High-yield toner cartridges generally have the same size and shape as standard-yield cartridges, but they contain more graphite powder. This means that a high-yield toner cartridge prints more pages before needing replacement, resulting in a lower cost per page.

Toner cartridges included in Lexmark's return program are discounted printing toners, with the condition that the customer accepts that the cartridges will be used only once and returned only to Lexmark for refurbishment or recycling. These single-use toners stop functioning when they reach the end of their rated life, as determined by Lexmark (there may be a variable amount of toner remaining in the cartridge when replacement is required). These toners can also automatically update the printer's memory to protect it from counterfeit and unauthorized products.
