Compatible High Capacity Canon CLi-571 Magenta Ink Cartridge (STCLI-571XLM)

I'm sorry for any confusion caused.

To give you an idea of how many pages any ink cartridge can print, we use the 5% coverage method/rule. This method is used industry wide from manufacturers all the way to the consumers.

The way it works is, the ink cartridge in question is tested by the manufacturer to confirm the maximum amount of pages it can produce. This is done by them printing the exact same print over and over again, until the cartridge registers as out of ink. The print is always 5% coverage on A4 page, which looks like a few short sentences on the page in a standard text size.

Manufacturers use the page yield method as it's much clearer way for people to see what they are getting from a product, rather than using ml's. There's no intentional reason why the page yield differs between colours or clear connection between the amount of ml's and the page yield.

I hope this helps, if you have any further questions please contact us at sales@stinkyink.com.
