The Epson EcoTank ET-3950 is an all-in-one inkjet printer that uses refillable ink tanks rather than traditional cartridges. It features a 250-sheet paper tray and a 2.4-inch color display for navigation, and it supports automatic duplex printing. While you'll have to upgrade to the Epson EcoTank ET-4950 if you need a fax function, this model also supports dual-pass duplex scanning, a welcome addition for users who frequently handle large batches of documents. Connectivity options remain comprehensive, including USB, Wi-Fi, and Ethernet, as well as compatibility with Apple AirPrint and Mopria Print Service.
Our Verdict
If you're in need of a home printer designed for high-volume use and a fully featured scanner, the Epson EcoTank ET-3950 is an impressive choice. While it's designed for high-volume use and may be overkill for most families, it delivers incredible page yields at a very low cost for ink bottles. Its scanner is equipped with an automatic document feeder and even includes automatic dual pass duplex scanning, which is rare among this category of supertank printers. Its black-and-white document print quality is superb, and even if colors come out a bit washed when printing color documents, they remain totally serviceable. Finally, its color gamut is very good, and its color accuracy is improved, despite the reddish hue that permeates most photos. You should also keep in mind that it's relatively large, so ensure you have a suitable location to set it up.

The Epson EcoTank ET-3950 is a great option for small office environments. The printer delivers outstanding page yields while keeping maintenance demands minimal. You'll find the overall speed adequate for most daily tasks, unless you regularly print very large documents. Automatic duplex printing comes standard.

The Epson EcoTank ET-3950 is a reasonable choice if you're looking for a reliable printer that's always ready when you need it. As with any inkjet model, infrequent use can lead to clogged printheads; therefore, printing occasionally is recommended to prevent the ink from drying out. The printheads themselves aren't replaceable, but the printer's high-capacity flushing system can usually clear minor clogs and supports multiple deep-cleaning cycles without needing an ink refill. That said, if a clog is too severe for flushing to fix, there are very limited options to address it. Aside from this drawback, the printer's ink tanks deliver excellent page yields, meaning refills are rarely necessary. You'll also be able to easily print from virtually any device, thanks to the ET-3950's extensive connectivity options.

The Epson EcoTank ET-3950 prints at a reasonable speed and supports automatic duplex printing for added convenience. Photo printing, however, takes noticeably longer, and the first page is slow to print.

Slow to wake from an idle state.
The Epson ET-3950 delivers excellent results when printing black-and-white documents. Text is sharp and easy to read, graph lines look clean and precise, and overall clarity is high, with very few noticeable artifacts. That said, its color printing isn't quite as strong. Colors may appear slightly muted, and finer details may lack the same level of sharpness.

Popular Printer Comparisons
The Epson EcoTank ET-3950 or Epson ET-3958 is a great all-in-one inkjet printer that offers a comprehensive package to fulfill the needs of most users. It delivers outstandingly high yields that supertank printers have become known for, and its ink bottles are cheap. Its print quality is excellent, producing sharp documents. The scanner is also feature-rich. It features an automatic document feeder (ADF) and duplex scanning capabilities. If you're looking for a model with a fax function, Epson's otherwise identical Epson EcoTank ET-4950 is worth a look. These printers provide flexible all-in-one packages.

While competing laser printers like the Canon Color imageCLASS MF656Cdw/MF654Cdw can print and scan more detailed documents faster, they're less versatile, as they aren't well-suited for printing photos.
