Frequently Asked Questions

When is the right moment to order a replacement for an MB451?

When the prints start to fade or the machine reports low toner — not after it stops. This compatible 44992405 cartridge is rated at up to 1,500 pages and costs $36.57, and a spare ordered at the first warning reaches you from our IL, PA, GA or CA warehouses before the old cartridge gives out entirely.

Which cartridge does the MB451 use?

The 44992405 black cartridge — the same unit that feeds the MB441 and the B401, B401D and B401DN printers. This listing is the compatible version of that cartridge. If the label on your spent cartridge reads 44992405, you have found its replacement.

My MB451's copies look gray instead of black — is it the cartridge?

Usually, yes. Gray, washed-out copies are the classic sign of a cartridge at the end of its toner. A gentle rock of the cartridge side to side can revive it briefly, but full-density copies need a fresh cartridge. If a new cartridge still copies gray, the issue is in the machine, not the toner — and your cartridge is covered by a one-year warranty either way.

What does printing cost with this cartridge?

About 2.44 cents per page as a single ($36.57 for up to 1,500 pages). The 5-pack of the same cartridge in this family brings that to roughly 1.45 cents if your MB451 works hard enough to justify bulk.

Is this an Oki original?

No, it is a compatible cartridge sold under the Clever Supplies brand, covered by a one-year warranty and one-year free returns — see our shipping and returns policy for how that works. Support is available Monday to Friday, 9 AM to 5 PM CST.

Should I keep a spare for the MB451?

If the machine handles daily office work, yes — a multifunction that cannot print also cannot copy, so a spare on the shelf is cheap insurance. The 3-pack and 5-pack sizes of this cartridge are listed with the rest of the family in our Okidata range.
