Managing other printer components
The replacement process for this continuous ink system involves a separate MC-G02 maintenance kit, which houses the printer waste ink absorber. This user-replaceable part monitors excess ink collection from printhead cleanings.
Experience Tip: When replacing the MC-G02 maintenance kit, ensure the printer is turned on when installing the new module so the internal chip counter can reset correctly.
Buying options and delivery
If your daily print tasks lean heavily toward text documents, buying individual black ink bottles keeps upfront costs low. However, mixed text and colour printing setups benefit significantly from bundle packs to avoid uneven depletion. Genuine Canon ink bottles ordered from Ink Depot are backed by a complete manufacturer warranty. Free delivery applies on all orders over $99 (conditions apply). We dispatch daily from our local distribution centres across Australia in Perth, Brisbane, Sydney, Melbourne, and Adelaide to ensure prompt delivery.

Pro Tip
Always top up ink reservoirs before they fall below the lowest indicator line on the front of the printer; letting ink run completely dry pulls air into the supply lines, causing stubborn printhead blockages that consume vast amounts of ink to clear.
Frequently Asked Questions
Can I mix different ink series if the bottles fit into the neck of the tank?
No, you must only use genuine GI-61 bottles because the formulation is tuned precisely for the thermal nozzles of this model. Using incorrect ink types will compromise print clarity and can permanently clog the firing mechanisms.
How often does the MC-G02 maintenance kit actually need to be replaced compared to the ink?
The maintenance module collects waste ink from regular head priming and cleaning cycles. It typically lasts through multiple complete sets of refill bottles, but heavy printing or frequent manual deep cleanings will fill it faster.
Do these ink bottles have an expiry date once they are opened and poured?
While sealed bottles have a long shelf life, it is recommended to use the ink within six months of opening and filling the printer reservoirs to ensure optimal viscosity and prevent dust contamination inside the fluid lines.
