Epson EcoTank ET-3850 Review (2026): Best Cartridge-Free All-in-One?

The Epson EcoTank ET-3850 is a cartridge-free all-in-one that replaces expensive ink cartridges with refillable tanks. Included with the printer are enough ink bottles to print approximately 14,000 black pages and 5,200 color pages — roughly two years of heavy home use without buying a single cartridge. At ~$279 upfront, it costs more than budget inkjets, but for anyone printing 200+ pages per month, the ET-3850 pays for itself in under a year. This is the anti-subscription printer — no lock-in, no monthly fees, just refill the tanks when needed.

Who Is the Epson EcoTank ET-3850 For?

The ET-3850 is designed for high-volume home users and small offices — families with school-age kids who print constantly, home businesses printing invoices and reports, or anyone who has been burned by expensive cartridge replacements in the past. The included ink lasts approximately 90 weeks at Epson's rated yield (200 pages/month average). When you finally do run out, replacement bottles cost about $13 per color and $9 for black — yielding another 7,500 black pages and 6,000 color pages per set. That works out to about $0.004 per page all-in, including color.

Who it's NOT for: very light users printing fewer than 50 pages per month. At that usage level, the upfront cost takes 3+ years to recoup. The HP ENVY 6055e with Instant Ink will be cheaper overall for light users.

Print Quality

The ET-3850 uses Epson's PrecisionCore printhead technology with 4-color dye ink (CMYK). Print quality for documents is excellent — crisp black text, vibrant color charts and graphs. Photos printed on Epson photo paper look very good for an inkjet all-in-one, though dedicated 6-ink photo printers edge it out for professional-level color accuracy. For home and office use, the output is more than adequate: sharp, colorful, and consistent.

One thing to note: like all inkjets, the ET-3850 can experience head clogging if left unused for extended periods (2+ months). Epson's maintenance routines handle this well, but it's worth printing a test page every few weeks if you're an irregular user.

Ink Economics — The Main Selling Point

This is where the EcoTank shines. The included ink yields approximately:

• 14,000 black pages (~$279 printer ÷ 14,000 pages = $0.020/page for black alone)
• 5,200 color pages (mixed usage)

Once you exhaust the included ink, a replacement set (4 bottles: black + CMY) costs about $45 and yields another 7,500 black and 6,000 color pages. That's approximately $0.004 per page for color printing — cheaper than most laser printers on a per-page basis and dramatically cheaper than cartridge-based inkjets. For a family printing 300 pages per month, the ET-3850 saves roughly $40–60 per month compared to buying HP 67XL cartridges retail.

Features: ADF and Duplex

The 30-sheet ADF handles multi-page scanning without manual page flipping — excellent for digitizing documents, tax paperwork, or old receipts. Automatic duplex printing reduces paper consumption and is genuinely convenient for two-sided reports. The 2.4-inch color LCD is functional but not a touchscreen — navigation uses physical buttons. Ethernet is included alongside WiFi, making this a solid choice for small office network printing.

How It Compares

The ET-3850 sits between the entry-level ET-2803 (no ADF, ~$199) and the ET-4850 (adds fax, ~$349). For most home users, the ET-3850 hits the sweet spot: ADF for scanning, duplex for two-sided printing, and enough speed for daily use. The Brother MFC-J4335DW INKvestment Tank is a comparable alternative with a larger ADF (50 sheets vs 30), but Epson's per-page cost is still lower.

Should You Buy the Epson EcoTank ET-3850?

Buy it if: You print 200+ pages per month and want the lowest possible per-page cost without subscriptions. The ET-3850 pays for itself in under a year for high-volume users and delivers excellent print quality along the way. It's the best cartridge-free all-in-one for families and small home offices.

Skip it if: You print fewer than 50 pages per month, need laser-level speed (20+ ppm), or want the smallest possible footprint. Light users should look at HP Instant Ink options; speed-focused users should buy a Brother laser instead.
