Product Identity

The Lexmark MS631dw is a monochrome laser printer built for workgroups that need fast black-and-white output. It produces up to 50 pages per minute and supports wireless, Ethernet and USB connectivity. A buttonless touchscreen simplifies job control. The engine is rated for a toner yield of up to 31,000 pages.

Thermals Noise Power

Laser printing generates heat during warm-up and continuous runs; the MS631dw uses advanced power management to reduce energy draw between jobs. Acoustic output rises with the 50 ppm throughput but remains within typical office background levels. Power consumption scales with page volume and idle intervals.

Deciding Specification

Maximum print speed reaches 50 ppm at 1200 dpi x 1200 dpi resolution. This throughput defines whether the printer matches your peak demand. Buyers who need colour output or a lower-volume device should consider other models.

Questions about this item

How do I connect the MS631dw to my network, and what step do people skip?

Use the touchscreen to join Wi-Fi or plug in Ethernet, then install the driver on each computer; the step often missed is adding the printer by IP address instead of relying on auto-discovery.

Which supply will need replacing first on the 38S0400, and at what page count?

The toner cartridge yields up to 31,000 pages and is the first consumable to require replacement under normal use.

What limit appears first during a long print run on this 50 ppm laser printer?

The engine is rated for 50 pages per minute; sustained output will hit that speed ceiling before any other constraint.
