Canon MC-G307 F/Pixma G4280,G3290 Maintenance Cartridge

Keep your Canon PIXMA MegaTank printer performing at its best with the Canon MC-G307 Maintenance Cartridge (Part No. 6799C001). Engineered specifically to collect and contain waste ink generated during printhead cleaning cycles and borderless printing, this genuine Canon component helps maintain optimal print quality and prevents unexpected maintenance errors. Tailored for PIXMA G4280 and G3290 models, the MC-G307 is an essential consumable that supports long-term reliability and clean operation.

MegaTank printers periodically purge and clean the printhead to sustain crisp text and vibrant color output. The MC-G307 acts as the internal repository for that waste ink, ensuring it’s safely captured and isolated. By replacing the cartridge when prompted, you protect your device from overflow conditions and help avoid downtime, messy leaks, or service interruptions.

The Canon MC-G307 is designed for use with the following PIXMA MegaTank printers:
- PIXMA G4280
- PIXMA G3290

If your printer displays a maintenance cartridge warning or reaches the waste ink capacity threshold, the MC-G307 is the correct replacement part for the models listed above.

- Genuine Canon OEM quality: Perfect fit and reliable performance backed by Canon’s engineering standards.
- Clean, safe ink containment: Minimizes risk of interior staining or spills and helps keep your printer’s maintenance cycles smooth.
- Hassle-free installation: The cartridge slides into place; the printer detects and updates its maintenance status automatically.
- Sustained performance: Proper waste-ink management supports consistent output quality over the life of your printer.
- Smart replacement alerts: Your PIXMA proactively warns when capacity nears its limit, helping you replace the cartridge before workflow is impacted.

During cleaning and priming routines, a small amount of ink is directed away from the printhead to maintain nozzle health. The MC-G307 stores this waste ink within an absorbent core. Over time, the cartridge reaches its designed capacity. When that happens, the printer issues a maintenance notification, prompting you to replace the unit. Swapping the MC-G307 resets the waste-ink counter, restores normal operation, and preserves your printer’s internal cleanliness.

1) Power on your printer and follow any on-screen instructions related to maintenance cartridge replacement.
2) Open the maintenance access door as indicated in your printer’s user guide.
3) Carefully remove the saturated MC-G307; avoid tilting to prevent drips.
4) Unpack the new MC-G307 (6799C001) and slide it into the designated slot until it seats securely.
5) Close the access door; the printer will recognize the new cartridge and reset the maintenance counter.

Tip: Keep some paper towels nearby just in case, and dispose of the used cartridge according to local regulations for ink-containing consumables.

- Always use genuine Canon maintenance cartridges to ensure correct fit, capacity reporting, and system reliability.
- Replace promptly when alerted; running past capacity may trigger errors and interrupt printing.
- Pair regular maintenance with genuine Canon ink bottles appropriate for your model to maintain optimal color fidelity and page yields.
- Store spare cartridges sealed and upright in a cool, dry place until needed.

Canon’s maintenance cartridges are calibrated to the waste-ink monitoring logic inside your PIXMA MegaTank printer. OEM parts ensure accurate capacity tracking, proper sealing, and consistent absorbency, reducing the risk of alerts, leaks, or compatibility issues that can arise with non-original components.

Canon uses different maintenance cartridges across the MegaTank family, and each is tailored to specific chassis designs and waste-ink profiles. The MC-G307 is matched to the PIXMA G4280 and G3290 architecture. Installing the correct cartridge for your exact model ensures accurate capacity monitoring and secure, leak-free seating.

- "Maintenance Cartridge Full" or similar alert: Indicates the MC-G307 has reached capacity and must be replaced.
- Visible internal ink staining or recurring cleaning cycles: Check maintenance status; repeated cleaning increases waste-ink volume.
- Post-replacement prompts: After installing a new MC-G307, the printer will reset the internal counter automatically. If it doesn’t, power cycle the printer and confirm the door is fully closed.

The MC-G307 contains absorbed ink and should be disposed of responsibly. Follow local guidelines for ink-contaminated consumables. Many communities and office recycling programs provide guidance for printer maintenance parts. Using OEM cartridges helps reduce risk of leaks during handling and disposal.
