The P26-DH II is a printing calculator produced by Canon. It is generally used for accounting and record keeping, though it can also serve the needs of the average arithmetic student. Although now out of production, the P26-DH II is popular on the secondhand electronics market. The calculator can be attached to any household electrical outlet and, thus, requires no batteries to operate. With a replacement paper roll and help from the steps that follow, you'll be printing off receipts for your records in no time.
Installing a Replacement Roll
Move the power switch in the upper right corner of the calculator to the "Off" position.
Push the wire roll holder back so it protrudes from the back of the calculator. Place the replacement roll on the holder so the paper's end extends from the bottom of the roll.
Cut the paper's end diagonally and insert it into the slot in the back of the calculator.
Move the power switch to the "PRT" position to turn on the calculator.
Press the paper feed button on the upper left of the calculator. The button is designated by an upward-pointing arrow.
Using the Calculator
Set the calculator's tax rate, if you'll be using it for accounting purposes. Move the power switch to the "RATE SET" position. Use the number pad to key in your state's or locality's correct tax rate. Move the power switch back to "PRT" when you have keyed in the rate.
Slide the "Decimal Point" switch at the top center of the calculator to "2." This ensures proper placement of the decimal point during calculation.
Move the "Round-Off" switch to "5/4" to ensure proper rounding of multiplication products. Numbers ending in "5" will be round up, while those ending in "4" are round down.
Enter numerical values using the number pad. Use the addition, subtraction, multiplication or division keys as needed. Delete incorrect inputs by pressing the right-facing arrow key.
Add sales tax to a value by pressing the "TAX+" key. Clear the screen by pressing the "CE/C" key.
