Okidata 44992405

One black cartridge covers two Okidata lines at once. The 44992405 is the laser toner for the B401 printer family and the MB451 multifunction family — eight models that share a single supply, so there is exactly one code to match and no colors to keep track of. If the cartridge that came out of your machine carries this number, you are on the right page whichever of the eight models you own.

The table below sells the cartridge under two listing names — by its part number and as the B401 cartridge — and they are the same cartridge in both. Suffixes on the printer names mark factory variants (the B401D and B401DN, the MB451W beside the MB451), and none of them changes the supply: duplex and network versions drink from the same cartridge as the base models. What you are choosing between is pack size — singles, a 3 pack and 5 packs.

Which 44992405 should you buy?

A single cartridge is the right order for one lightly used machine. Offices running several of these printers, or one MB451 that scans and prints all day, usually step up to the 3 pack or a 5 pack so a spare is always on the shelf — the cartridge is identical in every box, and the B401-named 5 pack holds the same supply as the part-number 5 pack. There is nothing else to bundle with it: this family takes no separate drum or second supply from this page. Every compatible cartridge here carries a one-year warranty, and returns run for one year as well.

Toner care for a shared office cartridge

When output fades near the end of a cartridge, remove the 44992405 and rock it gently side to side to redistribute the toner — that usually restores even pages long enough for the next cartridge to arrive. Keep spares sealed in their boxes, stored flat and out of direct heat, and fit a fresh cartridge by its housing rather than by any exposed roller or contact. Because one code serves eight models, busy offices often keep the spare where every machine's users can reach it, labeled with the part number rather than a model name — the number is the part everyone shares.

Frequently Asked Questions

Does the 44992405 fit both the MB451W and the B401DN?

Yes. The MB multifunction models and the B401 printers share this one cartridge — MB441, MB451, MB451 MFP, MB451W and MB451W MFP on one side, B401, B401D and B401DN on the other. The number on the cartridge is the whole fit check.

Is the cartridge listed as a B401 cartridge different from the 44992405?

No. They are the same compatible cartridge under two listing names — one keyed to the part number, one to the B401 model line. Pack size is the only reason to choose between the listings; the supply inside is identical.

Is there a drum or a second supply item for these printers?

Not on this page. The 44992405 is the family's only supply listing here — no separate drum code is sold for these models in this range — so a toner order is the whole order.

Which pack suits an office with two B401s and an MB451?

Start with a 5 pack. Three machines drawing on one cartridge code empty singles quickly, and the larger box keeps a spare in reach of all three; move to singles only if the machines print rarely.
