Hello Mugten. Epson uses ISO/IEC 24711 tests to determine page yield. Please note that your results can vary based on print settings, image size, paper type, etc. A new set of standard capacity Epson Ink Cartridges can print approximately 240 Black or 360 Color ISO pages. Alternatively, with a new set of High-capacity Epson Ink Cartridges, you can expect to print approximately 500 Black and 830 Color ISO pages. Please visit our official Epson Support page for more details. Regards, Kevin - The Epson Team.
