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 keep your information safe—in the document, on the device, over the network, and at all points in between.
Connectivity central
In addition to Ethernet and USB, built-in Wi-Fi makes it easy for mobile users to get output via the Lexmark Mobile Print app, as well as Mopria®, AirPrint and Google Cloud Print. And the Lexmark Mobile Assistant app simplifies wireless configuration.
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).
Versatility that fits
Measuring just 13.3 inches high x 16.2 inches wide x 14.4 inches deep (339 mm high x 411 mm wide x 366 mm deep), the business-class MX431adw fits almost anywhere. Its compact size and light weight make it easy to set up and easy to move.
Interact with ease
Take command of printing, copying, faxing, and automatic two-sided scanning with a 2.8-inch (7.2 cm) color touch screen. It not only supports convenient interaction with essential system functions and task information, but includes built-in cloud connectors to help you save scans to and retrieve files from popular cloud services Box, DropBox, Google Drive, and Microsoft OneDrive.
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 20,000 pages** of output, while an optional paper tray increases total input capacity up to 900 sheets for more printing and less downtime. And with its steel frame and lifetime fuser, the MX431adw is built to last.
