## Description

Epson’s new EcoTank replacement ink bottles offer thousands of vivid pages (2), while delivering genuine Epson quality. When it comes time to buy more ink, you save up to 80 percent on low-cost replacement ink bottles (3). Ideal for everyday printing, these ultra high-capacity inks go longer between refills for an unbeatable combination of value (1) and convenience. 1. Based on average monthly print volumes of about 150 pages (ET-2500, ET-2550, ET-2600, ET-2650, ET-4500). | 2. Replacement ink bottle yields based on the ISO/IEC 24712 pattern with Epson’s methodology. Actual ink yields will vary considerably for reasons including images printed, print settings, temperature and humidity. Yields may be lower when printing infrequently or predominantly with one ink color. All ink colors are used for printing and printer maintenance, and all colors must be available for printing. For more information, visit www.epson.com/inkinfo | 3. Savings comparison based on the purchase cost of replacement ink bottles and the cost of enough cartridges to achieve the total page yields of the bottles using the manufacturers' online prices and yields for the highest-capacity cartridges for the best-selling similarly featured consumer inkjet printers priced at $499 or less per NPD, July 2016. Actual savings will vary based on print tasks, print volumes and usage conditions.

## Questions & Answers

**Q: My 2650 came with 664 bottles, is this the same?**
A: Hi Heavyoak, 

Yes. The Epson T664120 EcoTank Black Ink Bottle is compatible with Epson Expression ET-2650 EcoTank. Hope this helps!

-The Epson Team

**Q: How does this work?  Do you put the ink in the regular cartridge some way?**
A: Hi, no this is not to refill a regular cartridge. I have an Epson ET-2550. The ink bottles refill the tanks. This is the best printer!  It costs a litlle more upfront but the cost savings from not buying cartridges is huge!! We print a lot and i have only to refill the tanks maybe once a year.  The bottles much cheaper than cartridges.

**Q: Can i use it for image transfer on t-shirts?**
A: No. This is not sublimation ink.

**Q: Is it pigment ink? I need it for epson wf-c5790 printer**
A: This is dye based ink, for wf-c5790 you would need Epson T-902 or T-902XL.
