Frequently Asked Questions

Who is a three-pack of black cartridges the right size for?

An office that prints steadily all quarter and dislikes reordering. Three 43866104 cartridges give a C710dn 33,000 pages of black — enough to cover a full business quarter for many small teams without a standing order or a mid-quarter scramble when the toner light comes on.

What do I actually save by taking three at once?

The three-pack is $98.79, or $32.93 per cartridge. Three singles bought one at a time would cost $135.75, so you keep $36.96 — close to the price of a whole extra cartridge over the year if you repeat the order. The per-page cost of black falls to roughly 0.30 cents.

Are all three cartridges the same 43866104?

Yes — three identical compatible black cartridges, each rated at 11,000 pages, each made for the C710dn and C710dtn. The 43866104 is the black position of the four-cartridge 43866101–43866104 family; this pack is simply the black supply in triplicate.

Will the third cartridge still be good when I finally open it?

Yes. Kept sealed in its bag in a cool, dry place away from direct light, a toner cartridge stores comfortably for the months it takes a normal office to work through the first two. Rotate stock — use the oldest first — and there is nothing to worry about.

Does buying in a pack change the cartridge or its warranty?

No. The cartridge is the same unit sold as a single, and every one of the three is covered by our one-year warranty and one-year free returns, spelled out on the shipping & returns page.

How quickly can I get help if a cartridge misbehaves?

Our support team works Monday to Friday, 9 AM to 5 PM CST, and orders leave from our warehouses in IL, PA, GA and CA, so replacements move fast when something goes wrong.

About This 43866104 Three-Pack

Think of this listing as a quarter's worth of black for a C710dn, bought in one line item: three compatible 43866104 cartridges for $98.79, 33,000 pages in total, and a per-cartridge price of $32.93 instead of $45.25. It suits offices that would rather approve one purchase than three. The rest of the Oki range, including the color siblings of this cartridge, lives on our Okidata page.
