If you're looking to improve the productivity and lower the operating costs of your business, the B411/B431 Series offers all of that and more.

For starters, select series models deliver up to 40 ppm, with the first page printing in less than 5 seconds.1 They produce output in black & white that's clear and crisp, at up to 1200 x 1200 dpi resolution 2, using a two-piece consumables system for long-lasting performance and a low cost of operation.

Energy-efficient printing - All B411/B431 Series printers come with duplex (2-sided) printing standard, leading to fewer user interventions and savings on energy and media costs.

All four models have a standard paper capacity of 250 sheets and can be outfitted with an optional 530-sheet 2nd paper tray. With its 100-sheet multi-purpose tray, the B431d/dn has a maximum capacity of 880 sheets, for even longer uninterrupted productivity.

In terms of durability and reliability, B411/B431 Series printers are tough- with a monthly duty cycle rated at up to 80,000 pages.

Fit for any work environment - B411/B431 Series printers, with their compact size, fit just about any work space.

All have PCL 5e and PCL 6 emulation, and the B431 Series has PostScript 3 - emulation standard. They all perform equally well with the most popular Windows operating systems and Mac OS 10.3 and higher.

B411/B431 Series printers offer USB and parallel interfaces. Equipped with an OkiLAN internal print server, the B411dn and B431dn models make network printing more affordable- which translates into a much lower cost per user, a vital consideration as your office network grows and expands in functionality.

Backed by unmatched support - OKI Printing Solutions is so confident in the reliability and performance of the B411/B431 Series that we provide an industry-leading 5-year printhead warranty and a 1-year printer warranty with Overnight Exchange.4
