Long life
Thanks to its steel frame and built-in fuser unit, the MS431dn will serve you for a long time.

The entire range of security solutions
Lexmark's comprehensive approach to product safety characterizes both the design and engineering of our entire product portfolio. Our security features help protect your data—in the document, on the device, on the network, and everywhere in between.

Saves paper and electricity
Its standard equipment includes automatic two-sided printing and built-in energy-saving modes, thanks to which it received EPEAT® Silver and ENERGY STAR® certification. Lexmark Supplies Collection Program (LCCP) and Lexmark Device Collection Program (LECP) minimize waste and promote recycling (programs not available in all countries).

Performance in a small size
Designed for businesses, the MS431dn is just 222mm high, 368mm wide and 363mm deep, so it fits virtually anywhere. Thanks to its compact size and light weight, it can be easily installed and moved.

Excellent performance and flexible connection
It prints the first page in just 5.9 seconds, and with its 1 GHz dual-core processor and 256 MB memory, it can handle large tasks with ease. It can be connected via USB or Ethernet so the whole team can use it.

More printing and less waiting
First page out in just 5.9 seconds, then print at 40 pages per minute* – up to 20,000 pages** with the extra high-capacity Unison™ toner cartridge, while the optional paper tray increases total input capacity to 900 sheets, so you can print more with less downtime.
