Impressive print speeds
The B431 races through large jobs in minimal time. The first page prints out in less than 4.5 seconds and the rest at an impressive 38 pages per minute. It’s all thanks to a powerful 330MHz processor and 64MB memory (expandable to 320MB) for faster throughput.
Use it all day, every day
True 1200 x 1200dpi resolution means that all of your everyday office documents are printed with fine, crisp detail. An extra paper supply can be added, increasing the capacity right the way up to 880 – ideal for busy offices – and there’s a 100-sheet multi-purpose paper tray for feeding a variety of different paper types and sizes.
Compact and efficient
We designed the B431 specifically to meet the demands of today’s modern offices. It’s unusually compact, so it will fit in anywhere. Its high yield consumables last as long as 10,000 pages, so you can print more, for longer. And because the toner cartridge and drum are separate units, you only ever have to replace what needs replacing so there’s no waste.
Extra value
Other essential features include automatic two-sided printing as standard, a backlit 2-line LCD display that tells you all about the current operating status of your printer and a ‘Power Save’ mode that reduces energy consumption to a frugal 8W.
Built for endurance
The B431 uses ultra-reliable digital LED technology (pioneered by OKI and proven over more than 20 years) with fewer moving parts for exceptional durability. This robust, built-to-last design means that we are confident enough to give you our industry-leading three-year warranty at no extra cost.
