Epson EcoTank ET-3850
Epson lists the ET-3850 as discontinued and names the EcoTank ET-3950 as its replacement. Its page stays up for comparison; the figures are the maker’s published ones for this model.
Where the two-digit EcoTanks are household printers with an office feature bolted on, the ET-3850 is built the other way round. It has a real 250-sheet enclosed cassette instead of a rear feed, Ethernet as well as Wi-Fi, a 2.4-inch touchscreen, and a print engine rated 15.5 ISO pages a minute in black — half again faster than the ET-2850 for a hundred dollars more. The ink is the same 502 set, so the running cost does not change: a third of a cent a mono page, a little over a cent for a page using all four inks. A 30-sheet document feeder sits on the lid as well, so the only hardware the ET-4850 above it adds is a fax modem. If you never fax, the ET-3850 is the better value of the two.

In its favour
- An enclosed cassette keeps 250 sheets flat and dust-free, which the rear-feed models cannot do
- 15.5 ISO ppm black makes a long document bearable
- Wired Ethernet, which most printers at this price dropped years ago
- Same third-of-a-cent mono page as the cheaper 502-based models
- Touchscreen is responsive enough to drive copies without a phone
Against it
- The feeder scans one side only, so a two-sided original goes through twice
- No fax, which is the one thing the ET-4850 adds
- Taller than the two-digit models, with the cassette below and the feeder on the lid
- Photo output is good for a four-ink printer but not close to the six-ink ET-8500
What owners say
