[LeJoy]

To replace the paper roll in your Canon P170-DH-3 Desktop Printing Calculator, follow these easy steps: First, ensure the calculator is switched off. Next, locate the paper compartment cover on the back of the calculator and open it. Remove the empty paper roll from the compartment by gently pulling it out. Take a new paper roll and insert it into the compartment, making sure the paper feeds from the bottom of the roll. Pull out a small amount of paper and close the paper compartment cover. Finally, turn the calculator back on and press the [PRINT] button to test the paper feed. For detailed visual instructions, please consult the "Paper Roll Replacement" section in the Canon P170-DH-3 Desktop Printing Calculator Instruction Manual.
