Lexmark's remanufactured Optra S print cartridge is manufactured with the same process as our new cartridges and uses genuine Lexmark toner and parts. The remanufactured Optra S print cartridge meets the original equipment specifications for yield and text print quality. We recommend that you use the remanufactured print cartridge for text only or what we term "non-critical" printing applications. When optimum printing performance is required, we suggest that you continue to use an all-new Lexmark print cartridge.
