Quick verdict

The Epson EcoTank ET-4850 is a full-featured supertank all-in-one built for households or small offices that print, copy, scan, and fax often enough that ink cost and paper handling really matter. At around $459–$472, it costs considerably more than entry-level EcoTank models, but in exchange you get an automatic document feeder, automatic duplex printing, a touchscreen, Ethernet, and fax — on top of the refillable ink tank system that keeps per-page costs low. Owner feedback is largely positive, with the main friction points being WiFi setup and a slightly noisier ADF than some expect.

Who this printer is for

1. Home offices or families that print, copy, scan, and fax regularly and want everything handled by one machine.
2. Anyone who wants automatic double-sided printing and an ADF for multi-page documents, rather than manual duplexing.
3. Buyers who print high volumes and want the lowest possible per-page ink cost over the life of the printer.
4. Households that want a wired Ethernet option in addition to WiFi for a more stable network connection.

What people love about it

• Ink bottles last a long time between refills, and running costs are consistently praised as a big improvement over cartridge-based printers.
• The touchscreen and automatic duplex/ADF combination make multi-page and double-sided jobs much easier than on lower-end EcoTank models.
• Setup is generally described as straightforward, especially when following the printer's QR-code guided walkthrough.
• Print quality holds up well for both documents and photos.

What buyers complain about

• Some owners recommend assigning the printer a static IP address to avoid it dropping off WiFi after network changes or router reboots.
• The automatic document feeder is described by some as "touch and go," occasionally misfeeding or requiring a second attempt.
• A handful of reviews mention the printer running slightly noisier than expected during scanning or ADF use.
• The higher up-front price is a bigger commitment than simpler EcoTank models, which won't make sense if you don't need fax or ADF.

Cheaper alternative: Epson EcoTank ET-2400

If you don't need scanning, copying, fax, or automatic duplex, our Epson EcoTank ET-2400 review covers a much cheaper print-only EcoTank model that still keeps ink costs low.

Upgrade pick

The ET-4850 already sits at the top of our EcoTank lineup for high-volume home and small-office printing, covering fax, ADF, automatic duplex, and Ethernet in one machine. If your priority shifts toward lower running costs on monochrome documents specifically rather than color and scanning, it's worth comparing against a laser option like our Canon imageCLASS MF3010 review.

Ink costs

The ET-4850 uses Epson's 502 EcoTank ink bottles — one larger 127mL black bottle plus 70mL bottles for cyan, magenta, and yellow. Owners consistently point to ink longevity as one of the printer's strongest selling points: a single fill is rated to last a good while even with regular use, which keeps the cost per page far below traditional cartridge-based inkjets, especially once you're printing hundreds of pages a month.

Setup tips

Follow the printer's QR-code setup guide for the fastest initial configuration, and if you experience WiFi dropouts, consider assigning the printer a static IP address on your router so it doesn't lose its network settings after a router reboot. If the ADF seems to misfeed, fanning multi-page documents before loading them can help.

Frequently asked questions

Does the ET-4850 support automatic double-sided printing?

Yes. Unlike entry-level EcoTank models, the ET-4850 includes automatic duplex printing for both copies and print jobs.

Does it have a fax function?

Yes, it includes fax support along with a 30-page automatic document feeder for multi-page scanning, copying, and faxing.

Can it connect over Ethernet as well as WiFi?

Yes, it supports wired Ethernet in addition to WiFi, which can help with connection stability in offices or homes with a lot of network interference.

Bottom line

The Epson EcoTank ET-4850 is one of the more complete supertank all-in-ones available, and it's worth the higher price if you actually need fax, ADF, and automatic duplex. Just consider a static IP if WiFi stability becomes an issue.
