Calculator Ink Rollers: How to Find the Right One

What an ink roller does

A printing calculator prints its results on a small paper roll, using an ink roller — a small, inked roller that the print mechanism presses against the paper. When the print becomes pale, the ink roller is usually the part to replace, not the whole calculator. Check your calculator's manual for the exact roller reference: similar-looking rollers are not interchangeable.

References people often search for

Two references come up very often in searches for calculator ink rollers: the universal IR-40T (also listed as CP-13 or MP-12D) and the Casio IR-60. Please note honestly: neither of these two references is currently listed in this shop's catalogue. They are mentioned here so you can recognise the reference on your own calculator or on your old roller, and check a product page before ordering anything. Do not assume a roller fits your calculator just because it looks the same size.

Always check the compatibility list on the product page itself for your calculator model before ordering.

How to identify your roller

1. Find your calculator's brand and model (usually on a label underneath).

2. Look at the old roller: its reference is often printed on it, or given in the calculator's manual.

3. Search the shop by that reference, and compare it with the compatibility list on the product page.

4. If you cannot find the reference, contact the shop through the Contact page with your calculator's model — do not guess.

When to replace an ink roller

Replace it when print becomes pale, uneven or hard to read, even after checking that the paper roll is correctly loaded. Keeping one spare roller of the same reference avoids interruptions.
