Pro Tip
Canon GI-66 ink bottles feature unique physical nozzles that only match the corresponding colour tank opening on your MegaTank printer, making it physically impossible to accidentally cross-contaminate and ruin your printer lines with the wrong colour.
Frequently Asked Questions
Why do compatible GI-66 colour bottles show a 14,000-page yield compared to the 6,000 pages of genuine bottles?
Compatible GI-66 cyan, magenta, and yellow bottles contain a higher physical volume of ink inside the bottle than standard genuine versions. Since the internal ink tanks of the MAXIFY GX series can hold this extra volume, you can empty the entire bottle into the reservoir to print more than double the pages before requiring a new bottle.
Can I mix a compatible GI-66BK black ink bottle with genuine GI-66 colour bottles?
Yes, each ink tank operates completely independently inside the MegaTank system. Mixing a compatible black ink bottle with genuine colour ink will not cause chemical reactions or clogging because the formulations are designed to coexist across the printhead nozzles.
Do these ink bottles dry out if my printer sits idle over holiday periods?
MegaTank pigment inks are less prone to fast evaporation inside the bottles, but idle printers risk ink settling or printhead nozzle crusting. It is critical to keep your printer plugged in so it can run its automated background maintenance cycles to keep the ink fluid.
