Frequently Asked Questions
What exactly arrives when I order this C710dn cartridge?
One compatible black toner cartridge, part number 43866104, sealed and ready to install in an Oki C710dn or C710dtn. It is rated at 11,000 pages and priced at $45.25. Nothing else is in the box — this listing restocks the black position only.
My black is empty but the colors still have toner — can I change just this one?
Yes, and that is the normal pattern with this machine. The four cartridges — 43866101, 43866102, 43866103 and this 43866104 black — are independent, and black almost always runs out first because documents are mostly black text. Swap the black, leave the colors in place, and keep printing.
How many pages should I realistically get from it?
The 11,000-page rating comes from the standard 5% coverage test. Everyday office documents land close to that figure, so at $45.25 your black costs roughly 0.41 cents a page. Dense pages with heavy graphics will use toner faster; light text memos will stretch it further.
Is this an original Oki cartridge or a compatible one?
It is a compatible cartridge manufactured to the 43866104 specification, not an Oki-branded unit. It fits the same slot in the C710dn and carries our one-year warranty and one-year free returns instead of the original manufacturer's cover.
What should the first prints look like after I install it?
Clean and even from the first page. Run a test sheet or two: text should be solid black with no streaks, fading or background shading. If anything looks off, reseat the cartridge once — and if it still is not right, contact us while the warranty terms on our shipping & returns page apply.
How fast will it reach me, and who do I call with a problem?
Orders ship from our warehouses in IL, PA, GA and CA, so most customers are a short transit away. Our support team is available Monday to Friday, 9 AM to 5 PM CST if you need help choosing or troubleshooting.
