Question not answered?Ask a question
Use our 'Check this ink fits your printer' box at the top of this page to confirm this cartridge is suitable for your printer model. In most cases the model number is written on the front of your printer.
Note: These cartridges will only work in printers purchased in the UK and Europe. Printers purchased outside of these zones will have different coding and electronics.
We don't advise on the number of millilitres, as not every cartridge prints using the same droplet size, so two cartridges for two different printers may both have 5ml of ink, but one will print more than the other. Instead, more accurately, the industry standard is based on printing 5% of an A4 page.
This is known as page yield. The number of pages you'll be able to print depends on the cartridge you purchase and the kind of printing you do. The page yields shown higher up the page are based on printing 5% of the area on an A4 page.
