Is the Lexmark MX431ADN worth it for a small office?

If you mostly print black-and-white documents and need scanning, copying and faxing in one machine, it covers all of that at 42 ppm with duplex printing. At $474.00 at Adorama as of November 7, 2026, it is priced like a workgroup machine, so it makes most sense if you will use the ADF and network features.

Does it print in color?

No. It is a monochrome laser printer, so all output is black and white.

Can it scan and copy double-sided documents?

Yes. It has an automatic document feeder and automatic duplex printing, so it can scan and copy two-sided originals without manual flipping.

What paper sizes does it support?

It handles A4, Letter, Legal, A5 and A6, which covers standard office documents and smaller media.

It connects over Ethernet or USB and supports AirPrint for printing from Apple devices. There is no Wi-Fi listed, so plan on a wired network connection.

What comes in the box?

Expect the printer, a starter toner cartridge, power cable and setup documentation. A full-capacity toner cartridge and any extra paper trays are sold separately.
