Keeping your Lexmark T420 running using the highest quality black toner powder, like that found in the genuine 0012A7410, should be a priority for every printer owner. Monochromatic laser printers like the T420D (and all other compatible machines) rely upon precision to produce some of the sharpest prints available, and the original 12A7410 makes this possible.
With an estimated page yield of 5,000 prints, the Lexmark 0012A7410 black toner cartridge is a pretty substantial unit and well worth the asking price. Along with the inherent quality of the Lexmark 12A7410 toner cartridge, you also get a full warranty with the manufacturer themselves.
