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.
