Genuine OEM Lexmark MS312 DN Toners
The Lexmark MS312dn relies on 50F black toner, but its imaging unit, fuser, and redrive assembly are separate maintenance components. These parts solve different needs and are not interchangeable with the toner cartridge.
Toner Buzz carries genuine Lexmark 50F toner and imaging units for the MS312dn, together with fuser and redrive parts. A low-toner notice calls for toner; a named service component calls for that specific maintenance item.
