C5850N
The Okidata C5850N is a networked color laser printer from OKI's C5800 generation, built for offices with steady color volume. The cartridges stocked for it on this page are the 43865720 black, the 43865719 cyan, the 43865718 magenta and the 43865717 yellow — four separate cartridges, each replaced on its own as it runs out. Match the number on the cartridge you remove before ordering, because that number, not the printer badge, decides what fits.
A networked machine rarely belongs to one person. The C5850N typically sits where a whole team can reach it, which means its four colors drain at uneven rates: black goes first on reports and invoices, while a single busy week of charts or handouts can empty one color long before the others. Per-color replacement suits that pattern — you restock the slot that is actually empty instead of retiring a combined cartridge with toner still inside it.

Which cartridge should you buy?
For a shared office printer, the practical choice is between single cartridges and a four-color set. Singles win when one slot empties at a time, which is the normal rhythm on a networked machine — order the color the panel names and leave the rest in place. A set earns its shelf space when several colors are running low together, or when you would rather hold one complete spare set for a printer the office depends on daily. Either way, keep at least the black on hand: text work stops the moment it empties, while a missing color only blocks color jobs.
Chip, toner and everyday use
Each compatible cartridge here carries the chip the C5850N expects, so the panel reads the new cartridge and reports its level without any reset step at the machine. Seat the cartridge firmly until it locks; a cartridge resting slightly high is the usual reason a printer complains about one it has just been given. Toner yields are estimates figured at roughly five percent page coverage, so a month of dense graphics will always beat the estimate down. Store spares upright in their sealed bags, away from heat and damp, and give a cartridge that has sat for months a gentle side-to-side rock before fitting it so the toner inside settles evenly.
Frequently Asked Questions
Which toner cartridges does the C5850N take?
It takes four individual cartridges: black 43865720, cyan 43865719, magenta 43865718 and yellow 43865717. The four are not interchangeable — each color only fits its own slot — so order by the number printed on the cartridge you are replacing.
Some listings pair this printer with 43865721–43865724. Are those the same cartridges?
They are a different numbering series, and they are not what is stocked on this page. The cartridges sold here are the 43865717–43865720 series listed above. If the cartridge that comes out of your machine carries a 43865721-series number, compare carefully before ordering — the number on the old cartridge is the one that has to match.
One color has run out. Can the C5850N keep printing in black?
For plain text work, set the driver to grayscale or monochrome and the machine draws only on the black cartridge. Color documents will still need the missing color replaced, so treat grayscale as a way to keep everyday paperwork moving while the replacement ships, not as a permanent setting.
Do these compatible cartridges carry a warranty?
Yes. Compatible cartridges from Clever Supplies are covered by a one-year warranty and one-year returns, so a cartridge that fails early can be sent back rather than written off.
More printers that use the same cartridges
The same four cartridges also feed the other C5800-generation and MC560 machines below, so toner stocked for the C5850N carries across any of them you run.
