COMPUMATIC 2 x COMPUMATIC Compatible/Replacement Calculator Ink Roller Black/Red IR-40T for Canon P23-DH V, P27-DH and More

Works great! Happy to had found it here because I couldn’t find it at staples.

Couldn't be happier that the calculator ink cartridge was exactly as described. It was easy to install and came with an extra cartridge that fit perfectly in my Canon P23-DH II calculator. Also, the print is bright and very clear. Item arrived very quickly.

My calculator ink has been out for several months! I finally ordered these and they pop right in and my machine is like new. Wish I had bought these sooner.

Fit my calculator just fine. The red ink doesn't last very long.

I've had my Canon P23 - DH V, for a very long time, at least 10 years, I think. I really didn't want to purchase another because I know how this one works and it normally works great for me. Recently my print was very light, I clean it, I put in a new ink thing, (simply because I don know what it's called), and it still was very light, plus after I cleaned it, it was even worse, could barely see the numbers. I decided just to try a new ink, IR40T- black/red, I am so please with my decision. My colors are bright and the numbers are so clear, no more getting a microscope out to read them. I am going to guess that the ink I had, had somehow got old, even in it's package. I am tickled pink, lol, that this solved my ink problem. I would definitely recommend, if you have an older printing calculator, try just replacing the ink. I had no idea, just taking a chance that it would resolve my issue. I knew that if it didn't work, Amazon is a great company and would except a return and get my money back, then I would have just purchased a new one from Amazon, so they would have made a larger purchase. Also after I cleaned it, which I might have done the wrong way, at first it wouldn't work at the, till I just kept clicking the numbers and the +-, to get it to work. Thank You
