Genuine High-Yield Toner for B731dn

This genuine Oki Data cartridge is designed for the B731dn LED printer. It supplies black toner rated at 36000 pages, reducing the frequency of replacements in busy offices. The single-pack format keeps inventory simple for low-to-medium volume environments.

Extra-High Yield Lowers Cost Per Page

The extra-high yield rating of 36000 pages means fewer cartridge changes and a lower cost per printed page compared with standard cartridges. Genuine formulation protects the LED engine from leaks or inconsistent density that can arise with non-original toner. Consistent output helps maintain professional document quality over long runs.

Compatibility Limited to B731 Series

This cartridge fits only the Oki Data B731 series printers listed in the specifications. Buyers with other Oki models or non-Oki devices cannot use this part. Check the printer model label before ordering to avoid a mismatch.

Questions about this item

When will the 45439001 cartridge need replacement based on its rated yield?

The cartridge is rated for approximately 36000 pages, so replacement is needed once that volume has been printed.

What limits continuous printing on the B731dn when using this toner?

The LED print engine and toner capacity set the practical limit; the cartridge delivers up to 36000 pages before a change is required.

Does the 45439001 generate extra heat or noise during long print runs on the B731 series?

As a passive toner supply it adds no moving parts; heat and noise come from the printer's LED engine, not from the cartridge itself.
