Engineered to last
A steel frame, long-life imaging system and robust paper feeding system that reliably handles diverse media types and sizes all support lasting performance in any environment.

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. That’s why Keypoint Intelligence – Buyers Lab honored Lexmark with a prestigious BLI PaceSetter award for Document Imaging Security. And this Lexmark product enables you to be GDPR ready.

Colour that only looks expensive
Thanks to PANTONE® calibration, embedded colour sample pages and Lexmark colour Replacement, you’ll get accurate, professional colour in-house. And you’ll save toner with included tools that let you choose when and how much colour to print, including mono-only print drivers, user-based colour print permissions, global colour density control, object-specific colour Saver, proof before printing and more.

Interact with ease
With its small footprint, it’s easy to find a place for. And the new front-panel power button and direct-print USB port, 2.4-inch colour LCD with keypad and secure browser-based device management make it easy to interact with.

Energy efficiency
Make every watt count with energy management features that reduce power consumption whether the device is active or in sleep mode. Lower fusing temperature, automatic management of processor cores based on workload, and standard two-sided printing all help it achieve EPEAT® Silver rating and ENERGY STAR® (2.0) certification. That benefits the planet and your budget.

Classic connections, wireless convenience
Beyond included USB and gigabit ethernet, this device lets you connect wirelessly via AirPrint, Google Cloud Print, and Mopria on any network with existing Wi-Fi access. An optional Wi-Fi card offers an additional secure, direct mobile print connection. And with Lexmark Mobile Print, printing’s as easy as hitting print, choosing your printer and picking up your job.
