What is EN ISO 19798:2019

EN ISO 19798:2019, also known as the International Standard for Measuring the Yield of Toner Cartridges for Monochrome Printers, is a technical specification developed by the International Organization for Standardization (ISO). This standard provides guidelines and methodologies for measuring the yield of toner cartridges in monochrome printers.

Importance of EN ISO 19798:2019

EN ISO 19798:2019 plays a crucial role in ensuring transparency, reliability, and consistency in the measurement of toner cartridge yield. It allows consumers to make informed decisions regarding their printing costs and facilitates fair competition among manufacturers.

The standard specifies the test conditions and procedures necessary to accurately measure the number of pages that a toner cartridge can produce under specific circumstances. This helps customers gauge the efficiency and cost-effectiveness of different printer models, leading to better purchase decisions, reduced printing expenses, and minimized environmental impact.

Key Parameters for Measurement

EN ISO 19798:2019 defines several key parameters for the measurement of toner cartridge yield. These include:

Test Documents: The standard specifies a set of test documents that should represent typical everyday office printing. These documents are used to determine the average coverage area for calculating cartridge yield.

Testing Environment: The standard outlines the testing environment requirements, such as temperature and humidity, to ensure consistent and reliable results across different testing facilities.

Print Mode: Different print modes, such as draft, normal, or high-quality, are considered during the testing process to mimic real-life usage scenarios and provide a comprehensive understanding of cartridge performance.

Page Counting: EN ISO 19798:2019 provides guidelines on accurate page counting methods, including the exclusion of certain types of pages (e.g., blank or print-quality test pages) from the final yield calculations.

Benefits and Future Developments

EN ISO 19798:2019 brings numerous advantages to both consumers and manufacturers. For consumers, it ensures they can compare different printer models based on their performance and cost-effectiveness. Manufacturers can use the standard as a benchmark for further development and improvement of their toner cartridges.

The future will likely see advancements in the standard, considering the continuous evolution of printing technologies and the need for more accurate and reliable measurements. Keeping pace with these changes is crucial to keep EN ISO 19798:2019 relevant and valuable in the ever-evolving printing industry.
