Epson T664 Cyan Ink Bottle with Sensormatic (70mL)

The Epson T664220S is a 70mL cyan ink bottle created for EcoTank printers that need frequent, economical refills without the waste of traditional cartridges. It arrives sealed and ready to pour, so you can top up your tank quickly and get back to printing.

Each bottle holds enough dye-based ink to produce around 6,500 pages, which means fewer interruptions whether you are running a busy home office, a classroom, or a small business workstation. Because the ink flows directly into the built-in tank, you avoid the cost and clutter that come with disposable cartridges.

The dye formula lays down crisp text and brilliant color that stands out on everyday documents as well as borderless photos. If you regularly print marketing flyers, homework assignments, or family snapshots, the consistent cyan tone keeps graphics looking balanced and professional.

A Sensormatic tag is integrated into the packaging so organizations that rely on electronic article surveillance can monitor inventory with less manual counting. This helps retail stores and managed print services track stock and prevent loss.

Compatibility is straightforward. Use the bottle with popular EcoTank models such as the ET-2500, ET-2550, ET-4500, and ET-4550, along with several others in the same series. The keyed nozzle design aligns with the correct tank opening, making the refill process clean and nearly spill-free even for first-time users.
