Workgroup 4-in-1 Laser Printer

The Lexmark MX431adn combines printing, copying, scanning and faxing in a single monochrome device built for shared office use. A 2.8 inch LCD touch panel provides direct access to all functions. Standard Ethernet and USB connections integrate the unit into existing network infrastructure. It is suited to teams that need a consolidated document station without colour output.

Monthly Duty Cycle 80000 Pages

The manufacturer rates the engine for up to 80000 pages per month, a figure that defines the workload ceiling for this model. Exceeding this volume on a regular basis will accelerate wear and increase service intervals. Buyers planning higher continuous throughput should evaluate hardware with a larger rated duty cycle.

Sustained Output with Duplex and High-Yield Toner

Duplex printing runs automatically at the rated 42 ppm speed, maintaining double-sided throughput without manual intervention. Extra High Yield Unison toner cartridges supply up to 20000 pages per cartridge, reducing replacement frequency during long print runs. The 512 MB standard memory buffers complex jobs to keep the engine fed during extended sessions.

Questions about this item

How many pages per minute will the MX431adn actually print once it is in my office?

The printer is rated up to 42 ppm for black output; real-world speed depends on job complexity, duplex mode and paper type.

What does the Ethernet 10/100/1000BaseTX (RJ-45) connection limit in daily use?

The Gigabit Ethernet port caps wired network throughput at 1 Gbps, which is well above typical print-job data rates.

What desk space and paper capacity does the MX431adn need to fit and run?

It measures 13.3 in high, 16.2 in wide and 14.4 in deep; standard input holds up to 900 sheets with the optional tray added.
