Chips, Printer Messages & Installation
Epson 542 bottles use keyed EcoFit tips, so each color only fits its own tank. Stand the bottle upright on the matching fill port and let it drain; it stops automatically when the tank is full. Fill each color fully before priming, and only reset ink levels when the printer prompts you.
Questions about filling or priming? Contact us and we'll walk you through it.
Compatible vs. Remanufactured vs. Original
Original (OEM) cartridges are new from the printer brand and cost the most. Compatible ink, like this one, is newly manufactured from new components to the original's specifications and tested before shipping. Remanufactured cartridges are refilled originals. Castle Ink sells compatible (newly manufactured) toner and drums, and remanufactured inkjet cartridges.

Can I use a look-alike cartridge instead of Epson 542?
Epson 542 is all-pigment ink with keyed EcoFit bottles; it is not interchangeable with Epson 502, 522 or 512 bottles used by consumer EcoTank models.
Will this void my printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party or remanufactured supply. If a non-original cartridge directly caused damage, that specific repair might not be covered.
How long can I store it?
Store it sealed, at room temperature and out of direct sunlight, and use it within about 24 months for best results. Once opened, install it promptly.
When will my order ship?
Orders placed by 4 PM ET, Monday through Friday, ship the same business day from Long Island, NY, by USPS (2–5 business days). Expedited 1–2 day delivery is available at checkout, and shipping is free on orders over $50.
