Built for small workgroups

The Lexmark MX331adn is a 4-in-1 monochrome laser printer that prints, copies, scans and faxes at up to 40 pages per minute. It has a 2.8 inch LCD touch panel and supports duplex printing. Standard connectivity includes USB and Ethernet 10/100BaseTX. A robust steel frame and lifetime fuser are designed for durability.

Not for high-volume colour or advanced finishing

This model only outputs black toner, so buyers who need colour documents should look elsewhere. It lacks an automatic document feeder for two-sided scanning, limiting batch digitisation. The maximum monthly duty cycle is 50,000 pages, which may not suit very large departments. Offices requiring staple, hole-punch or booklet finishing need a different device.

40 ppm mono print speed

The single figure that defines this printer is its 40 pages per minute black print speed. With a 6.2 second first-page-out time and 600 x 600 dpi resolution, it matches the pace of a busy small workgroup. If your daily volume regularly exceeds this throughput, a faster engine is required.

Questions about this item

Which network port does the MX331adn use to connect to an office LAN?

The printer has a 10/100BaseTX Ethernet port (RJ-45) for wired network access.

Can the MX331adn scan double-sided originals without manual flipping?

The scanner uses a single-sided CIS element, so two-sided pages must be fed again manually.

How can I verify the MX331adn is printing at its rated speed?

Print a multi-page job and time it; the spec states up to 40 ppm with a first page out in 6.2 seconds.
