Overview

The Epson T664220-S is a genuine cyan ink bottle engineered for Epson's EcoTank line of refillable inkjet printers. Unlike traditional cartridge-based systems, the EcoTank design uses built-in reservoirs that you fill directly from the bottle, eliminating cartridge waste and dramatically reducing per-page printing costs. This ultra-high capacity bottle is rated to produce thousands of pages, making it an economical choice for homes and offices with moderate to high print volumes.

The bottle features Epson's keyed nozzle system, which ensures the tip fits only the cyan ink tank — preventing accidental cross-color fills and minimizing spill risk during refilling. As a genuine Epson consumable, it is formulated to deliver accurate, vibrant cyan output and maintain the long-term reliability of your printhead. It is compatible with select EcoTank models including the ET-2500, ET-2550, ET-2600, ET-2650, ET-4500, and ET-4550 series, so confirming your printer model before purchase is recommended.
