EcoTank ET
EcoTank ET printers are Epson's cartridge-free supertank line for homes and small offices, and every model in this section refills from the same 522 ink bottle family: four 65 mL dye bottles — Black (T522120), Cyan (T522220), Magenta (T522320) and Yellow (T522420). Note the family's unusual yield pattern: black is rated up to 4,500 pages while each color runs up to 7,500 pages (ISO/IEC 24712). Find your model below and refill with Clever Supplies compatible 522 bottles, backed by a lifetime warranty.

EcoTank ET Ink — The All-Dye 522 Family The eight printers in this section span entry models (ET-2400, ET-2720) through office-leaning machines (ET-4800, ET-4810), but their ink shelf is a single family: 522. All four bottles are dye ink — including the black, which is the family's biggest difference from the 502 line, where black is pigment. All four bottles are 65 mL, and the colors outlast the black: up to 7,500 pages per color against 4,500 for black, on the ISO/IEC 24712 pattern with Epson's methodology.
The trap in this neighborhood is model numbers, not bottles. The ET-2720 (522) sits next to the ET-2700 (502); the ET-2800 (522) next to the ET-2850 (502); the 47xx band splits between families. A 502 bottle will not seat in a 522 printer and vice versa — the EcoFit keys differ by family. Read the badge on your printer, match it to a model page below, and the ink takes care of itself.
Clever Supplies compatible 522 bottles match the genuine 65 mL fill and keyed fit, carry no chips, and are covered by our lifetime warranty with 1-year free returns.
