You can purchase genuine Epson ink and paper from an Epson authorized reseller. To find the nearest reseller, visit global.latin.epson.com or call your nearest Epson sales office (website available in Spanish and Portuguese only).
The included ink bottles must be used for printer setup and are not for resale. The printer ships with full ink bottles and part of the ink from the first bottles is used to charge the print head. Yields vary considerably based on images printed, print settings, paper type, frequency of use, and temperature.
The ink bottles that came with your printer have a lower yield due to the ink charging process. This process is carried out the first time you turn on the printer and guarantees better performance. Do not load paper before refilling the ink tanks.
