Epson EcoTank ET-2810 Ink Bottles
Your Epson EcoTank ET-2810 uses the T522 ink bottle system, featuring individual reservoirs for black, cyan, magenta, and yellow. We have been supplying reliable consumables for this printer since Oct 2021, helping home users maintain consistent print setups. Because this design relies on continuous liquid ink flow rather than integrated printheads, regular colour printing is essential to prevent microscopic printhead nozzles from drying out. Our 4.8 Google Star rating shows that our customers consistently receive high-quality cartridges backed by reliable performance.
Genuine vs compatible ink bottles
Choosing between original manufacturers and alternative options comes down to upfront preference. Both variants deliver reliable ink flow through the EcoTank plumbing. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty.
Managing maintenance components
Beyond standard fluid refills, continuous flow setups occasionally require a replacement maintenance box or internal absorption system to capture waste fluids during automatic cleanings. Experience Tip: If your printer indicates the waste tank is full, replacing the physical part must be accompanied by a control panel sequence reset to register the fresh printer.
Stocking your home print supplies
If you generate text-heavy school assignments or household admin, buying individual black bottles as needed prevents excessive standing inventory. For creative hobbies or family photos, choosing combined value bundles lowers the overall cost per pack and ensures colour printing is never halted by a single depleted reservoir. Compatible options offer excellent everyday value and carry a full money-back guarantee if they fail to perform. You can find complete returns information at our Returns policy page. Free delivery applies on all orders over $99 (conditions apply), with goods dispatched quickly from our national warehouse network in Perth, Brisbane, Sydney, Melbourne, and Adelaide.

Pro Tip
Always wait until the liquid level falls below the lower indicator line on the physical printer window before refilling, but never let a reservoir run completely empty, as pumping air through the internal lines can introduce stubborn air bubbles that cause permanent streaking.
Frequently Asked Questions
Can I mix a genuine black bottle with compatible colour bottles in the EcoTank ET-2810?
Yes, each tank is independent. The physical liquid reservoirs hold fluid separately, meaning a compatible cyan, magenta, or yellow bottle will function seamlessly alongside an original genuine black bottle without any chemical incompatibility or system errors.
Why does the colour ink level drop slightly even though I only print black and white text?
The printer performs periodic automated maintenance flushes to clear dried liquid from the microscopic printhead nozzles. Because the black and colour nozzles reside on the same printhead array, small amounts of all four colours are consumed during these cleaning cycles to maintain system health.
Do these T522 bottles spill when you invert them to fill the ink reservoirs?
No, modern T522 bottles feature an internal pressure-activated valve and custom keyways unique to each colour slot. The liquid will not flow out when inverted and only opens when firmly pressed onto the correct corresponding tank inlet, preventing accidental cross-contamination.
