I Need Ink. Can Barely Read The Writing On Tape

I'm sorry to hear that you're having trouble with your Casio HR 100TM calculator's printing quality. The Casio HR 100TM calculator uses standard IR-40 ink roller cartridges, which are widely available at office supply stores, online retailers, and through Casio's website.

To replace the ink roller in your Casio HR 100TM calculator, follow these steps:

1. Turn off the calculator and unplug it from any power source.
2. Open the printer cover by lifting up on the tab on the back of the calculator.
3. Remove the old ink roller by pulling it straight up and out of the slot.
4. Insert the new ink roller into the slot, with the black roller facing the paper.
5. Press down firmly on the ink roller until it snaps into place.
6. Close the printer cover and turn on the calculator.

Your Casio HR 100TM calculator should now be ready to print clearly again. Please mark as helpful as it takes time to write all this.
