Save paper save energy

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

Output that fits

Measuring just 8.7 inches high x 14.5 inches wide x 14.3 inches deep (222 mm high x 368 mm wide x 363 mm deep) the business-class MS431dw fits almost anywhere. Its compact size and light weight make it easy to set up and easy to move.

Print more stop less

In addition to a first page as fast as 5.9 seconds and output up to 42 pages per minute* available Extra High Yield Unison™ toner provides up to 20000 pages of output. Add an optional paper tray that increases total input capacity up to 900 sheets for more printing and less downtime.
