Epson EcoTank ET-2850

This pair is not the near-tie the EcoTank ET-2400-vs-ET-2800 matchup is. Here there is a real fork. The ET-2400 is the bare entry tank — cartridge-free, bottle-fed, no automatic duplex. The ET-2850 is the step-up that adds the things the entry model leaves out: it prints two-sided on its own, runs a faster black engine, and connects through Epson's Smart Panel app with less setup friction. So the literal answer is the easy one: the ET-2850 is the better machine, and it is worth the step up if your printing involves copying or double-sided pages.

Here's the thing the model numbers hide. Everything the step-up adds is workflow — speed, duplex, an easier first run. None of it is ink. Both tanks refill from the identical bottles at the identical yield, so the page you print costs the same whichever you own. Spend a minute on the feature gap; spend the rest on the one risk both carry and the question of whether a bottle-fed supertank fits how often you actually print.

The cheaper number is not the cheaper printer to run.

The features that justify the higher number

Start with what the step-up earns, because it is genuine. The ET-2850's headline addition is automatic duplex: Epson lists that Auto 2-sided printing helps save time and money. — the machine flips the page for you. The ET-2400 cannot. Epson's own note on the entry tank is blunt: it doesn't do automatic double-sided printing. You have to flip the paper manually. For anyone printing reports or double-sided documents, that single feature is the whole reason to pay more.

Speed and setup follow. The ET-2850 is rated to print Prints up to 10.5 pages per minute (ppm) in black and 5 ppm in color., a faster black engine than the entry tank, and it Offers mobile printing options, including the Epson Smart Panel App plus AirPrint — the connectivity owners say lands on the first tap. The ET-2850 also adds an automatic document feeder for copying stacks, where the ET-2400 leans on a features a rear-feed input tray that accepts up to 100 sheets and a flatbed alone. Those three upgrades — duplex, speed, the feeder — are the entire case for the higher model number.

One caveat on the feeder before you bank on it: owners report the ET-2850's scanner it wasn't that great because it doesn't scan doublesided and struggles with odd-sized receipts. It speeds up one-sided copying; it is not a two-sided scanning solution. Past those workflow gains, the two machines converge — and where they converge is the part that costs the most over time.

Where the step-up buys nothing

Here's the thing the spec sheet won't foreground: on running cost — the spine of any supertank — these two are the same machine. Both ship cartridge-free and quote the identical in-box rating. Epson prints, on the ET-2400 listing, that the included ink is that’s enough to print up to 4,500 pages black/7,500 color, and pitches that each ink bottle set is equivalent to about 80 individual ink cartridges. The ET-2850 fills from the same bottle set at the same yield. Cost-per-page is dead level. The faster, duplex-capable model is not the cheaper printer to feed.

Neither machine locks you to a subscription, either. Owners confirm of the ET-2850 that No subscription is required, you can just use the ink bottles that come with the printer, and the ET-2400 works the same way. That freedom from a monthly ink fee is the EcoTank line's whole pitch against a cartridge HP — and it travels with both numbers equally. We weigh that cost-per-page axis directly in our inkjet comparison criteria, and it is the line that should decide whether either tank belongs on your desk.

The running-cost case against cartridges is strong, and the same for both tanks. RTINGS' cost-per-print and page-yield testing puts bottle ink far below cartridge cost-per-page, and Consumer Reports' inkjet running-cost testing reaches the same verdict. Epson's EcoTank page stakes both machines on that thousands-of-pages yield. The savings are the reason to buy a supertank; the model number you choose does not change them.

Print quality lands in the same place on both. Owners describe color across the entry EcoTank line plainly: The color on the ET series is very muted. — fine for documents to read and file, short of a finished photo on either machine. The decision simply doesn't live on the page; for the Epson EcoTank line, cost-per-page and clog risk are where it lives. Our guide to refillable inkjet printers walks through who that suits before you buy in.

The risk the faster model can't outrun

Honestly, the most important thing about this pair is the thing neither model number fixes: idle clogging. Buy the ET-2850 for its speed and you still inherit the entry tank's worst failure mode.

A faster printer that won't print is no faster at all.

Liquid ink dries in the nozzles when an EcoTank sits unused. The printhead behind the ET-2400 and the ET-2850 is the same liquid-ink design, so the risk is identical — and owners of these exact machines manage it by force of habit, keeping a weekly reminder to run the nozzles and head off a clog before it sets. Recovery is not free: a blocked head spends ink on automatic cleaning cycles you never asked for, eating into the very yield you bought the tank to save.

Print in color at least once a week and the clog risk rarely bites either model. Leave one dark for a month and you can meet a blocked head the evening you finally need a page — and the faster engine on the ET-2850 prints nothing while it clears. That is the supertank tax: the savings are real for a steady printer and a fiction for an idle one. For the whole cartridge-versus-tank fork, our best supertank printers roundup lays out where each option earns its place.

Epson EcoTank ET-2850

Entry tank, step-up tank, or neither?

Because the ET-2850 is the step-up and the ET-2400 the bare entry tank, "who buys which" comes down to one question — how much workflow you need — wrapped around the bigger one of whether a bottle-fed EcoTank suits you at all. If you're eyeing the ET-2400 to save, be honest about how often you'll miss the auto-duplex and the feeder. If you're paying up for the ET-2850, accept that you're buying speed and convenience, not a cheaper page. Here is how it resolves.

The direction you came in from changes the answer more than it does for the closer EcoTank pairs. If you're coming from the cheaper ET-2400 and wondering whether the ET-2850 is the real upgrade, the answer is yes for a working household — for ET-2400 owners who copy or print double-sided, the auto-duplex and the faster engine are tangible daily gains, not marketing. Looked at from the ET-2850 side, the honest question back to anyone eyeing the lower-numbered ET-2400 for less is how often you copy or print double-sided: skip those tasks and the entry tank prints the same pages for the same ink money, and you pocket the difference. Either way the bottle yield and the clog risk travel with you.

Step up to the ET-2850 if…

…you copy paperwork or print double-sided. The Epson ET-2850's automatic duplex, its automatic document feeder, and its faster 10.5-ppm black engine are the whole reason to pay more, and for a home office that scans and prints reports they save real time every week. The easier Smart Panel setup is a bonus on top. Going in, accept the trade: you're buying a better workflow on the same ink economics, not an escape from the clog cadence every EcoTank shares.

Buy the ET-2400 if…

…you print mostly single pages and want the cheapest honest way into Epson's cartridge-free line. The ET-2400 sips ink at the same cost-per-page as the ET-2850, so for a buyer who never needs auto-duplex or a feeder it is money saved for nothing that touches running cost. It best suits the cartridge refugee — someone leaving an HP DeskJet behind — who prints color weekly and wants out of the cartridge tax without paying for office features they won't use.

Skip both if…

…you print rarely, or you need true office volume. A twice-a-year household should not buy either supertank — the clog risk outruns the ink savings, and a budget cartridge all-in-one is the calmer pick. If you need steady office throughput, two-sided scanning, or fax, neither entry EcoTank delivers it; an Epson WorkForce or a color laser is the right room.

The ET-2400 and ET-2850 are for the weekly-or-more home printer escaping the cartridge trap — at any lighter use, both are the wrong tool.
