EcoTank ET-4850
The EcoTank ET-4850's specification sheet names its replacement ink plainly: 502 — black 7,500 pages, color 6,000 pages, with pigment black for sharp documents. The compatible Clever Supplies 502 bottles below match those volumes and yields, with a lifetime warranty.

ET-4850 Ink Bottles — Verified From Epson's Spec Sheet Per Epson's ET-4850 specification sheet (CPD-60635R4), replacement ink is the 502 family: Black 7,500 / Colour 6,000 ISO pages. The black bottle (T502120, 127 mL) is pigment ink — Epson's sheet highlights that it produces extremely sharp text — and the three color bottles (T502220 / T502320 / T502420, 70 mL) are dye ink for vivid color output.
The ET-4850 is the big sibling of the ET-3850 and shares its ink shelf entirely. It does not share anything with the 522 family: if a listing tries to sell you 522 for this printer, it is the wrong bottle — wrong volume (65 mL), wrong black type (dye), wrong keying.
Restock with singles or the 4-bottle set; both are covered by a lifetime warranty and 1-year free returns.
