Epson EcoTank ET-4850

Here's the thing: this is the rare EcoTank step-up where the cheaper model is the answer. The Epson EcoTank ET-4800 and the EcoTank ET-4850 are both office supertanks — they carry the same scanner, copier, fax, automatic document feeder and wired Ethernet, and they refill from the same bottles. Whichever you pick, you have already walked out of the cartridge tax. So the question is never which one saves more on ink, because they save the same. It is whether the dearer rung's extra speed earns a price step that runs to roughly three times the cheaper one.

The split is short. The ET-4850 prints faster on paper and quotes a sharper resolution; the ET-4800 does the same jobs a touch slower for a fraction of the money. That is most of the gap. The rest of this page is about why the office features you might think you are buying with the step-up are already on the cheaper model — and when the speed is worth paying for anyway.

At a Glance

The office stack is the same on both

Start where buyers assume the price gap lives, because it does not live there. People expect the dearer EcoTank to be the one with the document feeder and the network jack. Both have them.

The ET-4800 is, in Epson's own listing, an Epson EcoTank ET-4800 Wireless All-in-One built around scanner, copier, fax, ADF and Ethernet. The ET-4850's listing describes the dearer model the same way — a cartridge-free supertank with the identical scanner, copier, fax, ADF and Ethernet roster. Both even add automatic two-sided printing; an ET-4800 owner confirms The printer dues Dual-Sided Print. So the office plumbing that separates these from the cheap EcoTanks is on the cheaper of these two as well.

Then the ink, which is the spine of any supertank. Both ship cartridge-free, the ET-4800 leading with Innovative Cartridge-Free Printing and the ET-4850 matching the same bottle system. RTINGS' cost-per-print and page-yield testing puts that bottle-fed bracket far below any cartridge office printer, and we lay out the full scoring logic in our comparison criteria for inkjet printers. On the number this site organizes around, these two are level.

Where the dearer rung actually pulls ahead

With the office stack and the ink off the table, the gap narrows to two specs: speed and resolution. That is the honest list.

The ET-4850 is rated to Prints up to 15.5 pages per minute in black and 8.5 in color, quick enough for real document runs, where the ET-4800 carries a slower rating for the same kind of page. It also quotes a finer Prints at a 4800 x 1200 resolution for crisper text and graphics, and its control panel is the larger of the two. Useful upgrades — but a faster engine and a sharper number, not a new job the ET-4800 cannot do.

And the rated speed comes with the usual caveat. One ET-4850 owner found that It prints slower than specified in everyday use, the gap between brochure throughput and real-world pages that page-yield and speed claims routinely hide. Consumer Reports' inkjet running-cost testing finds the same across the category: rated speeds are best-case, not typical-case. So the speed advantage the ET-4850 charges for shrinks a little once the printers leave the spec sheet.

The catches both rungs share

One set of failure modes ignores the price tag: these are the same EcoTank family, so they inherit the same trouble. Paying more does not buy you out of any of it.

Idle clogging is the headline risk on both. Liquid ink dries in the nozzles when either printer sits, and the machine spends ink on cleaning cycles to recover. On the ET-4800 it can get bad — one owner reports Constantly not printing the text. Have to clean out nozzles, align as a regular chore. ET-4850 owners are warned the same way: you want to avoid ink drying in the pipes if you print infrequently. The fix is identical and free — print in color weekly. We track that idle-clog risk in our safety and known-risks guidance.

The automatic feeder is the second shared soft spot. On the ET-4800, one owner found The scanner is very slow and the amount of sheets you can put into the autofeeder is light before jams start, and the ET-4850's feeder draws the same slow-and-jam-prone complaint. And the first tank fill on the ET-4800 is a patience test — an owner reports That will take you over 2 hours to get all loaded. Budget that on either machine the first time you prime it.

Print quality, finally, is a wash — and the same honest limit applies to both. EcoTank office output is muted by design; an owner is blunt that The color on the ET series is very muted. Both the ET-4800 and ET-4850 are document machines, not photo printers, and they post the same kind of owner satisfaction — the ET-4850 holds a rating: 4.2 across 13 Amazon reviews. Print quality is not where this decision lives; for the Epson EcoTank office line, cost-per-page is a tie and the fork is speed against price.

So which EcoTank — save or pay for speed?

Because the ink math is a tie and the office stack is shared, "who buys which" comes down to one question: is the ET-4850's faster engine worth roughly triple the ET-4800's price for how you print? If you are coming from a clogged or bricked cartridge printer, either EcoTank is the upgrade, and the cost savings land the same on both. The split is purely speed against money.

Buy the Epson ET-4800 if…

…you want the full office supertank for the least money — which is most buyers. The ET-4800 gives you the same scanner, copier, fax, ADF, Ethernet and auto-duplex as the dearer model, the same cartridge-free bottle ink, and the same low cost-per-page, all for roughly a third of the ET-4850's sticker. You give up only rated speed and a resolution number, neither of which a typical household notices. For homework, labels, returns and light photo work, this is the honest pick, and the savings against a cartridge office printer are the same as on its pricier sibling. We weigh where the whole EcoTank line sits in our guide to Epson inkjet printers.

Buy the Epson ET-4850 if…

…print speed is your real bottleneck. A busy home office that runs long black-text batches against the clock will feel the 15.5-ppm engine earn part of its gap, and the sharper 4800 x 1200 resolution helps if you print fine text or detailed graphics daily. You pay roughly three times the ET-4800 for a faster machine with the same features, so this only makes sense when throughput, not capability, is the thing slowing you down. Read the full case — including the reliability caveats — in our Epson ET-4850 review.

Skip both if…

…you print rarely, or you only ever print black text. A printer that sits idle for weeks fights you on either rung — a color laser is the calmer pick for sporadic use. And if your output is purely mono documents, a mono laser is faster, cheaper to run, and immune to clogs; the EcoTank office machines earn their keep when you need color, scan, copy and fax in one box.
