High-volume monochrome LED printer

The Oki Data B731dn is a network-ready laser printer built for office workgroups that need fast monochrome output. It produces up to 55 ppm with a 5 second first print-out time and automatic duplex printing up to 42 ipm. A USB host port allows walk-up printing without a PC connection. Standard memory is 256MB and can be upgraded to 768MB.

Paper capacity and media compatibility

The standard paper capacity can be expanded to 3,160 sheets using optional trays. Maximum print size is 8.5 x 14 inches and minimum is 3 x 5 inches, with support for envelopes. Print resolution is 1200 x 1200 dpi. The printer uses wired connectivity only and is ENERGY STAR compliant. High-capacity toner cartridges rated for approximately 25,000 pages and extra-high-capacity cartridges rated for approximately 36,000 pages are available.

Sustained throughput with duplex and expansion

Under continuous load the printer maintains duplex speeds of 42 ipm while optional trays keep the paper supply large enough for long runs. The 256MB standard memory handles typical office jobs, and the 768MB upgrade option provides more buffer for complex graphics or multiple queued documents. High-capacity toner cartridges reduce the frequency of replacements during heavy daily use.

Questions about this item

What comes in the box with the B731dn and what must be purchased separately?

The printer ships as a monochrome LED unit with 256 MB standard memory, wired connectivity and a USB host port; optional paper trays to reach 3,160-sheet capacity and high-capacity (~25,000 pages) or extra-high-capacity (~36,000 pages) toner cartridges are sold separately.

Which toner capacity should I choose for the B731dn?

Choose the ~25,000-page high-capacity cartridge for typical workgroup volumes or the ~36,000-page extra-high-capacity cartridge for heavier continuous printing; both are designed for this model.

What does the 55 ppm print speed mean in daily office use?

The engine delivers up to 55 monochrome pages per minute with a 5-second first-print-out time and automatic duplex printing at up to 42 ipm, so large jobs finish quickly and double-sided output is handled without manual intervention.
