Compatible Epson 102 for EcoTank: guide, installation and savings
Actualizado 18 julio 2026Share
If you have an Epson EcoTank printer and want to top up the ink without paying the price of the original, the compatible Epson 102 is the reference you need. Here we explain which models it works with, how to load it, what to do if the printer "doesn't recognise the cartridge" and what real savings you can expect.
What the Epson 102 is and which printers it works with
The Epson 102 is an ink designed for the EcoTank refillable tank system (despite being catalogued as toner, it is in fact liquid ink). Our compatible version is manufactured under the ISO 9001 quality standard and is suitable for exactly these models:
- Epson EcoTank ET-2700
- Epson EcoTank ET-2750
- Epson EcoTank ET-3700
- Epson EcoTank ET-3750
- Epson EcoTank ET-4750
If your model isn't on this list, take a look at our other EcoTank references: the compatible Epson 106, the compatible Epson 104 or the compatible Epson 103, each for its own printer family.
How to load it and what to do if it "doesn't recognise the cartridge"
In an EcoTank system you don't slot in a cartridge: you refill the tank for the corresponding colour. The basic procedure is:
- Check which colour each tank corresponds to before you start.
- Open the tank cover, remove the cap and pour in the ink without going over the maximum fill line.
- Close the cap and cover firmly, and follow the ink level reset process on the panel that the printer prompts you to do.
Because the EcoTank works with tanks rather than per-cartridge chips, the "cartridge not recognised" warning is uncommon compared with other systems. If, after refilling, the printer still shows a colour as empty, switch it off and on again to force a new reading, manually confirm the ink level reset from the maintenance menu and check that the tank is properly filled and the cap closed. These issues are usually down to the internal level count, not a fault with the ink.
Yield and savings compared with the original
An ISO 9001 compatible ink aims to deliver print densities and colours equivalent to what you'd expect in home and office documents and photos. The main advantage is the cost per page: by topping up with a compatible ink you pay considerably less for the same amount of ink, which is especially relevant in an EcoTank system, where you print large volumes between refills.
