Choosing between genuine and compatible GI-66 ink
Compatible GI-66 ink bottles offer a lower cost per page for high-volume business environments without compromising nozzle flow or print clarity. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Read our genuine vs compatible guide for a complete comparison before choosing your supplies.
Ordering strategies for high-volume office printing
If you print text-heavy office documents, keep an extra black GI-66 bottle ready, as black ink depletes fastest in multi-page business runs. For businesses producing colour charts and marketing material, full multi-bottle bundles ensure you never run short mid-job. All compatible bottles include a money-back guarantee.

Commercial printing pro tip
MAXIFY GX MegaTank printers feature unique keyway bottle nozzles for each ink tank colour. When refilling, push the bottle nozzle straight down without squeezing the bottle body, allowing gravity to fill the internal tank and preventing air bubbles from entering the printhead feed lines.
Match Your Printing Habits to the Right Canon GI-66 Ink Bottle Pack
If all your colours are running low, the 4-Pack GI-66 Genuine (from $148.75) covers every colour in one order and qualifies for free delivery.
If only one colour has run dry, there's no need to replace the rest - a single Genuine GI-66BK cartridge (from $33.81) is the lowest-cost way to keep printing.
Watching the budget? Compatible cartridges match the fit and yield of genuine ink at a lower price, from $17.52 for a single GI-66BK cartridge or 5-pack GI-66 for $91.39.
For a high-volume office, buying in bulk cuts the cost per unit further - the 10-Pack GI-66 Compatible (from $180.85) works out cheapest per cartridge, while the 8-Pack GI-66 Genuine (from $294.47) is the equivalent option if you'd rather stick with official ink. Both qualify for free delivery.
Frequently Asked Questions
Can pigment inks in GI-66 bottles clog printheads if left unused?
GI-66 inks use pigment formulas for water-resistant prints. If your MAXIFY printer sits idle for several weeks, perform a standard printhead nozzle check from the maintenance menu rather than running deep cleaning cycles, which consume unnecessary ink.
Can I top up a partially empty tank with compatible GI-66 ink if genuine ink is still inside?
Yes, compatible GI-66 ink can be added directly into tanks containing residual genuine Canon ink. Both formulations use compatible dye and pigment bases, so topping up will not cause settling or clogging within the printhead system.
Why do compatible GI-66 colour bottles list higher page yields than genuine bottles?
Compatible manufacturers fill GI-66 colour bottles to full fluid capacity, whereas genuine standard colour bottles contain less fluid. This higher fluid volume allows compatible colour bottles to deliver up to 14,000 pages per fill under standard test conditions.
Is GI-66BK the same as GI66BK?
Yes, GI-66BK and GI66BK refer to the same Canon black ink bottle code. The hyphen is standard formatting used on official packaging, but both codes describe the exact same bottle.
