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.

Interact with ease

Take command of printing, copying, faxing, and automatic two-sided scanning with a 2.8-inch (7.2 cm) color touch screen. It not only supports convenient interaction with essential system functions and task information, but includes built-in cloud connectors to help you save scans to and retrieve files from popular cloud services Box, DropBox, Google Drive, and Microsoft OneDrive.

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).
