Light, compact and fast, the MS331dn supports output of up to 38 pages per minute, multiple connectivity options and an optional 550-sheet paper tray. 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. With its steel frame and lifetime fuser, the MS331dn is built to last. 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).
