Rated print speeds of up to 42 ppm*, plus fax, scan, and copy functions come together in the XM1242, powered by a 1-GHz dual-core processor, a full gigabyte of memory and two-sided automatic document feeder. There’s standard USB and Ethernet for easy connectivity and secure networking, plus available Wi-Fi. Start with the 350 sheets of standard input and expand it to up to 900. You’ll stop less for service thanks to long-life 60,000-page imaging units**** and replacement toner cartridges that print up to 21,000 pages**.


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 up to 21,000 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 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 Security3 . And this Lexmark product enables you to be GDPR ready.

Unexpected extras

  • In addition to monochrome output at up to 42 ppm, the XM1242 includes two-sided scanning and a 4.3-inch [10-cm] touch screen featuring a wide selection of standard solutions that enhance ease of use, customization and efficiency.

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 the way 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 meet rigorous ENERGY STAR 2.0 requirements. That benefits the planet and your budget.

Versatile media handling

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