"The WorkForce ET-3750 EcoTank all-in-one, powered by PrecisionCore, offers revolutionary cartridge-free printing with easy-to-fill, supersized ink tanks. It includes up to 2 years of ink in the box. That’s an incredible amount of ink — enough to print up to 11,200 pages, and equivalent to about 30 ink cartridge sets. Plus, it features auto-stop ink bottles with each color uniquely keyed for easy filling of each tank. And, you save up to 80 percent on ink with low-cost replacement bottles. The ET-3750 also offers a 30-sheet ADF, fast auto 2-sided printing, borderless printing up to 8.5"" x 11"", a 2.4"" color LCD and easy wireless printing from tablets and smartphones."
