Keeping your Lexmark machine running using the highest quality black toner powder, like that found in the genuine 0012A6839, should be a priority for every printer owner. Monochromatic laser printers like the Lexmark X522s (and all other compatible machines) rely upon precision to produce some of the sharpest prints available, and the original 12A6839 makes this possible.
With an estimated page yield of 20,000 prints, the Lexmark12A6839 black toner cartridge is a pretty substantial unit and well worth the asking price. Along with the inherent quality of the Lexmark 0012A6839 toner cartridge, you also get a full warranty with the manufacturer themselves.
