Okidata C5950 Toner | Compatible 43865724 Cartridges

C5950

The Okidata C5950 is a color printer built for office color workloads. The cartridges stocked on this page are the high-yield Type C8 line, sold here under C5500 listings: black 43324404, cyan 43324403, magenta 43324402 and yellow 43324401. Before reordering, check the part number on the cartridge installed in your machine and match it to the listings below — that number, not the printer name on the box, is what guarantees the right fit.

A color machine that spends months printing black-only documents can surprise its owner: the color toner settles, the printer runs cleaning cycles while the colors sit idle, and the first big color job afterwards comes out shifted. A short color test page once a week keeps the three color cartridges flowing and the output honest.

Which cartridge should you buy?

Everything stocked here is the high-yield line, which suits a machine bought for steady color work: fewer swaps, and a lower cost per page than standard-capacity cartridges. Black is offered singly and in two-, three- and five-cartridge multipacks for text-heavy offices, while the colors can be bought one at a time or in three- and six-color sets when several run low together. Replace only the slot that is empty; there is no economy in retiring a half-full color cartridge because its neighbor ran out.

Chip, toner and everyday use

Run the printer’s calibration routine before an important color job, especially after a long run of black-only work — it realigns the four colors so they register cleanly on the page. Each cartridge is chipped and reports its own level, and a cartridge the machine fails to read usually just needs to be lifted out and pressed firmly back into its slot. Keep unopened spares in their packaging, flat and out of direct sunlight, and fit them only when the printer calls for them.

Frequently Asked Questions

Which toner cartridges fit the OKI C5950?

This page stocks the high-yield Type C8 cartridges under C5500 listings: black 43324404, cyan 43324403, magenta 43324402 and yellow 43324401. Verify the number on the cartridge you remove before ordering, and order the listing that carries that number.

The colors on my C5950 shifted after months of black-only printing. Why?

Color toner settles when it sits, and the printer spends small amounts on cleaning cycles while the colors are idle. Print a color test page weekly to keep the color cartridges flowing, and run calibration before important color work.

Are the cartridges on this page genuine OKI products?

They are compatible replacements built to the Type C8 part numbers shown, covered by a 1-year warranty with 1-year returns.

Should I replace all four cartridges when one runs out?

No. The four slots are independent — replace the empty color and leave the others until they report low. Sets are for restocking several low cartridges at once, or for shelf spares.
