Filling & Printer Messages
Filling: open the ink tank cover and the cap for one color. Remove the bottle cap, stand the bottle upright on the matching fill port (each 542 tip is keyed to its color) and let it drain; it stops automatically when the tank is full. Replace the caps, then follow the on-screen prompt to confirm which colors you refilled.
Printer messages: EcoTank printers have no cartridge chips, so there is no "non-genuine cartridge" lockout. Only reset ink levels when the printer asks, after filling.

Frequently Asked Questions
Which printers use Epson 542 ink?
Epson EcoTank Pro ET-5150, ET-5170, ET-5180, ET-5800, ET-5850, ET-5880, ET-16500, ET-16600 and ET-16650, and WorkForce ST-C5000, ST-C5500, ST-C8000 and ST-C8090.
How many pages does Epson 542 ink print?
About 7,500 pages per black bottle and 6,000 pages per color bottle, based on Epson's ratings for the genuine ink.
Can I use 502 or 522 bottles in a 542 printer?
No. Each EcoTank bottle number has a differently keyed tip.
Will compatible ink void my Epson warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used third-party ink. If third-party ink directly caused damage, that specific repair might not be covered.
How long can I store it?
Keep bottles sealed, upright, at room temperature and out of direct sunlight, and use them within about 24 months.
When will my order ship?
Orders placed by 4 PM ET, Monday through Friday, ship the same business day from California, by USPS (2–5 business days). Expedited 1–2 day delivery is $25, and shipping is free on orders over $50.
