Canon MAXIFY GX5560 MegaTank Ink Bottles
Your Canon MAXIFY GX5560 MegaTank uses the GI-66 ink bottles. Supplying these high-yield reservoirs since Jan 2025, we understand this continuous ink system serves busy workplaces where heavy document production is normal. Because black text needs dominate workplace workflows, tracking individual colour depletion rates prevents unexpected printing interruptions. Our 4.8 Google Star rating shows that our customers consistently receive high-quality cartridges backed by reliable performance.
Expected page output and replacement cycles
Canon determines the page yield metrics for these GI-66 desktop inkjet ink bottles using the international ISO/IEC 24711 standard, simulating continuous office printing. Workplace document environments heavily utilising monochrome output will naturally drain the black reservoir faster, though purchasing full multi-bottle multipacks ahead of time ensures colour workflows remain balanced during large business print runs.

Pro Tip
Always wait until the physical ink level drops below the lower line indicator on the printer tank before topping up with a new GI-66 bottle, as overfilling can cause internal reservoir spills or sensor reading errors.
Frequently Asked Questions
Can I mix partially used GI-66 ink bottles or store them long term after opening?
Once a GI-66 bottle is opened, the airtight seal is compromised. You should recap the bottle tightly and store it vertically in a cool, dark place, using the remaining ink within six months to prevent viscosity changes from altering printhead performance.
Why does the MAXIFY GX5560 show low ink warnings if the tank looks partially full?
The printer estimates ink levels electronically alongside the physical tanks. If you refill a tank without manually resetting the ink level counter through the printer maintenance menu, the system will continue to flag inaccurate low-ink warnings.
Do the colour GI-66 bottles deplete evenly during standard office operations?
No, because office documents use distinct colour distributions. Even if you print mostly greyscale text, small amounts of cyan, magenta, and yellow ink are spent during printhead cleaning cycles, meaning colour levels will slowly reduce at different rates over time.
