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 MX331adn fits almost anywhere. Its compact size and light weight make it easy to set up and easy to move.

Print more, stop less
Available High Yield Unison™ toner provides up to 15, 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 MX331adn is built to last.

Solid performance, flexible connectivity
Power through challenging jobs with output up to 40 pages per minute* and automatic single-sided scanning at up to 48 images per minute. Connect via USB or Ethernet to give your whole team access.

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.

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.

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).
