EcoTank printers are refilled from ink bottles, not cartridges. Each model takes a specific bottle number, keyed so it only fits the right tank.
- Epson 502: ET-2750, ET-2760, ET-2850, ET-3750, ET-3760, ET-3850, ET-4850 and others. Epson 502 ink, for example 502 black.
- Epson 542 (EcoTank Pro): ET-16600, ET-16650 and other wide-format Pro models. 542 color combo pack.
The bottle number is on the printer's ink tank and in the manual. A black bottle prints thousands of pages, which is why EcoTank cost per page is so low.
All Epson bottles and cartridges: Epson ink.
