The page yield of toner cartridges is typically tested according to the STMC international standard.

Testing uses specific sample prints (such as ISO/IEC 19752), and multiple printers are used for comparative printing under standard temperature and humidity conditions. Toner usage and the number of pages printed are recorded, and the average value is calculated.

Through repeated testing and random sampling, the stability and consistency of the toner cartridges under different environments can be verified.

The main factors affecting page yield include toner density, photosensitive drum performance, print coverage, and environmental conditions.

ACO compatible toner cartridges strictly adhere to the STMC testing process to ensure that the page yield of each batch is authentic and verifiable, providing customers with stable and reliable printing performance.
