

No, the SHARP EL-2901RC operates only on AC power (220V-230V, 50 Hz). It does not have a backup battery.

How to clean the printer?

Remove the printer cover and the ink roller. Advance the paper until it comes out the front. Clean the print wheel with a small brush while pressing the paper advance key. Reinstall the roller and cover.

USER MANUAL EL-2901RC SHARP

The socket outlet shall be installed near the equipment and shall be easily accessible.

Caution!

To ensure 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 you pull out the power cord to cut electricity completely, the presently stored exchange rate will be cleared.
6. Do not wind the AC cord around the body or otherwise forcibly bend or twist it.

OPERATING CONTROLS

POWER SWITCH; PRINT / ITEM COUNT MODE SELECTOR:

"OFF": Power OFF

"": Power ON. Set to the non print mode.

"P": Power ON. Set to the print mode.

"P·IC": Power ON. Set to the print and item count mode.

For addition or subtraction, each time + is pressed, 1 is added to the item counter, and each time - is pressed, 1 is subtracted.

• The count is printed when the calculated result is obtained.
• Pressing of * , 9 / 2 clears the counter.

Note: The counter has a maximum capacity of 3 digits (up to ± 999 ). If the count exceeds the maximum, the counter will recount from zero.

ROUNDING SELECTOR:

Example: Set Decimal Selector to 2.

4 ÷ 9 = 0. 4 4 4 ... , 5 ÷ 9 = 0. 5 5 5 ...

	4÷9=	5÷9=
↑	0.45	0.56
5/4	0.44	0.56
↓	0.44	0.55

Note: The decimal point floats during successive calculation by the use of × or ÷ .

If the decimal selector is set to "F" then the answer is always rounded down (↓).

GRAND TOTAL / RATE SETTING MODE SELECTOR:

"GT": Grand Total

"": Neutral

"RATE SET": Rate setting

• Enter the adding exchange rate, then press
• A maximum of 6 digits can be stored (decimal point is not counted as a digit).
• Only one rate can be stored. If you enter a new rate, the previous rate will be cleared.

DECIMAL / ADD MODE SELECTOR:

"63210": Presets the number of decimal places in the answer.

"F": The answer is displayed in the floating decimal system.

"A": The decimal point in addition and subtraction entries is automatically positioned to the 2nd digit from the lowest digit of entry number. Use of the add mode permits addition and subtraction of numbers without entry of the decimal point. Use of · , × and ÷ will automatically override the add mode and decimally correct answers will be printed.

INK ROLLER REPLACEMENT

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

Ink roller: Type EA-772R

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) Hold the top of the ink roller and remove the roller by pulling it toward you and then upward. (Fig. 2) 4) Install the new ink roller in the correct position. Make sure that the roller is securely in place. (Fig. 3) 5) Put back the printer cover.

Fig. 1

Fig. 2

Fig. 3

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 4) Put back the ink roller and the printer cover.

Note: Do not rotate the printing mechanism manually, this may damage the printer.

PAPER ROLL REPLACEMENT

Never insert a paper roll if it is torn. Doing so will cause the paper to jam.

Always cut the 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 the [FEED] key. (Fig. 2) 3) Lift the attached metal paper holder up and insert the paper roll onto the paper holder. (Fig. 3)

Fig. 1

Fig. 2

Fig. 3

DO NOT PULL PAPER BACKWARDS AS THIS MAY CAUSE DAMAGE TO THE PRINTING MECHANISM.

ERRORS

There are several situations which will cause an overflow or an error condition. When this occurs, "E" will be displayed. The contents of the memory at the time of the error are retained.

Also, in rare cases, printing may stop midway and the indication "E" may appear on the display. This is not a malfunction but is caused when the calculator is exposed to strong electromagnetic noise or static electricity from an external source. Should this occur, press the [CE] key and then repeat the calculation from the beginning.

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. 9999999999999 + 1 +

1. When any number is divided by zero. (Ex. 5 0 = )
