Each of these compatible CLI-571GYXL grey ink cartridges have been manufactured from scratch to offer a genuine alternative to the Canon original. Our manufacturers have worked tirelessly to produce a compatible CLI571GYXL that allows the ink to flow freely from the cartridge into the printer, but not infringe upon the Canon patents. This compatible Canon CLI-571 contains a high quality dye based grey ink that offers rich colours and a print quality comparable to the original ink. Whilst it may now offer the same UV protection it retain the same impressive 289 page yield at a bargain price. You can be assured of fully compatibility between this 0335C001 ink cartridge and the Canon Pixma MG7750 (along with all other printers listed on this page), but this cartridge still comes with our 100% satisfaction guarantee.
