The Canon MC-G02 is a maintenance cartridge designed to collect waste ink that accumulates during the printing and cleaning cycles of your device. This component is essential for keeping your printer operational, as it serves as a reservoir for excess ink that would otherwise build up inside the machine. Built for convenience, this part is user-replaceable, meaning you can swap it out yourself without needing professional technical service. Once installed, the cartridge automatically resets the printer's waste ink counter, allowing you to continue printing immediately. It is compatible with several Canon PIXMA G-series MegaTank models, including the G1220, G1420, G2260, G2420, G2460, G3260, G3420, G3460, and G620.
