Frequently Asked Questions - CS-2850A SHARP

How do I replace the ink roller on my Sharp CS-2850A?

First, turn off the calculator and unplug the AC adapter. Open the paper cover and remove the paper roll. Lift the ribbon cassette (ink roller holder) located over the print head. Snap out the old ink roller and snap in a new Sharp IR-20 (or equivalent) ink roller. Reinsert the ribbon cassette, replace the paper, and close the cover.

What does the 'GT' key do?

The GT (Grand Total) key accumulates the results of individual calculations. Each time you press the = key, the result is automatically added to the grand total memory. Pressing GT displays the accumulated total. To clear the grand total, press GT twice or use the CA (Clear All) key.

How do I set the tax rate for tax calculation?

1. Press and hold the TAX+ key until the display shows 'TAX%'. 2. Enter the tax rate (e.g., 8.25 for 8.25%). 3. Press the TAX+ key again to confirm. The rate is stored. To calculate tax, enter an amount and press TAX+ for adding tax or TAX- for subtracting tax.

Why does my calculator print red numbers?

The Sharp CS-2850A prints in black for positive results and in red for negative results. This is normal and helps you quickly identify negative amounts. If printing is always red, the ink roller may be upside-down (red side active) or the print head may need cleaning. Check proper installation of the ink roller.

How do I perform cost/sell/margin calculations?

Use the COST, SELL, and MARGIN keys. For example, to compute selling price given cost and margin: Enter the cost, press COST, enter the margin percentage, press MARGIN, then press SELL to get the selling price. Similarly, you can find cost or margin by pressing the respective keys after entering the other two values.

Can I use the calculator without printing?

Yes, you can. The printer can be turned off by setting the PRINTER ON/OFF switch to OFF. The calculator will still function and display results on the LCD. To resume printing, set the switch back to ON. Note that the 'non-print' mode does not affect memory operations.

What type of paper does the CS-2850A use?

The calculator uses standard 58mm (2.25-inch) wide thermal or plain paper rolls, typically with a diameter of up to 60mm (2.4 inches) and a length of about 60 meters. Avoid using paper that is too thin or too thick—standard adding machine paper works best.

How do I clear the memory?

To clear the independent memory, press MRC (Memory Recall/Clear) twice quickly. The first press recalls the memory value; the second press clears it. To clear the grand total (GT) memory, press GT twice. For a full reset, press CA (Clear All), which clears the display, pending operations, and all memories.

What does the '5/4' rounding selector do?

The 5/4 switch determines decimal rounding. Set to 5/4 for round-off (5 rounds up, 4 rounds down), F for floating decimal (no rounding), CUT (or down arrow) to always round down (truncation), and UP (or up arrow) to always round up. Used with the decimal selector to control the number of displayed decimal places.

Why is the printer not printing or printing faintly?

First, ensure the printer switch is ON and paper is correctly installed. If printing is faint, the ink roller may be dry or worn—replace it with a new Sharp IR-20 ink roller. Also, check that the ink roller is fully seated and rotating when the printer operates. If the problem persists, clean the print head with a soft, dry cloth.

ERRORS

There are several situations which will cause an overflow or an error condition. When this occurs, the error symbol “E” will be displayed and all keys will electronically lock. The contents of the memory at the time of the error are retained.

If an “0·E” is printed on the tape at the time of the error, the * key must be used to clear the calculator. If an “E” with any numerals except zero is printed on the tape or if an “E” is not printed on the tape, the error may be cleared with the cor key 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 the CE or +key.

1. When the integer portion of an answer exceeds 12 digits.
2. When the integer portion of the contents of the memory or grand total memory exceeds 12 digits.

(Ex. *I 9999999999999 +I1 )+I

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

DECIMAL SYSTEM

ADD-ON/DISCOUNT RECARGOS/DESCUENTOS

EXAMPLE: 1 A 5% add-on to 100.

EJEMPLO: 1 Un 5% de recargo sobre 100.

EXAMPLE: 2 A 10% discount on 100.

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

The difference is:

– Profit margin is percent profit vs. selling price.
– Markup is percent profit vs. cost.

Note: In some cases, negative percentages will be shown for margin or markup. This is a normal function of the calculation logic.

EXAMPLE: Calculate the profit margin of a \65.00 item being sold at \89.00.

EXAMPLE: Calculate the selling price (a) and the gross profit (b) from a cost of \$8,160 on the basis of a 15% profit on the selling price.

COST (USING MARGIN) / COSTE (UTILIZANDO MARGEN)

EXAMPLE: Calculate the cost (a) and the gross profit (b) from a selling price of \$500 on the basis of a 35% profit on the selling price.

EXAMPLE: Calculate the markup of a \150.00 item being sold at \200.00.

EXAMPLE: Calculate the selling price (a) and gross profit (b) from a cost of \$6,950 on the basis of a 25% profit on the cost.

EXAMPLE: Calculate the cost (a) and the gross profit (b) from a selling price of \$9,780 on the basis of a 20% profit on the cost.

EXAMPLE: 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.

EXAMPLE: Calculate the percentage of each of the parts is to the whole.

EXAMPLE: Set a 5% tax rate.

Calculate the tax on \$800 and calculate the total including tax.

1. Set the decimal selector as specified in each example.
   The rounding selector should be in the "5/4" position unless otherwise specified.
2. The grand total mode, constant mode, add mode, item count mode and rate setting mode selectors should be in the “●” position (off position) unless otherwise specified.
3. Print mode selector should be in the "P" position unless otherwise specified.

AVERAGING

Calculate the average of a series of values.

SOLUTION: 1. Add the values to calculate the TOTAL VALUES.

1. Determine the NUMBER OF VALUES.
2. Calculate the average.

FORMULA:

$$ \text { Average } = \frac {\text { Total of the values }}{\text { Number of values }} $$

EXAMPLE: Day Sales

COMPOUND INTEREST

Calculate the new balance on a deposit which is compounded quarterly for 4 years as a given annual interest rate.

SOLUTION: 1. Calculate the quarterly interest rate.

1. Calculate the new balance (principal plus interest)

FORMULA: New balance = P(1 + i)

Where P = amount of deposit (principal)

i = interest rate per period

n = number of years × 4

EXAMPLE: If P = \$6,150

$$ \mathrm{i} = 5 \% \text { annum } \quad \div 4 \text { periods } = 0. 0 1 2 5 $$

$$ n = 1 6 (4 \text { years } \times 4) $$

Then 6,150 (1.0125) ^16 = \$7,502.32 (New Balance)
