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.
Flexible connectivity
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.
Print more, stop less
In addition to a first page as fast as 5.9 seconds and output up to 40 [38] pages per minute, available Extra High Yield Unison™ toner provides up to 20,000 pages of output. Add an optional paper tray that increases total input capacity up to 900 sheets for more printing and less downtime.
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).
