ET-4810 Ink — 522 Family, Model-Measured Yields Noted Epson's product data for the ET-4810 describes its ink system completely: Ink Technology — Dye Ink, with Black, Cyan, Yellow and Magenta each listed as dye, in 65 mL bottles. The bottle shelf is the standard 522 set: T522120, T522220, T522320, T522420.
The yield footnote, honestly stated: Epson's US page for this model rates replacement bottles at 4,300 pages black / 7,300 per color, while its Australian page and the family standard read 4,500 / 7,500. Same bottles, printer-side measurement difference on this newer model. Our product pages use the family standard; both figures are Epson's, and both are shown here so you can judge.
Refill singles as needed or reset with the 4-bottle set. Every Clever Supplies 522 bottle carries a lifetime warranty and 1-year free returns — and none of them fits the 502-family ET-4850, despite the similar name.
