Description

Ready when you are
Robust and reliable, Lexmark printers 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.

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.

Performance and value
Get mono printing at up to 40 pages per minute, plus standard two-sided printing, at an affordable price. Durability and long-life components keep your maintenance costs low, too.

Energy efficiency
Make every watt count with energy management features that reduce power consumption, whether the printer is 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.

The definition of clear text
Some laser printers struggle to print grey text that’s easy to read - not the MS420 series. Its innovative font outlining technology makes even the smallest grey text crisp and clear.

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.
