Canon has poured all the Know How of its extraordinary history of developing innovative office machines into each of its copiers, printers, and networked office systems. The same superiority of design and manufacture goes into all of the Canon-branded consumable imaging supplies and parts for this equipment. Naturally, no one makes better parts and supplies for Canon products than Canon. Using genuine Canon parts and supplies is your best insurance against equipment damage, and possibly voiding your equipment warranty.If you use your Canon Pixma printer for photo printing, you might have observed that the color cartridges seem to drain fast. The engineers at Canon are aware of this and have helped resolve the problem. Instead of requiring a complete ink cartridge replacement, the cartridge was designed as 2 modules: cartridge transfer mechanism and an ink tank.
