The Epson EcoTank ET-3843 is a wireless color all-in-one supertank printer for home offices and families with steady print volumes. It includes a scanner, copier, automatic document feeder, automatic two-sided printing, a 250-sheet tray, and Ethernet alongside built-in Wi-Fi networking.

Deep-Dive Story & Problem/Solution

Buying Ink Should Not Be a Monthly Errand

Cartridge printers turn ink into a recurring chore and expense. For a household that prints school and work documents every day, cartridges can run out within weeks.

The ET-3843 uses refillable tanks. Replacement Epson 502 bottles yield about 7,500 pages in black and 6,000 in color, and each bottle set is equivalent to about 80 individual cartridges.

The printer adds the paper handling a home office expects: a 250-sheet tray, automatic duplex printing, and a document feeder for multi-page originals.

High-Capacity Ink and Paper

EcoFit bottles are keyed to prevent mistakes and fill without squeezing. The large front tray holds half a ream.

Connected and Convenient

Wireless and Ethernet networking, voice-activated printing, and the Epson Smart Panel app support printing and scanning from any device.
