FAQs

Question not answered?

Ask a question

Will this cartridge work in my HP printer?

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.

How much ink is in a HP Original cartridge?

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.

How many pages will this HP Original cartridge print?

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.

Learn more about how many pages you'll be able to print with this cartridge in this article.

Will this cartridge work alongside HP Instant Ink cartridges?

No, you aren't able to use other cartridges alongside your HP Instant ink ones. Cartridges in the Instant Ink program have different coding, so whilst enrolled, you are locked into their service and must use their cartridges. Read our blog to learn more about HP Instant Ink.

Why are original cartridges so expensive?

There are a number of factors that affect the price of original (OEM) ink cartridges. This cartridge is made by HP themselves so they have ultimate control over the cost Stinkyink pay to stock them. Recent increases in the costs of raw materials and shipping for example have put more pressure prices. However, at Stinkyink we work constantly to keep prices low and offer a price-match guarantee on all original ink products.

Of course, in most cases you have the option save money with a Stinkyink compatible ink, which come with a 12-month money back guarantee. See the product comparison table further up this page for your options.
