Genuine OEM Lexmark T642 n Toners

Lexmark 640 black toner for the T642n comes in standard and high-yield capacities. Standard is the simpler choice for lighter use, while high yield gives busier printers more toner between cartridge changes.

Toner Buzz carries genuine Lexmark 640 toner, fuser units, and roller parts for this model. Start with the message on the printer: a low-toner notice calls for toner, while a named fuser or roller alert points to maintenance.
