Frequently Asked Questions

Why is this drum unit sold under the number 43979001 instead of a printer name?

Because that number is how Oki identifies the drum itself. Several machines — the MB460, MB470 and MB480 MFP on the multifunction side, and the Oki B410, B410dn, B420dn and B430d printers — all take this same drum unit, so the part number 43979001 is a more precise label than any single model name. If the drum coming out of your machine is marked 43979001, this is its replacement.

What does a drum unit actually do — isn't printing the toner's job?

They split the work. The toner cartridge supplies the black powder; the drum unit is the imaging surface that picks that powder up and transfers the page image onto the paper. That is why a printer can have plenty of toner left and still print badly: the imaging surface wears with every revolution, and once it is tired the defects show up on every page.

How long should one 43979001 drum last?

It is rated at up to 25,000 pages. In practice that means a drum change is a rare event compared with toner changes — a small office may go well over a year on one drum, while a busy department printing thousands of pages a month will work through the rating faster. The rating counts pages imaged, so heavy daily volume is what consumes it.

How do I tell a worn drum from an empty toner cartridge?

Look at the pattern of the defect. Toner running low fades evenly and improves, at least briefly, when you rock the cartridge. A worn drum leaves its signature in the same place on page after page: repeating spots or marks at regular intervals, a gray haze in areas that should be white, or streaks that survive a brand-new toner cartridge. Defects that repeat at fixed spacing are the drum telling you its surface is done.

Is this a genuine Oki drum unit?

No — it is a compatible drum unit built to the 43979001 specification, sold under the Clever Supplies name rather than Oki's. It is covered by a one-year warranty and one-year free returns, with the full terms set out on the shipping & returns page.

Where will my drum ship from, and who helps if I have a question?

Orders leave from one of four warehouses — IL, PA, GA or CA — whichever puts it closest to you. Questions are answered by a real support team Monday through Friday, 9 AM to 5 PM CST, and the wider range of drums and toner for these machines is gathered on the Okidata brand page.

About This Drum Unit (43979001)

This is the number-first way to replace the imaging drum in the Oki B410 family and the MB460–MB480 multifunction machines: one compatible black drum unit, part number 43979001, rated at up to 25,000 pages and priced at $63.18 — roughly a quarter of a cent per page of drum life. Because the drum forms the image itself, replacing a worn one is what clears repeating spots, background haze and streaks that new toner cannot fix. It is backed by a one-year warranty and one-year free returns.
