The toner cartridges included in Lexmark's return program are printing toners that are sold at a reduced price, in exchange for the customer accepting the condition that the cartridges will be used only once and returned only to Lexmark for remanufacturing or recycling. These single-use toners cease to function when they reach the end of their rated life, as determined by Lexmark (there may be a variable amount of toner remaining in the cartridges when replacement is required). These toners can also automatically update the printer's memory to protect it from counterfeit and unauthorized products.
