Genuine OEM Lexmark MX812 DFE Toners
The Lexmark MX812dfe uses a 62D black toner cartridge, but the 52D imaging unit and fuser are separate supplies. Roller assemblies are maintenance parts as well, not alternate toner choices.
Toner Buzz carries genuine Lexmark 62D toner and 52D imaging units for the MX812dfe, along with fuser, transfer-roller, and pick-roller components. Match the product type to the printer's notice so a maintenance alert is not mistaken for a toner request.
