Sharp QS2760H Ribbon Printing Calculator

THE KEYBOARD

OPERATING CONTROLS

• POWER SWITCH: When the power switch is turned on, the calculator is ready for operation.
• PRINT MODE SELECTOR: “P” position: The calculator functions as a print/display calculator. (Print mode)
  • “Position: The calculator functions as a display calculator. (Non-print mode)
  Mode change print: When changing the print mode selector, the following print will appear. “• • • …. • • • –P” (red print): When changing the selector from P to •. “• • • …. • • • +P” (red print): When changing the selector from • to P.
• GRAND TOTAL / RATE SETTING MODE SELECTOR:
  “GT” position: This selector will accumulate the following: (The symbol “ +” will be printed.)
• Addition and subtraction totals are obtained with the or key.
• Product and quotient totals obtained with the or key.
• Answers obtained with the or key. “•” position: Neutral, GT OFF position:
  • Enter the adding tax rate, then press.
  • To store a discount rate, press before pressing
• ADD MODE SELECTOR: “A/+” position – Effective only in addition and subtraction: Use of the A/+ mode permits addition and subtraction of numbers without an entry of the decimal point. When the A/+ mode is activated, the decimal point is automatically positioned according to the decimal selector setting.
  EXAMPLES: Set A/+- • -A/x to A/+ A. Set decimal to 2. Enter 12345.6 T.ape prints 1,234.56 + B. Set decimal to 3. Enter 12345.6. Tape prints 123.456 +
• ITEM COUNT MODE SELECTOR:
  “IC±” position: 1) The counter will count the number of times that the key has been pressed in addition.
• FIRST FACTOR ACCUMULATION SELECTOR: (Only QS-2770H)
  “FΣ” position: The first factor is automatically added to or subtracted from
  the memory. A first factor means the first number in multiplication and division, and each number is printed with “×I”
  and “÷I” respectively.
• CONSTANT MODE SELECTOR: “K” position: The following constant functions will be performed: Multiplication: The calculator will automatically remember the first number entered (the multiplicand) and the instruction. Division: The calculator will automatically remember the second number entered (the divisor) and the instruction.
• ROUNDING SELECTOR:
• DECIMAL SELECTOR:
  Sets the number of decimal places in the answer.
  In the “F” position, the answer is displayed in the floating decimal system.
• PAPER FEED KEY: When pressed, the paper feed key. Note: You can also pull the paper manually.
• RIGHT SHIFT KEY: Operation of this key in entered numbers or calculated results shifts the number one digit to the right, together with the decimal point. Used for one-digit correction.
• GRAND TOTAL KEY: Prints and clears the “GT” memory contents.
• NON-ADD/SUBTOTAL KEY: Prints the total of addition and subtraction with the symbol “ ”. This key also serves as a clear key for the calculation register and resets an error condition
• CLEAR ENTRY KEY: Clears the number entered before use of a function key. Also used to clear an overflow error caused by an entry
• NUMERAL KEYS
•  MINUS EQUALS KEY: Prints the entered number with a “–” symbol and subtracts the number from the contents of the calculation register. This key is also used to obtain the product/quotient in negative multiplication and division, and prints it with the symbol “
• PLUS EQUALS KEY: Prints the entered number with a “+” symbol and adds the number to the contents of the calculation register. This key is also used to obtain the results in multiplication and division, and prints the product/quotient with the symbol
• PERCENT KEY
• DIVISION KEY
• MULTIPLICATION KEY
• FIRST MEMORY PLUS KEY
• FIRST MEMORY MINUS KEY
• FIRST RECALL MEMORY KEY
• FIRST RECALL AND CLEAR MEMORY KEY
• SECOND RECALL AND CLEAR MEMORY KEY
• SECOND RECALL MEMORY KEY
• SECOND MEMORY MINUS KEY
• SECOND MEMORY PLUS KEY
• DATE KEY: (only QS-2770H) Can be used to store and display/print or recall the date or any other factor for repeated use in an application.
• AVERAGE KEY: Used to calculate the average.
• CHANGE SIGN KEY: Changes the algebraic sign of a number (i.e., positive to negative or negative to positive).
• MULTIPLE USE KEY: Used to perform mark-ups, percent change, and automatic add-on/discount.
• SQUARE ROOT KEY: To obtain the square root of a negative number, this calculator will first obtain the square root of the absolute value of the given number; the calculation result will then be converted to a negative value.
• TAX-INCLUDING KEY
• PRE-TAX KEY
• DISPLAY
  Display format:

Symbols:

First memory symbol: Appears when a number has been stored in the First memory.
Second memory symbol: Appears when a number has been stored in the Second memory.
Minus symbol: Appears when a number is negative.
E: Error symbol: Appears when an overflow or other error is detected.
•: Total memory symbol: Appears when a number is in the 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. Set the power switch to the OFF position.
   Make sure that the print wheel has stopped.
   3. Remove the printer cover by sliding it towards the back of the calculator. (Fig. 1)
   4. Remove the used ribbon.
   5. Install 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. Make sure that the reel is securely in place.
   7. Thread the ribbon around the outside of the metal guides. (Fig. 2)
   8. Insert the right reel securely.
   9. Take up any slack by manually turning one of the reels.
   10. Replace the printer cover.
   11. Replace the paper roll.

PAPER ROLL REPLACEMENT

1. Lift the paper holder. (Fig. 1)
2. Fold the leading edge of the paper roll 3 to 5 cm. (Do not fold it slantwise.) (Fig. 2)
3. Insert the paper roll from the left side of the paper holder and make sure the paper
   roll is set in the proper direction (with the paper feeding from the bottom). (Fig. 3)
4. Insert the leading edge of the paper into the opening directly behind the print
   mechanism. (Fig. 4)
5. Press the paper feed key and feed the paper under the edge of the paper cutter.

ERRORS

Several situations 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 “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 or key, and the calculation can still be continued.

Error conditions:

1. Entry of more than 10 digits or 9 decimals. (QS-1760H) Entry of more than 12 digits or 11 decimals. (QS-2760H/2770H) This error can be cleared with the OR key.
2. When the integer portion of an answer exceeds 10 digits. (QS-1760H) When the integer portion of an answer exceeds 12 digits. (QS-2760H/2770H)
3. When the integer portion of the contents of the memory exceeds 10 digits. (QS-1760H) (Ex. 9999999999 1 ) When the integer portion of the contents of the memory exceeds 12 digits. (QS-2760H/2770H) (Ex. 999999999999 1 )
4. When any number is divided by zero. (Ex. 5 0 )

DECIMAL SYSTEM

Input override decimal feature
The calculator operates on a principle of floating decimal entries with a preset decimal
answers.

1. An entry may contain up to 9 decimal places, regardless of the decimal selector
   setting. (QS-1760H) An entry may contain up to 11 decimal places, regardless of the decimal selector setting. (QS-2760H/2770H)
2. Answers will be printed to the preset decimal position, except when an underflow
   condition prevails
