Yield: Every cartridge should state the number of pages that it will produce per toner cartridge. Our compatible cartridges have the same or even more page yield than original toner cartridges.

Image Quality: On testing our remanufactured toner cartridges we evaluate the clarity of the output particularly when testing color cartridges.

Grey Scale: These measures the standard deviation between the different toner levels applied to the page. At the moment there are no industry standards for the Grey scale but when testing our remanufacturer makes sure there is a difference in the percentage of the scale.

Density: When talking about density we test the "blackness" of the toner ink.

Reliability: All the testing performed is to ensure that a cartridge will perform to its end of life without any defects or failures.
