Epson 502 Ink Bottles: Common Questions

How many pages does a set of Epson 502 bottles print?

Epson rates a 502 black bottle at up to about 7,500 pages and each 502 color bottle at up to about 6,000 pages, so a full set of bottles lasts most home users well over a year.

Which printers use Epson 502 ink bottles?

Epson EcoTank ET-2750, ET-2760, ET-2850, ET-2980, ET-3760, ET-3843, ET-3850, ET-3950, ET-4750, ET-4760, ET-4850, ET-4950. Our Find Ink by Printer page has a guide for each model.

Will compatible Epson 502 bottles work in my EcoTank?

Yes. EcoTank bottles have no chip, so the printer cannot tell compatible ink from Epson ink; the bottle nozzle is keyed so it only fits the matching tank. Fill until the tank reaches the upper line, and if a bottle from us ever causes a problem, contact us and we'll replace or refund it under our 1-year guarantee.

Do I need to replace all four bottles at once?

No. Each tank is filled separately, so buy the color that is low. Black usually runs out first on home printers, which is why we sell it singly as well as in the 4-pack.
