Hello tony. Epson uses ISO/IEC 24711 tests to determine page yield. Your results can vary based on print settings, image size, paper type, etc. A new set of standard capacity T222 ink cartridges can print approximately 210 Black or 185 Color ISO pages. Alternatively, with a new set of T222XL ink cartridges, you can expect to print approximately 550 Black ISO pages. Please visit our official Epson Support page for more details.
