Epson T664 Magenta Ink Bottle with Sensormatic (70mL)

The Epson T664320S is a 70mL magenta ink bottle made for EcoTank printers, giving you the freedom to print up to 6,500 pages in rich and consistent color before it is time for another refill. The dye-based formula flows smoothly through the printhead so every presentation, photo, or homework assignment looks sharp and vibrant from start to finish.

A built-in Sensormatic chip lets compatible printers monitor ink levels with precision. You can confirm remaining ink at a glance and schedule refills in advance, preventing unexpected downtime during busy days at home or in the office.

The generous capacity helps families who tackle school projects, home offices that produce color reports, and small businesses that need marketing materials keep their printers running for months without interruption. Lower refill frequency translates to a reduced cost per page, which helps manage budgets without sacrificing quality.

Refilling is straightforward: insert the bottle into the EcoTank reservoir, let the ink flow, and you are back to printing within minutes. The T664320S works seamlessly with models such as the ET-2500, ET-2550, ET-4500, and other printers in the same series, so you can trust both fit and performance.
