Hello myprintreview. Epson uses ISO/IEC 24711 tests to determine page yield. The ET-2170 can print approximately 20 Black ISO ppm. A standard capacity T532 Ink Bottle can print approximately 6,000 pages. The printer includes a paper cassette tray and a paper feed. You can expect to load 250 sheets of 8.5" x 11" plain paper and ten No.10 sized-envelopes in the machine. Please note that Paper capacity can vary based on page size, weight, and type. For additional details on paper loading capacity, please see the User's Guide on our official Epson Support page. Regards, Kevin - The Epson Team.
