Give every small workgroup color output with the compact, lightweight Lexmark CS431dw, ready to network or share wirelessly with output at up to 26 ppm.

Classic connections, wireless convenience

In addition to Gigabit Ethernet and USB connectivity, dual-band Wi-Fi makes it fast and easy for mobile users to get output via the Lexmark Mobile Print app, as well as Google Cloud Print, Mopria®, and AirPrint technologies. And the Lexmark Mobile Assistant app simplifies wireless configuration.

Compact and durable

Compact and lightweight, the CS431dw fits almost anywhere. But its steel frame and long-life imaging components mean it's also built to last.

Color you can count on

Get rich, vibrant color in seconds with Lexmark's unique Unison™ toner. And easy-to-change Extra High Yield replacement cartridges give you more printing and less downtime.

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.

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).

Interact with ease

A 2.8-inch [7.2-cm] color touch screen enables convenient interaction with essential system functions and task information, while built-in cloud connectors let you securely access files from popular cloud services Box, DropBox, Google Drive, and Microsoft OneDrive.
