## Description

Epson’s EcoTank replacement ink bottles offer thousands of vivid pages (1), 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 (2). Plus, these ink bottles feature exclusive autostop technology, with each color uniquely keyed for easy filling of each tank. Ideal for everyday printing, these ultra high-capacity inks mean you can go longer before replacing them for an unbeatable combination of value (3) and convenience. 1. 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 our official site. 2. 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. 3. Based on average monthly document print volumes of about 150 pages (ET-2700, ET-2750), 300 pages (ET-3700, ET-3750, ET-4750).

Review: The price is reasonable, and most importantly, this is a genuine product. I've been using it for 5 years now with no issues at all. Highly recommended and I'll be repurchasing soon.
Review: I buy only Epson brand ink for my office printer. The quality is excellent and a great value.

## Questions & Answers

**Q: I notice that they take great pains not to mention the minuscule size of these bottles.  Just how tiny are they?**
A: Yes, it is VERY hard to find the amount of liquid in different bottles. They often do not state size. Some are 60ml, some 70ml, some 127ml and other sizes.  I still like the ink but its very hard to compare price and size.

**Q: How much ml came in this bottle..?**
A: Hi dark_drakko,

The Epson 502 Cyan, Magenta, Yellow ink bottles contains 70 ml. each while the 502 Black ink bottle has 127 ml. Hope this answers your inquiry.  - The Epson Team

**Q: Why does the combo pack cost more than individual purchase?**
A: Packaging three bottles in a blister pack

**Q: Will this work with the ET-2720 model?**
A: Hi DANIEL ALVAREZ,

No. The T502 is not compatible with the Epson ET-2720. Use T522 when you order or purchase new ink bottles. To get good results on your printouts, please use Genuine Epson Ink.  Hope this clarifies your inquiry.   - The Epson Team
