Lexmark X651H11A Toner, 7,000 Page-Yield, Black

Outstanding results page after page, year after year. Superior design means precision pairing between printer and cartridge for value, quality and environmental responsibility you can count on. A variable amount of toner will remain in the cartridge when replacement is required. In addition, the cartridge is designed to automatically update the memory in your printer to protect against the introduction of counterfeit and/or unauthorized third-party cartridges.
