Epson EcoTank ET-15000 Review: Supertank Power for Small Business

Quick Verdict

The Epson EcoTank ET-15000 is a cartridge-free all-in-one that handles 13-by-19-inch paper, making it stand out from most office inkjet competitors. The supertank ink system cuts your cost-per-page to nearly a tenth of what you'd spend on cartridges, which, over two or three years, genuinely adds up. That said, the upfront price is higher than comparable cartridge-based machines, and it won't keep pace with laser-class speeds when you push quality to maximum. If your office prints a lot and occasionally needs wide-format output, it's easy to recommend. I'd score it around 4.4 out of 5.

What Is the Epson EcoTank ET-15000?

The EcoTank ET-15000 is an all-in-one Supertank printer — meaning it replaces traditional ink cartridges with four large, refillable ink tanks. You fill them from bottled ink rather than snapping in a cartridge, which dramatically reduces the cost per page over the life of the machine. It's positioned for small businesses and busy home offices that print enough to feel the pain of constantly buying cartridges.

Beyond the ink system, the ET-15000 packs print, scan, copy, and fax into a single unit. It connects wirelessly over 2.4 GHz Wi-Fi, via Ethernet for a more stable wired office network, or via USB for a direct computer hookup. The headline feature for me is the ability to feed paper up to 13 by 19 inches through the rear straight path — something most all-in-one printers in this price range simply cannot do.

Hands-On Review

I unboxed the ET-15000 on a Tuesday morning when the office was still quiet — the kind of low-pressure moment where setup feels less like a chore. The printer itself is larger than a typical home-office model; you will want to clear a permanent spot for it. The build feels solid, and the control panel tilts to a comfortable angle for standing use.

Initial setup took about twenty minutes, most of which was filling the tanks and waiting for the printer to prime its ink lines. Epson's bottle system is genuinely spill-resistant — you lock each bottle into its port and it seals automatically. Less messy than every other inkjet I've set up, and I appreciated that on a white desktop.

Print quality surprised me. I'd braced myself for the washed-out colour that sometimes plagues EcoTank models, but the Claria ET ink set holds up well. Documents come out crisp, colour presentations look professional, and borderless 11-by-17 photos have real punch — especially in the cyan and magenta channels. For a business machine, this is more than acceptable.

Speed is where you feel the trade-off. In draft mode, the ET-15000 churns out plain text pages at a reasonable clip — around 17 ppm for black according to Epson's specs. Switch to high-quality mode and things slow noticeably. By day three of having it on my desk, I'd learned which mode matched each task: draft for internal drafts, standard for client-facing documents, and high quality reserved for anything that was going out with a logo on it.

What surprised me most was the ADF. A 35-sheet auto document feeder on a printer at this price point is not guaranteed — many competitors trim it on cost. The ET-15000 has one, and it makes scanning a ten-page contract something that happens in the background rather than an exercise in tedium. Fax is a nice bonus; it's less critical in most modern offices, but for the occasional signed contract that needs to go out fast, it beats scanning and emailing.

The ink costs are the real story. Running the numbers on my own printing habits — roughly 400 pages a month between proposals, meeting handouts, and the odd marketing flyer — the ET-15000 would pay back its premium over a comparable cartridge model in under two years. That's not a marketing claim; it's simple arithmetic based on Epson's stated page yields and current ink bottle prices.

Who Should Buy It?

• Small businesses printing 300+ pages per month will feel the ink savings from day one and recover the upfront cost within 18–24 months.
• Home office workers who occasionally need wide-format output — 13-by-19-inch capability covers posters, architectural plans, and large presentations that standard letter/legal printers cannot.
• Anyone frustrated by constantly replacing cartridges will appreciate the Supertank's key-lock bottle system and the months of printing it enables between refills.
• Teams that share a printer over Wi-Fi or Ethernet will benefit from the solid network connectivity and walk-up LCD controls without needing a dedicated PC.

Skip this printer if you print fewer than 100 pages a month and expect it to pay for itself in ink savings. The upfront cost is real, and light users may take three years or more to see a return. A mid-range cartridge-based all-in-one would be the smarter move in that scenario.

Alternatives Worth Considering

If the ET-15000 doesn't quite fit your situation, here are two alternatives worth weighing:

• Canon MAXIFY GX7020 — also a Supertank all-in-one with comparable page yields. It maxes out at 11 x 17, so if 13 x 19 is non-negotiable for you, the ET-15000 wins. The GX7020 is worth considering if your office is purely Canon-aligned or if you prefer that brand's colour science.
• Epson WorkForce Pro WF-4830 — a cartridge-based alternative that costs less upfront. If you print lightly and want lower initial investment, this is a sensible option — just know that ink costs will catch up with you over time. It's better suited for light home office use than a busy small business.
• HP OfficeJet Pro 9740 — HP's wide-format all-in-one with strong mobile printing and decent page yields. It uses standard cartridges rather than a tank system, so the upfront price is lower but running costs are higher. Worth a look if you prefer HP's ecosystem and don't mind cartridges.

FAQ

Final Verdict

The Epson EcoTank ET-15000 earns its recommendation for small businesses and home offices that actually print — the Supertank system is not a gimmick, and the ink savings compound meaningfully over time. The ability to handle 13-by-19-inch paper in an all-in-one is genuinely rare at this price, and the ADF makes batch scanning and faxing painless in ways that simpler home printers simply cannot match. Print speed is the main trade-off, and the upfront cost will sting compared to cartridge models, but if you run the numbers honestly, the ET-15000 pays back comfortably within two years for any office printing at moderate volume. I'd buy it again without hesitation — and I've already moved our floor model from the test desk to the corner of the office where it belongs.
