Genuine OEM Lexmark T640 dtn Toners

The T640dtn uses Lexmark 640 black toner in standard and high-yield capacities. Choose between them based on cartridge-change frequency rather than treating every 640-series number as the same size.

Toner Buzz carries genuine Lexmark 640 toner for the T640dtn, plus fuser and roller supplies for maintenance. Check the printer's alert first so you select toner only for a toner message.
