Compatible Epson 664 EcoTank Ink

Looking for ink for your Epson EcoTank? The bottle you need is the Epson 664 (T664). Our compatible version yields 4,000 pages with the same print quality and costs a fraction of the original. See the compatible ink bottle.

Epson's EcoTank systems (also called ITS, refillable ink tank system) don't use cartridges: you refill them by pouring the ink straight from a bottle into the printer's tank. That's why the correct consumable is an ink bottle, not a cartridge or a toner. The entire family that starts with the EcoTank L100 shares exactly the same bottle reference: the Epson 664.

Is it compatible with your printer?

The Epson 664 is the bottle fitted by all of these EcoTank models, both the L series (the original European naming) and the ET series (the equivalent commercial name used in other campaigns). You'll notice small differences in the naming depending on whether the device is a printer only or an all-in-one with scan and copy, and on whether it includes a network or Wi-Fi connection, but the ink they need is the same. If you have any of these models, this is your bottle:

The consumable you need and what it yields

The correct consumable for this entire family is the compatible Epson 664 ink bottle. Each bottle yields 4,000 pages, a yield measured under the ISO/IEC 24711 standard, which is the international standard for measuring the life of inkjet bottles and cartridges. That's the same criterion used to measure the original ink, so the yield comparison is a fair one.

Because it's a refillable tank system, you're not dependent on cartridges: you refill the tank with the bottle and keep printing until it runs out. This drastically reduces the number of replacements compared with a traditional cartridge printer, and that's why the cost per page of an EcoTank is so low. If you want to dig deeper into how ink bottles and cartridges work, we have our complete guide to ink cartridges.

How much printing costs you

The key point is simple: our compatible Epson 664 bottle delivers the same 4,000-page yield as the original, but for far less money. You're not paying for the brand, you're paying for the ink. On a high-yield consumable like this, the price difference multiplies page after page and really adds up by the end of the year.

Frequently asked questions

Will the compatible Epson 664 bottle work with my EcoTank?

Yes, as long as your model is one of the 21 EcoTank devices listed above (L and ET series that use the Epson 664 reference). They all share the same bottle. If your printer is on the list, this is the ink you need. If in doubt, check it in the printer finder.

How many pages does each bottle print?

Each bottle yields 4,000 pages under the ISO/IEC 24711 standard. It's the same standard Epson uses to measure its original ink, so the yield is directly comparable.

Does using compatible ink void my printer's warranty?

No. Using compatible consumables does not void your printer's legal warranty. Article 120 of Royal Legislative Decree 1/2007 (the General Law for the Protection of Consumers and Users) protects you: the manufacturer cannot force you to buy only its brand to keep the warranty. On top of that, our ink comes with its own 3-year warranty.

How long does shipping take?

We ship within 24-48 hours to mainland Spain, and shipping is free on orders over €50. That way you have your ink ready before you run out.
