Compact mono laser for small workgroups

The Lexmark MS431dn is a new monochrome laser printer built for small workgroups that need fast, reliable output. It prints up to 42 ppm with a first page out in 5.9 seconds and a maximum duty cycle of 80,000 pages per month. A 256 MB memory and 1 GHz dual-core processor handle the print queue.

Fits tight spaces and grows with paper needs

At 8.7 inches high by 14.5 inches wide by 14.3 inches deep the unit sits on a desk or shelf without dominating the area. Standard input holds 350 sheets across two trays and an optional 550-sheet tray raises total capacity to 900 sheets. Duplex printing is built in and the 150-sheet output bin keeps pages stacked neatly.

Steady throughput on long print runs

The 2400 IQ engine delivers 2400 x 600 dpi quality without slowing down during extended jobs. Gigabit Ethernet plus USB give the whole team wired access and the printer supports PCL 5c, PCL 5e, PCL 6, PostScript 3 and Direct Image languages. Extra High Yield Unison toner cartridges yield up to 20,000 pages so toner changes stay infrequent.

How much noise and heat does it produce when running continuously at 42 ppm?

With a 1 GHz dual-core processor and 256 MB memory driving speeds up to 42 ppm, the MS431dn is built for steady, business-class operation throughout the day.
