Genuine OEM Epson® EcoTank ET-3930 Toners

Toner Buzz is an authorized Epson reseller.

The Epson EcoTank ET-3930 uses a T04D100 maintenance box to collect surplus ink from printing and print-head cleaning. The box fills as it absorbs this ink, and the printer stops printing when it reaches its limit.

Toner Buzz carries the genuine Epson T04D100 box for this maintenance job. Follow the printer message to change it when needed; the box collects used ink and is separate from bottles that refill the ink tanks.
