Genuine Lexmark supplies are engineered to work Best Together with your Lexmark printer, delivering excellent print quality from the first page to the last.

These cartridges may also automatically update the printer memory to protect the printer from counterfeit and unauthorized products. Maximize your savings and enjoy premium quality with Genuine Lexmark cartridges. High Yield cartridges offer a lower cost per page and contain more pages than Standard Yield cartridges do.
