EcoTank ET-2803
The EcoTank ET-2803 runs on the same 522 ink as its ET-2800 sibling: four 65 mL dye bottles, black (T522120) up to 4,500 pages and each color up to 7,500 pages. Clever Supplies compatible 522 singles and the 4-bottle set are below — keyed fit, chipless, lifetime warranty.

|---|---|---|---|
| Epson T522120 (compatible) | Dye ink bottle, 65 mL | Black | 4,500 pages |
| Epson T522220 (compatible) | Dye ink bottle, 65 mL | Cyan | 7,500 pages |

ET-2803 Ink — Same 522 Shelf as the ET-2800 Epson lists the ET-2803's replacement ink identically to the ET-2800's: T522 inks, Black 4,500 pages, Color 7,500 pages per bottle (ISO/IEC 24712, Epson methodology), 65 mL bottles, dye ink in all four positions. If you run an ET-2800 and an ET-2803 in the same household, one shelf of 522 bottles genuinely covers both.
The boundary to respect is the family line, not the model line: the ET-2850 — despite the near-identical name — is a 502 printer and takes none of the bottles on this page.
Singles or the 4-bottle set, every Clever Supplies 522 bottle carries a lifetime warranty and 1-year free returns.
