What Ink Does the Epson EcoTank ET-2400 Use?

Quick answer: The Epson EcoTank ET-2400 uses Epson 522 ink bottles — T522120-S black, T522220-S cyan, T522320-S magenta and T522420-S yellow. Not Epson 502. We sell a compatible 522 four-bottle set. Free U.S. shipping applies to orders over $50, and orders placed by 4 PM ET ship the same day.

The ET-2400 is Epson's entry cartridge-free all-in-one — print, scan and copy with refillable tanks. It takes the same ink as the ET-2803 and ET-4800.

Epson EcoTank ET-2400 Ink Bottles at a Glance

Ink Bottle Color Approx. Yield
Epson 522 (T522120-S) Black ~4,500 pages
Epson 522 (T522220-S) Cyan ~7,500 pages
Epson 522 (T522320-S) Magenta ~7,500 pages
Epson 522 (T522420-S) Yellow ~7,500 pages

522 and 502 Are Not Interchangeable

This is the mistake worth avoiding. Epson uses uniquely keyed "EcoFit" bottle necks, so a 502 bottle will physically not fit a 522 tank. The two series look almost identical in listings and are frequently confused. Check the number before you order.

There is also no XL or XXL tier for EcoTank bottles — they come in one size. The yields above are what you get.

Your First Fill Will Not Reach These Numbers

Part of the ink that ships with the printer is consumed charging the print head during first-time setup. Epson says so explicitly. So the in-box ink prints noticeably fewer pages than a replacement bottle will — don't judge the running cost by the first tank.

The Waste Ink Pad: The Thing Nobody Mentions

Head cleanings send waste ink to an absorber inside the printer. Epson lists no user-replaceable maintenance box for the ET-2400 (the newer ET-2903 takes one, the C9398). When the waste-ink counter fills, the printer stops and Epson's remedy is service, which on a printer at this price usually means replacement. Third-party reset kits circulate, but they void the warranty and risk spilling waste ink, so we do not recommend them.

None of that changes the math: at roughly 4,500 black and 7,500 color pages per bottle, an EcoTank is still dramatically cheaper to run than any cartridge printer in its class.

What EcoTank ET-2400 owners ask

These are the questions that come up most for this printer on retailer Q&A pages, Epson's support pages and owner reviews, answered in our words.

How long will the ink that comes in the box last?

Epson says the box holds up to 2 years of ink, based on about 125 pages a month. The starter ink yields less than a replacement bottle because some of it primes the system.

The Windows 11 installer freezes during setup. Is that a known problem?

Yes. Epson lists it as a known issue on the ET-2400 support page and links a separate support article with the fix.

I set it up over USB. Can I switch to Wi-Fi later?

Yes. Epson's ET-2400 support FAQs cover moving from USB to Wi-Fi, and also cover Wi-Fi Direct and WPS setup.

My prints smear on glossy photo paper. Is that the ink?

Usually not. Epson's ET-2400 FAQs cover smearing on glossy paper and point to the paper type setting. Make sure the paper type you pick when printing matches the paper in the tray.

EcoTank ET-2400 quirks worth knowing

  • Epson's own pages disagree on the black yield. The ET-2400 page rates the 522 black bottle at 4,500 pages, while the newer ET-2903 and ET-2900 pages rate the same bottle at 4,700.
  • The same 522 bottles fit a long list of EcoTanks: the ET-2410, ET-2418, ET-2800, ET-2803, ET-2840 Special Edition, ET-4800, ET-4810, and the 2026 ET-1910, ET-2900, ET-2903 and ET-4903.
  • For an entry model, it has voice-activated printing and works with Epson's Smart Panel app for setup and printing from a phone.

Frequently Asked Questions

What ink does the Epson EcoTank ET-2400 use?
Epson 522 bottles: T522120-S black, T522220-S cyan, T522320-S magenta, T522420-S yellow.

Can I use Epson 502 bottles instead?
No. Epson keys the bottle necks so 502 will not physically fit a 522 tank. They are not interchangeable.

Is there an XL version of Epson 522?
No. EcoTank bottles come in a single size — about 65 mL each.

How many pages does a bottle print?
Epson rates the black bottle at about 4,500 pages and each color at about 7,500 on the ET-2400 page.

Can I use compatible ink bottles?
Yes. EcoTanks have no cartridge chip to authenticate, which is part of why they are so much cheaper to run.
