I assume that you are talking about a Canon Canola P1016D calculator.
It uses an ink roller. Very slowly -- they last a long time.
I need to replace the roller in mine, so I've been googling like crazy. The solutions I've found have been in Europe -- expensive especially when you include shipping.
1) Pelikan 335685. They are a well-thought of German pen and ink manufacturer
link. There is also a 2 pack but given how long they last, a 1 pack seems better. I don't know how to order them in Canada.
2) BCW. They have two listings for this calculator but one is wrong.
Here is the right one. It's a 3 pack.
