Genuine OEM Lexmark MX511 DTE Toners
The Lexmark MX511dte uses 60F black toner with standard and high-yield choices. Imaging is handled by a separate 50F unit, and 40X8023 identifies the fuser, so those parts should not be confused with toner.
Toner Buzz carries genuine Lexmark supplies for each role. Choose toner according to the yield needed, or follow an imaging-unit or fuser message to the specific maintenance component.
