The Epson T664 is a cyan dye-based ink designed specifically for the EcoTank L-series inkjet printers. Each 70 ml bottle provides enough volume to print approximately 7,500 color pages, making it a practical choice for those who handle high-volume printing tasks without needing frequent replacements. This ink is compatible with a wide range of models, including the L100, L110, L120, L121, L132, L1300, L200, L210, L300, L3050, L355, L400, and L550. The plastic bottle features a specialized nozzle that allows you to refill the printer tanks cleanly and easily, reducing the risk of spills during the process.
