Not an easy colour to get for my old canon printer. Very happy with quality Can980on Pixma MP980

Good product - unfortunately doesn't seem to last very long. Would be good to be able to get a compatible cartridge.

A member of the Stinkyink.com team has responded to this review. View more information.

Unfortunately only a small number of Canon models use the grey cartridge, compared to the other colours in that range. I'm afraid that this means that the manufacturers that we work with haven't seen the demand for a compatible, and so one isn't currently available.

The Canon original inks tend to last a slightly shorter length of time than the compatible equivalents as they have marginally less ink in them. Changing your printing to draft mode, where appropriate, should help it, and the other inks, to last a little longer.

Excellent product. I have a Canon Pixma MP980 and find it really easy to replace the cartriges. The print quality is first class and I would certainly recomment this product to other people.


Question not answered?

Ask a question

Will this cartridge work in my Canon 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 Canon PGi-520 and CLi-521 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 Canon PGi-520 and CLi-521 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.

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 Canon 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.
