When recycling the empty Canon PG-545XL and CL-546XL ink cartridges our manufacturers have reused the genuine Canon printheads within each cartridge. This means our refilled Canon PG-545XL and CL-546XL ink cartridges retain much of the original print quality and that you can continue the successful running of the Canon Pixma iP2850 and all other compatible printers for the foreseeable future without purchasing brand new ink cartridges.Our remanufactured PG-545XL and CL-546XL are an eco-friendly alternative to the genuine high capacity Canon ink cartridges that contain between 13ml & 15ml of high quality dye based ink. The same high volume of ink as the original Canon PG-545XL and CL-546XL means you can expect the same estimated 300 and 400 page yield per cartridge and make yourself a handsome saving too.
