The EcoTank ET-3760 offers Cartridge-Free Printing with easy-to-fill, supersized ink tanks. You can save up to 90 percent with low-cost replacement ink bottles - costing as little as 1 cent per color ISO page versus 20 cents with ink cartridges. Plus, you can get up to 2 years of ink with the included or a replacement ink set. Each replacement ink bottle set includes enough ink to print up to 7,500/6,000 pages (bk/clr) - equivalent to about 80 individual cartridges. That means less waste. Uniquely keyed EcoFit bottles make it easy to fill each color tank. Powered by PrecisionCore, this fast supertank printer offers a 150-sheet paper tray, 30-sheet ADF, voice-activated printing, and wired and wireless connectivity.
