EcoTank Pro ET
EcoTank Pro ET is Epson's business supertank line, and it runs on a different ink idea than the home EcoTanks: the 542 family is pigment in all four colors (DURABrite ET). The black bottle (T542120) holds 127 mL and is rated up to 7,500 pages; cyan, magenta and yellow are 70 mL bottles at up to 6,000 pages each (ISO/IEC 24712). Find your model below and refill with Clever Supplies compatible 542 bottles, backed by a lifetime warranty.

EcoTank Pro ET Ink — All-Pigment 542 Bottles The eight EcoTank Pro models in this section share one ink family, the 542 — and one defining trait: pigment everywhere. Epson's Fact Sheet for the family headlines it "all-pigment ink for pro-quality prints," and its printer pages specify "4-color all-pigment" printing with DURABrite pigment ink. Business documents get the full benefit: sharp text, and color that resists water, smudging and fading far better than dye.
These printers are explicit about the requirement — Epson's own wording on the ET-5800 and ET-5850 is that the printer is designed for use with pigment inks only, and that dye ink may cause damage not covered by its warranty. That is why the 542 shelf matters: dye-based EcoTank bottles from the 502/522 families are not a substitute here, whatever the model numbers suggest.
Yields follow the pro pattern: black up to 7,500 pages, colors up to 6,000 pages each (ISO/IEC 24712, Epson methodology). Clever Supplies compatible 542 bottles are pigment inks matched to the family's volumes and keyed fit, chipless, and covered by our lifetime warranty with 1-year free returns.
