What ink does the Epson EcoTank ET-7700 need, and 3 compatible models

Looking for ink for your Epson EcoTank ET-7700 or ET-7750? The bottle you need is the Epson 106. Our compatible version offers the same photo quality as the original with high-definition pigments, and costs a fraction of the price. See the compatible Epson 106 ink.

Is it compatible with your printer?

The Epson 106 ink is the one fitted to all the EcoTank machines of this photo family. They are refillable ink tank all-in-ones, designed to print photos and documents at a very low cost per page. If you have any of these models, this is your bottle:

• Epson EcoTank ET-7700
• Epson EcoTank ET-7750
• Epson Expression Premium ET-7700
• Epson Expression Premium ET-7750

The differences between variants are of format, not consumable: the ET-7750 models add A3+ size printing, while the ET-7700 stay at A4. The "EcoTank" and "Expression Premium" names correspond to the same hardware depending on the market where the machine was sold. In every case, the ink you need is exactly the same: the Epson 106.

The ink you need

These photo EcoTanks use a system of refillable ink bottles instead of cartridges: you refill the printer's tanks and keep printing for thousands of pages before topping up again. Our compatible Epson 106 ink replicates the original's high-definition formulation so you get the same sharpness in text and faithful colours in your photos.

The yield of an ink bottle is measured to the ISO/IEC 24711 standard, which standardises the calculation of pages per bottle on inkjet machines. Since the system refills by tank, each bottle goes far further than a traditional cartridge, and that's why the cost per page of these EcoTanks is among the lowest on the market. If you want to know how many bottles of each colour you need, check the product page and choose the colours that are running low.

How much printing costs you

The great appeal of the EcoTank range is the saving: by printing with refill bottles instead of cartridges, the cost per page falls drastically versus any cartridge machine. And if you add compatible ink to that, the saving is double. With our compatible Epson 106 you get the same print quality as with the original bottle, but paying only a fraction of the price.

Frequently asked questions

Does the compatible Epson 106 ink work in my EcoTank ET-7700 or ET-7750?

Yes. The Epson 106 is the official ink reference for this whole family (EcoTank ET-7700, ET-7750 and Expression Premium ET-7700/ET-7750). Our compatible version is formulated to work just like the original in these refillable tanks. If you're not sure of your model, you can check it in our printer finder.

Does it yield the same as the original ink?

The compatible Epson 106 ink replicates the original's high-definition formulation, with the same quality in document and photo. The yield of ink bottles is calculated to the ISO/IEC 24711 standard and, being a tank refill system, each bottle goes a very long way before you refill again.

Does using compatible ink void my printer's warranty?

No. Under article 120 of RLD 1/2007 (the General Law for the Defence of Consumers and Users), using compatible consumables does not void your printer's legal warranty. The manufacturer cannot force you to buy only its ink. You can review the details on our guarantee page.

How long does shipping take?

We ship within 24-48h to mainland Spain, and shipping is free on orders from €50. That way you have your ink ready before the tanks run dry.
