EcoTank ET-2400
The EcoTank ET-2400 is the entry point of the 522 family: a cartridge-free all-in-one whose four tanks refill with 65 mL dye bottles — black (T522120) up to 4,500 pages, and cyan, magenta and yellow up to 7,500 pages each. Clever Supplies compatible 522 bottles below are keyed for the ET-2400's tanks and carry a lifetime warranty.

ET-2400 Ink — 522 Bottles, All Four Colors Epson's ET-2400 documentation lists its replacement ink plainly: 522 bottles across the board, with ISO yields of 4,500 pages black and 7,500 pages per color (ISO/IEC 24712, Epson methodology). All four inks are dye-based — the 522 family has no pigment black — and all four bottles are 65 mL.
As the family's entry model, the ET-2400 is where many owners meet EcoTank for the first time, so the one rule worth learning now: your family is 522, not 502. The similarly named ET-2700 takes 502 bottles, which are keyed differently and will not fit your tanks.
Refill single colors as they run down, or use the 4-bottle set for a full reset. Every Clever Supplies 522 bottle carries a lifetime warranty and 1-year free returns.
