Ready when you are
Robust and reliable, Lexmark multifunction products are built to work anywhere, from showroom to warehouse, with few interventions. Keep going with long-life components and replacement cartridge yields of up to 20,000 pages.

Multi-core power
A 1 GHz dual-core processor with 1 GB of standard memory gives you the power to do a combination of faxing, printing, copying and scanning for maximum productivity. And you can be confident that your complex file with images, charts and small print will look just as the way that you designed it.

Energy efficiency
Make every watt count with energy management features that reduce power consumption, whether active or in sleep mode. Lower fusing temperature and automatic management of processor cores based on workload help to meet rigorous ENERGY STAR 2.0 requirements. That benefits the planet and your budget.

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

Wireless convenience
Standard USB and gigabit ethernet are just the start. The MX321adw has standard Wi-Fi for secure and easy connectivity and an easy-to-use app, Lexmark Mobile Assistant, to allow device setup directly from your mobile device.

Versatile media handling
Print what you want, in the size that you want. The standard media tray adjusts to paper sizes from A6 to legal, whilst the 100-sheet multipurpose feeder accepts smaller media and envelopes to give you even more design and output possibilities.
