4-in-1 Monochrome Laser for Small Offices

The Lexmark MX331ADN combines print, copy, scan and fax in one desktop unit. It produces monochrome output at up to 40 ppm with a 6.2-second first-page time. A 50,000-page monthly duty cycle supports regular department workloads. Standard 512 MB memory handles multi-page jobs without slowing the queue.

USB and Ethernet Setup with Driver Selection

Connect by USB or 10/100BaseTX Ethernet using the RJ-45 port. Install the PCL 6 or PostScript 3 emulation driver that matches your operating system; using the wrong emulation can cause garbled text or missing pages. The 350-sheet standard tray loads from the front, so allow clearance in front of the device. Duplex printing is built in and requires no extra hardware.

Check Network Ports and Paper Sizes Before Ordering

Verify your router or switch has an available 10/100 Ethernet port if you plan wired networking. The scanner bed accepts documents up to 8.5 by 14 inches; larger originals must be fed through the ADF or copied in sections. Fax operates at 33.6 Kbps over an analogue phone line, so a digital PBX extension will not work without an adapter. Media support covers plain paper, labels, card stock and envelopes up to the stated capacities.
