Genuine OEM Epson® EcoTank ET-3943 Toners

Toner Buzz is an authorized Epson reseller.

The T04D100 maintenance box serves a different purpose from refill ink in the Epson EcoTank ET-3943: it collects surplus ink from printing and head cleaning. Ink bottles supply the tanks, while the box holds ink that has already passed through the printer.

Toner Buzz carries this genuine Epson maintenance box for the ET-3943. It is the service part to change when the box reaches its absorbing limit and printing stops, rather than a pack of refill ink.
