Laser toner cartridge testing

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
that disassembly prior to testing affects the integrity of the cartridge.
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
cycle cannot provide enough confiden

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 patterns using a mixture of marching text, solids,

then the majority of component failures will not be given sufficient time to develop. This is especially true
