Where can I find the cartridge number of my cartridge?

The number of your cartridge is on the label of the cartridge. If it is not on the label, you can find it on the side of the cartridge at some instances. Examples of cartridge numbers are “CL-541” or “305”. This applies for both original and remanufactured cartridges. If there is no cartridge number at all, you can enter it in the calculator to the best of your knowledge, we will ensure the correct value for payment during sorting.
