Compatible Epson 664 ink: EcoTank models and refilling

For Epson 664 EcoTank, first check references 664 in the manufacturer documentation for your exact model and sales region.

Before ordering, verify the full printer model, the region, and the precise product reference.

How to refill the tank and check ink-level notices

Follow the refill instructions for your exact Epson model and bottle. These general steps do not replace the fill-level markings or safety notes in its manual.

• Open the tank cover and remove the cap for the corresponding colour.
• Uncap the bottle and pour it in without forcing until you reach the tank's maximum fill line.
• Close the cap and cover firmly. Always respect the maximum mark to avoid overflows.

If a low-ink notice appears after refilling, consult your model’s procedure before resetting a level or cleaning the printhead. Not every printer reports or resolves notices in the same way; do not assume a chip issue or a universal mandatory reset.

Declared yield and cost comparison

The current Startoner listing declares up to 4,000 pages for its black 664 bottle. This is a seller claim, not an independent test; no yield for every color has been verified here. Epson uses a different method for its original-ink yield, so do not equate the figures automatically. The yield shown on a Startoner product page describes that seller product and must not be confused with the manufacturer’s figure for an original supply. Actual pages vary with document content, coverage, and print jobs. Compare current prices using like-for-like yield assumptions, and check which measurement method supports each stated number.
