There are different industry standards for testing toner cartridges that provide varying perspectives on performance and page yield. The ASTM F1856-04(2009) standard involves disassembling cartridges before testing to directly weigh toner fill, but this does not reflect the actual lifespan. It also does not define the page coverage percentage in a standardized way. ISO/IEC 19752 and 19798 standards use a predetermined test page that can be used on any printer, and test cartridges for their full lifespan. The latest ISO/IEC 24712 standard provides a suite of color test patterns and sets strict guidelines to minimize variables and better evaluate cartridge performance.

1. Testing Toner Cartridges against Industry Standards
Different test standards and conditions give different perspectives on cartridge performance, image quality
and page yield.
ASTM F1856-04(2009) Standard Practice for Determining Toner Usage is a cost per page and yield analysis.
This ASTM protocol requires cartridge disassembly prior to testing in order to weigh the toner fill. By
calculating the difference in weight, in grams, befo
coverage, the approximate “page yield,” in number of pages per gram of toner consumed, can be determined.
Although this method is quick and simple, it does not reveal the actual life of the cartridge. One

Another issue is that not defining the 5% page coverage to a specific or standardized test pattern (or,
preferably, to a suite of patterns) leaves room for error. Test pa
ghost patterns, etc., are all helpful guides to understanding cartridge performance as well as wear on
cartridge components. If, for example, you use ASTM standards and only run the cartridge to 1,000 pages
then the majority of component failures will not be given sufficient time to develop. This is especially true
for the higher yield cartridges. Basing a stated page yield and page cost a “glimpse” of the cartridge’s life
