Full-spectrum security
Lexmark's comprehensive approach to product security is a design and engineering mandate across our entire product portfolio. Our security features help to keep your information safe - in the document, on the device, over the network and at all points in between.

Hands-off durability
With its steel frame and lifetime fuser, the MS431dn is built to last.

Save paper, save energy
Automatic two-sided printing is standard, along with built-in energy-saving modes that help to support ratings of EPEAT® Silver and ENERGY STAR® certified. The Lexmark Cartridge Collection Programme (LCCP) and Lexmark Equipment Collection Programme (LECP) minimise waste and support recycling (availability varies by country).

Output that fits
Measuring just 222 mm high x 368 mm wide x 366 mm deep, the business-class MS431dn fits almost anywhere. Its compact size and light weight make it easy to set up and easy to move.,
