Frequently Asked Questions - EL-2901RH SHARP

How to replace the paper roll?

Carefully cut the beginning of the roll if it is torn. Insert the end into the opening, turn on the calculator and press ↑ to feed the paper. Lift the metal support and insert the roll.

How to replace the ink roller?

Turn the switch to OFF, remove the printer cover. Grasp the ink roller from the top, pull it towards you and upwards. Install the new roller (type EA-772R) in place, then replace the cover.

What to do if the print is faint?

First check the position of the ink roller. If necessary, replace it with a new roller (type EA-772R). If the print is still faint, clean the print wheel with a small brush (toothbrush) while pressing ↑ after removing the roller.

What do the symbols on the display mean?

The symbols are: M (active memory), - (negative number), GT (grand total in memory), E (error or overflow). Not all are displayed simultaneously.

How to set the tax rate?

Set the grand total/rate setting selector to RATE SET. Enter the rate (up to 4 digits, decimal point does not count) then press TAX+. Only one rate can be stored.

How to calculate cost, sell, or margin?

Use the COST (cost price), SELL (selling price), and MGN (margin) keys. Enter the known value, then press the corresponding key to calculate the unknown. For example, for selling price with a cost of 350 and a margin of 30%: 350 COST 30 MGN then SELL.

What to do when 'E' (error) is displayed?

The error may be due to overflow (more than 12 digits) or division by zero. Press CE to clear. If '0·E' appears, press CE once. If the error persists after electromagnetic interference, press ON/CE and restart.

The calculator does not turn on, what to do?

Check that the power cord is properly plugged in and that the mains voltage is correct (220-230 V). If the calculator does not respond, unplug it for 5 seconds then plug back in. If the problem persists, contact an authorized SHARP service center.

How to use the print and item count mode?

Set the selector to P•IC. During additions, each press of + adds one to the item counter; subtractions (-) subtract one. The count is printed with the result. The counter resets by pressing * or CE. Maximum capacity: ±999.

What are the usage precautions?

Do not expose the calculator to moisture, dust, or large temperature variations. Clean with a soft, dry cloth. Do not use solvents. Do not wrap the cord around the calculator. In case of malfunction, unplug and contact an authorized service center.

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 * , % CE % CE 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 = 0.444..., 5 ÷ 9 = 0.555...

	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 tax rate, then press TAX+ .
• A maximum of 4 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:

"6 3 2 1 0": 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. 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 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)

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

If an “0·E” is displayed at the time of the error, “— — — — — — ” will be printed in red and %_CE must be used to clear the calculator.

Also, in rare cases, printing may stop midway and the indication “E” 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 C/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. *M 9999999999999 M+ 1 M+)

1. When any number is divided by zero.

(Ex. 5 ÷ 0 = )
