Setup: Ink Filling
The Epson EcoTank system is designed for easy and mess-free ink refilling. Follow these steps to fill your printer's ink tanks:
- Open the ink tank unit cover on your Epson EcoTank printer.
- Identify the correct color tank for the ink bottle you are using. Each EcoFit bottle is uniquely keyed to fit only its corresponding color tank, preventing accidental misfilling.
- Unscrew the cap from the ink bottle. Do not squeeze the bottle.
- Insert the bottle into the correct ink tank. The ink will flow automatically into the tank. The bottle is designed to stop filling once the tank is full.
- Once the ink stops flowing, remove the bottle and securely close the ink tank cap.
- Repeat for all other colors as needed.
Important: Do not squeeze the ink bottle during refilling. The ink is designed to flow on its own. Store any leftover ink in its original box for future use.
