Why they are important?
The International Organization for Standardization (ISO) announced yield testing and reporting standards for Monochrome Xerographic Engines under ISO/IEC 19752 in June 2004. Standards for Color Xerographic Engines were also announced under ISO/IEC 19798 and ISO/IEC 24711 in December of 2006. These standards are important to ensure that toner or ink yield reporting by different manufacturers will adhere to the same testing processes, making yields comparable across different products and manufacturers. This helps you evaluate consumable use and cost for printers or multifunction printers that you may be considering.
