Compatible Canon MC-G07 Maintenance Cartridge for G3780 / G4780

Canon MC-G07 maintenance cartridge for G3780 and G4780

This Canon MC-G07 maintenance cartridge is a third-party compatible replacement listed for the Canon PIXMA G3780 and G4780. It collects waste ink from cleaning and maintenance rather than supplying ink to print documents. This product is not an original Canon cartridge.

Check the number on the printer itself, especially if you are choosing between G3770 and G3780 supplies. Canon specifies MC-G07 for G3780 and G4780, but MC-G04 for G3770. A single changed digit in the printer name can mean a different maintenance box.

Match the reference before ordering

Use the full printer model and the label on the existing cartridge together. Canon’s specifications establish the required reference; they do not certify the supplied compatible unit. Do not add a printer to the fit list simply because a seller describes a cartridge as suitable for the wider G series.

What the replacement warning means

Canon’s G3080-series replacement guide distinguishes a nearly full cartridge from a full one. Replace a nearly full cartridge promptly. When it is full, printing is disabled until a new maintenance cartridge is installed. A low-ink message is different and needs its own remedy.

Follow your printer’s replacement instructions, including the power-off step in the cited G3080-series guide. Handle the old cartridge gently, keep it upright and avoid touching the terminal or opening. Used maintenance cartridges contain ink, so protect nearby surfaces and follow local disposal requirements.

Buyer questions

Which maintenance cartridge does Canon G3780 use?

Canon specifies MC-G07 for PIXMA G3780. This listing offers a compatible alternative with that reference; confirm the printer label before ordering.

Is MC-G07 also the reference for G4780?

Yes. Canon’s G4780 specifications name MC-G07 as its maintenance cartridge. G4780 is also included in this product’s existing catalog fit list.

Will it replace the MC-G04 in a G3770?

No. G3770 uses MC-G04, while G3780 uses MC-G07. Select the cartridge by its exact reference rather than the similar printer name or box shape.

Is the cartridge genuine Canon?

No. This is a third-party compatible replacement. The Canon name identifies the intended printer system, not the manufacturer of the item supplied under this listing.

Should I buy a reset chip instead?

A chip-only listing is a different item from a maintenance cartridge. Canon’s cited instructions call for a new cartridge when full; this page does not promise chip replacement, resetting or reuse of the old box.
