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 MS331dn 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 MS331dn fits almost anywhere. Its compact size and light weight make it easy to set up and easy to move.

Print more, stop less
Optional High Yield Unison toner provides up to 15,000 pages of output, whilst an optional paper tray increases total input capacity by up to 900 sheets for more printing and less downtime.
