The Canon MC-G307 Maintenance Cartridge (6799C001) is the genuine Canon replacement waste-ink collector for select PIXMA MegaTank printers, specifically the PIXMA G4280 and G3290. Over time, everyday cleaning cycles and borderless printing produce residual ink. This easy-to-replace cartridge safely stores that waste ink, preventing leaks, safeguarding internal components, and helping your Canon printhead deliver consistent, spot-free output.
Made to Canon’s exacting standards, the MC-G307 is the precise match for the PIXMA G4280 and G3290. Using Canon OEM maintenance parts ensures proper sensor readings, accurate ink absorption, and seamless status monitoring—critical for avoiding unexpected shutdowns when a cartridge becomes saturated.
Inkjet printers run periodic purge and cleaning cycles to keep nozzles clear. The MC-G307 captures this waste ink. Replacing a saturated maintenance cartridge prevents overflow and protects delicate internal assemblies. The result is clean, dependable printing with fewer messes, fewer interruptions, and longer printer life.
Canon designed the MC-G307 for quick, do-it-yourself servicing. When your PIXMA displays a maintenance cartridge warning, simply open the access panel, release the old cartridge, and click the new one into place. No tools, no guesswork, and no risk of ink spills when handled as directed.
Whether you’re printing school projects, family photos, or everyday documents, a properly maintained ink system ensures smooth gradients, sharp text, and reliable color. The MC-G307 helps your PIXMA G4280/G3290 maintain optimal performance from the first page to the last.
Third-party maintenance cartridges can vary in fit and absorption performance, potentially causing improper sensor readings or leaks. Canon’s MC-G307 is engineered for the exact geometry, foam density, and absorption rate your PIXMA uses—backed by Canon’s quality control for peace of mind.
Wait for your printer’s prompt before replacing the cartridge to maximize its life. Keep the new MC-G307 sealed until installation. Remove the old unit carefully and keep the absorbent pad upright to avoid drips. Dispose or recycle according to local regulations for ink-containing components.
Pair your MC-G307 with genuine Canon inks and Canon photo or plain papers for best results. A small anti-static mat or disposable gloves can make the swap cleaner, especially in high-volume environments where maintenance is routine.
Canon’s MegaTank printers are built for low running costs and long-haul reliability. The MC-G307 complements that mission by making periodic maintenance quick and predictable—so you spend more time printing and less time troubleshooting.
