Versatility that fits
Measuring just 339 mm high x 411 mm wide x 366 mm deep, the business-class MX431adn 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 of up to 40 pages per minute*, optional Extra High Yield Unison™ toner provides up to 20, 000 pages** of output, whilst an optional paper tray increases total input capacity by up to 900 sheets for more printing and less downtime. And with its steel frame and lifetime fuser, the MX431adn is built to last.

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.

Interact with ease
Take command of printing, copying, faxing and automatic two-sided scanning with a 7.2 cm colour touch screen. It not only supports convenient interaction with essential system functions and task information, it also includes built-in cloud connectors to help you to save scans to and retrieve files from popular cloud services Box, DropBox, Google Drive, and Microsoft OneDrive.

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).
