What Does the Canon MC-G04 Maintenance Cartridge Do?
During normal inkjet printer operation, a small amount of ink is used for maintenance processes such as print head cleaning and other automatic servicing routines. This excess ink needs to be safely collected inside the printer.
The Canon MC-G04 Maintenance Cartridge contains absorbent material designed to collect this waste ink. Over time the cartridge reaches its capacity and the printer will indicate when replacement is required.

Replace When Your Printer Prompts You
The maintenance cartridge gradually fills as the printer performs cleaning and maintenance operations. When its remaining capacity becomes low, a compatible Canon printer may display a warning advising that the maintenance cartridge will soon need replacement.
Once the cartridge reaches its replacement limit, printing may be restricted until a new maintenance cartridge is installed. Keeping a spare MC-G04 available can therefore help minimise unnecessary printer downtime.
Genuine Canon Quality & Compatibility
The MC-G04 is manufactured by Canon for use with specifically supported Canon inkjet printers. Genuine Canon maintenance cartridges are designed to fit correctly within the printer and work with its internal maintenance monitoring system.
Using the correct maintenance cartridge is particularly important because similar-looking Canon maintenance cartridges are not necessarily interchangeable between printer models.
Simple User Replacement
The MC-G04 is designed as a replaceable consumable rather than a permanent internal waste ink component. When replacement is required, the existing maintenance cartridge can be removed and a new MC-G04 installed according to the instructions for your printer model.
Take care when removing a used maintenance cartridge, as it contains absorbed waste ink. Keep the cartridge level during removal and handling to help avoid ink leakage.

Why Does an Inkjet Printer Need a Maintenance Cartridge?
Inkjet printers periodically clean and service their print heads to maintain print quality and reduce the likelihood of blocked nozzles. These processes use small amounts of ink that are not transferred onto the printed page.
The maintenance cartridge provides a dedicated location for collecting this excess ink. This allows compatible printers to manage routine maintenance without allowing waste ink to accumulate freely inside the machine.

Frequently Asked Questions (FAQ)
What is the Canon MC-G04?
The Canon MC-G04 is a maintenance cartridge used by compatible Canon inkjet printers to collect excess ink produced during print head cleaning and other printer maintenance operations.
Is this a Genuine Canon maintenance cartridge?
Yes. This listing is for a Genuine Original Canon MC-G04 Maintenance Cartridge, not a compatible or third-party replacement.
Is the MC-G04 an ink cartridge?
No. The MC-G04 does not supply ink for printing. It is a waste ink maintenance cartridge that collects excess ink generated by the printer during maintenance operations.
When should I replace the MC-G04?
Replace the MC-G04 when your compatible Canon printer displays a warning or message indicating that the maintenance cartridge is approaching capacity or needs to be replaced.
Can I continue printing when the maintenance cartridge is full?
Once the maintenance cartridge reaches its replacement limit, the printer may restrict printing until a new cartridge is installed. Replacing it with the correct MC-G04 allows normal operation to resume.
Can I empty and reuse the Canon MC-G04?
The MC-G04 is designed as a replaceable consumable. Canon's intended maintenance procedure is to replace a full cartridge with a new one rather than emptying and reusing it.
Can I replace the MC-G04 myself?
Yes. On supported printers the MC-G04 is designed to be user replaceable. Follow the replacement procedure specified for your exact Canon printer model.
Does the maintenance cartridge need to be replaced at the same time as the ink?
No. The maintenance cartridge and printing ink have separate capacities. Replace the MC-G04 when the printer indicates that maintenance cartridge replacement is required.
Are all Canon maintenance cartridges interchangeable?
No. Canon produces different maintenance cartridges for different printer families. Always confirm that your exact printer model specifies MC-G04 before ordering.
Should I keep a spare MC-G04?
If the printer is important to your home or business workflow, keeping a spare can be useful because a printer may eventually stop normal printing once its installed maintenance cartridge reaches capacity.
