EcoTank ET-2840 (Special Edition)
The EcoTank ET-2840 Special Edition shipped with an extra-generous ink box — three 65 mL black bottles plus one of each color — but its refills are the standard 522 family: black (T522120), cyan, magenta and yellow, all dye. Clever Supplies compatible 522 bottles below fit the ET-2840's keyed tanks; lifetime warranty included.

ET-2840 Ink — 522 Bottles, With One Yield Footnote The ET-2840 takes the same four 522 bottles as the rest of this section — T522120 black and the three 65 mL dye colors. One measurement note, stated plainly because Epson's own pages differ by model: Epson's US page for the ET-2840 rates replacement-bottle yields at 4,300 pages black / 7,300 per color on this printer, while the 522 family's standard rating (and most of its model pages) reads 4,500 / 7,500. The bottles are identical; the difference is the printer-side measurement on this PrecisionCore model. Our product pages carry the family standard; this page shows you both numbers because both are Epson's.
Everything else follows the family pattern: all-dye ink, keyed EcoFit nozzles, no chips. And the standing warning for the 28xx shelf: the ET-2850 is a 502 printer — none of these bottles fit it.
Every Clever Supplies 522 bottle carries a lifetime warranty and 1-year free returns.
