Pro Tip
Always wait until the ink level in your EcoTank reservoir reaches the lower fill line before opening a new T664 bottle, and pour the entire bottle in a single session to prevent ink oxidation inside partially used bottles.
Frequently Asked Questions
Do the Epson EcoTank ET-2500 and ET-2550 share the exact same ink bottles?
Yes. Both the ET-2500 and ET-2550 printer models belong to the same EcoTank series and use identical Epson T664 ink bottles across black, cyan, magenta, and yellow reservoirs.
Can I top up EcoTank reservoirs before they are completely empty?
Yes, you can top up the ink tanks at any point before they fall below the minimum fill line. Refilling early avoids running the printhead dry, which can cause air bubbles in the ink delivery lines.
How long can unopened T664 ink bottles be stored?
Unopened T664 ink bottles typically have a shelf life of up to two years when stored upright in a cool, dry location away from direct sunlight.
Why does colour ink deplete when printing monochrome text documents?
The printer uses small amounts of colour ink during periodic automatic maintenance routines to keep all printhead nozzles clear and prevent clogging, even if you select black-and-white print modes.
