Sharp EL-2630P - Electronic Printing Calculator Manual

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 you pull out the power cord to cut electricity completely, the presently stored tax rate will be cleared.

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.

''P•IC'' is on:
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 , or clears the counter.

''P•IC'' is off: Neutral

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.

DECIMAL SELECTOR

Presets the number of decimal places in the answer. In the ''F'' position, the answer is displayed in the floating decimal system.

CONSTANT/ADD MODE SELECTOR

''K'': The following constant functions will be performed:

Multiplication

The calculator will automatically remember the first number entered (the multiplicand) and instruction.

Division

The calculator will automatically remember the second number entered (the divisor) and instruction.

''•'': Neutral

''A'': Use of the Add mode permits addition and subtraction of numbers without an entry of the decimal point. When the Add mode is activated, the decimal point is automatically positioned according to the decimal selector setting.

Use of . and will automatically override the Add mode and decimally correct answers will be printed at the preset decimal position.

ROUNDING SELECTOR

"": An answer is rounded up.

"5/4": An answer is rounded off.

"": An answer is rounded down.

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

• A maximum of 4 digits can be stored (decimal point is not counted as a digit).

DISPLAY SYMBOLS

M: A number has been stored in memory.

–: The display value is negative.

E: Error or overflow of capacity.

• : Appears when a number is in the grand total memory.

INK RIBBON REPLACEMENT

1. Remove the paper roll from the calculator.(Tear the paper and remove it from the print mechanism by using .)
2. Turn the power off before replacing ribbon.
3. Remove the printer cover by sliding it towards the back of the calculator. (Fig. 1)
   
4. Remove the old ribbon by pulling it up.
5. Insert the new ribbon.
6. With the black side of the ribbon facing upwards, place one of the reels on the reel shaft on the right. (Fig. 2) Make sure that the reel is securely in place.
   
7. Thread the ribbon around the outside of the metal guides. (Fig. 3)
   
8. Take up any slack by manually turning one of the reels.
9. Replace the printer cover.
10. Replace the paper roll.

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. 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 ''0E'' is displayed at the time of the error, must be used to clear the calculator. If an ''E'' with any numerals except zero is displayed, the error may be cleared with or and the calculation can still be continued.

Error conditions:

1. Entry of more than 12 digits or 11 decimals. This error can be cleared with or .
2. When the integer portion of an answer exceeds 12 digits.
3. When the integer portion of the contents of the memory exceeds 12 digits.
   (Ex. 999999999999 1 )
4. When any number is divided by zero.
   (Ex. 5 0 )

Markup and Margin

Markup and Profit Margin are both ways of calculating percent profit.

• Profit margin is percent profit vs. selling price.
• Markup is percent profit vs. cost.
• Cost is the cost.
• Sell is the selling price.
• GP is the gross profit.
• Mkup is the percent profit based on cost.
• Mrgn is the percent profit based on selling price.

Percent change

• Calculate the dollar difference (a) and the percent change (b) between two yearly sales figures $1,500 in one year and $1,300 in the previous year.

TAX RATE CALCULATIONS

EXAMPLE 1: Set a 5% tax rate.
Calculate the tax on $800 and calculate the total including tax.

EXAMPLE 2: Perform two calculations using $840 and $525, both of which already include tax. Calculate the tax on the total and the total without tax.
