Background

In December 2006, the International Organization for Standardization (ISO) body approved new standards for ink (ISO/IEC 24711) and color toner (ISO/IEC 19798) printer cartridge page yield measurements. These new standards complement the ISO/IEC 19752 yield standard for monochrome toner printer cartridges published in June 2004. The new ISO standards for ink and color toner cartridge yields clearly define the key attributes that affect yield and apply robust statistical analysis so all manufacturers can utilize the same methodology when measuring yield. Until now, printer manufacturers have not been able to use a uniform methodology to measure cartridge yields.

How are the tests performed?

The ISO/IEC 24711 and 19798 specifications stipulate that page yield is determined using a standard suite, printed in a controlled environment, with printer default settings. Because the printer environment can affect page yield, the testing environment is controlled at a temperature of 23.0C +/- 2.0C. The test suite, specified in ISO/IEC 24712, is designed to work with either A4 or 8.5x11" paper. The suite is a PDF file consisting of four typical customer pages and one diagnostic page is to be printed using the most recent version of a PDF reader.

Why are page yield standards important?

These page yield standards will help you make more informed purchase decisions by objectively and accurately evaluating print cartridge yields. The new ISO standards for inkjet and toner cartridge yields clearly define the key attributes that affect page yield and apply robust statistical analysis so all manufacturers can utilize the same methodology when measuring yield.
