Frequently Asked Questions
How long will 3,500 pages actually last in our B440?
It depends entirely on your monthly volume. At 250 pages a month, one 43979101 cartridge covers roughly 14 months of B440 printing. At 500 pages a month it lasts about 7 months, and a busy office pushing 1,000 pages a month will go through one in around 3.5 months. The 3,500-page rating is measured at the standard 5% page coverage, so dense pages with heavy text blocks or graphics will use toner faster.
What does one printed page cost with this cartridge?
At $27.70 for a cartridge rated at 3,500 pages, the math works out to roughly 0.79 cents per page — about $7.92 for every 1,000 pages your B440 prints. That is the toner cost only; paper and the printer itself are separate, but toner is usually the biggest running cost on a mono laser, and under a cent a page keeps it predictable.
How do I know the cartridge in my B440 is really running out?
The classic signs are prints that come out lighter than they used to, faded patches down one side of the page, or text that looks gray instead of black. Before you swap the cartridge, take it out and rock it gently side to side a few times — that redistributes the remaining toner and often buys you a few dozen more clean pages while the replacement is on its way.
Is the 43979101 the only number I need when reordering?
Yes — 43979101 is the Okidata part number this cartridge is built to match, and it is printed on the box and the cartridge label. If you reorder by that number, you will always get the same cartridge for your B440 without having to remember anything else about the listing.
What protection do I get if the cartridge has a problem?
Every cartridge we sell is covered by a 1-year warranty, and returns are free for a full year as well — if it fails early, leaks, or simply does not perform, you can send it back without paying return costs. Details are on our shipping and returns page. Support is available Monday to Friday, 9 AM to 5 PM CST.
Where will my order ship from?
We ship from four warehouses — Illinois, Pennsylvania, Georgia and California — and your B440 cartridge leaves from whichever location gets it to you fastest. Keeping stock in several regions means most orders spend less time in transit than a single-warehouse shipment would.
