Introduction

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.

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).

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.

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 CX431adw fits almost anywhere. But its steel frame and long-life imaging components mean that it’s also built to last.

Colour you can count on
Get rich, vibrant colour in seconds with Lexmark’s unique Unison™ toner. And easy-to-change Extra High Yield replacement cartridges give you more printing and less downtime.
