Oki B431DN review: Oki B431DN

The appeal of the Oki B431DN lies in its simple setup and ease of use, but we wish the software came with an onscreen dashboard to show information like job progress or toner levels. Still, it's hard to complain about minor details when Oki provides other productivity features, like the internal autoduplexer that lets you save money by printing on both sides of a sheet of paper.

Performance
The Oki B431DN is by far the most efficient of the printers we compared in terms of output speed, and we're impressed by how easily it outpaced the competition. The Oki product page advertises 40 pages per minute (ppm) and our test results for all three categories are just about congruent with those claims at 38.16 ppm for the 10-page presentation test, 33.3 ppm for the graphics page, and 33.86 ppm for a simple page of black text. If raw speed is your purchasing criterion, look no further than the B431DN.

The Oki B431DN is actually an LED printer that uses a light diode instead of a laser as a printhead source, and is an economical alternative to the typical laser printer we usually see because LEDs require fewer internal parts to operate. The shorter optical path on LED printheads also allows for a smaller physical size than classic laser printers, but you sacrifice quality for convenience, as current LED printers all have fixed resolutions. That said, you won't notice a big difference in print quality, especially from a monochrome printer like this one.

We printed our usual array of test graphics and text pages and the quality will more than suffice for throwaway documents and light graphics, but you might consider a multicartridge inkjet printer or even a color laser if you want to print snapshot photos or presentation-quality documents.

Service and support
The B431ND is covered by Oki's limited warranty on parts and labor for one year, including overnight exchange in the event of a malfunction. Customer support and technical specialists are also available 24 hours a day, 7 days a week, and 365 days a year by e-mail and phone, and the comprehensive Support Resources page on the Oki Web site provides further customer assistance by way of FAQs, driver downloads, warranty extension opportunities, business document templates, order status updates, and individual resources (manuals, documents) for each printer model Oki sells.
