Okidata C5800 Toner | Compatible 43381904 Cartridges

C5800

The Okidata C5800 is a color laser printer from OKI's midrange office line, built for small businesses that want professional-looking color documents produced in house. It belongs to the Type C8 cartridge family: the standard set runs black 43381901, cyan 43381902, magenta 43381903 and yellow 43381904, while the high-yield line sold on this page steps up to 43324404 black, 43324403 cyan, 43324402 magenta and 43324401 yellow. Both lines fit the same four slots, so the choice between them is about how often you want to open the printer, not about compatibility.

What the C5800 sells to a small office is credibility on paper: proposals, reports and handouts with clean color that look like they came from a print shop. Compatible cartridges protect that output while pulling the running cost down, and the high-yield versions suit teams whose color printing is a daily habit rather than an occasional event. Because each color lives in its own cartridge, a heavy week of charts drains one slot at a time instead of forcing a full set change.

Which cartridge should you buy?

Start with how the printer actually gets used. The standard Type C8 set (43381901 through 43381904) covers light, occasional color work, and its lower capacity is no handicap when the machine sits idle between jobs. The high-yield line listed here earns its place when color goes out the door every day: fewer swaps, fewer interruptions mid-run, and a lower cost per page over the cartridge's life. Most C5800 owners replace colors one at a time as each runs dry — black usually first on document-heavy work — and reserve a full four-color set for the moment several cartridges run low together or the machine is being set up fresh. If you are stocking a shelf rather than solving today's empty slot, one spare black high-yield cartridge is the single most useful item to have on hand.

Chip, toner and everyday use

Each Type C8 cartridge carries a chip the C5800 reads to report toner levels, and a compatible cartridge should register cleanly the moment it is seated — push it home until it sits flat and the printer returns to ready. Page yields are estimates worked out at roughly 5% coverage, so a month of full-color brochures will empty a cartridge far sooner than the same page count of letters. When prints start to fade in one color, take that cartridge out and rock it gently from side to side; redistributing the toner inside often restores even coverage for a while. Keep unopened spares in their sealed packaging, stored flat and away from heat, and the toner stays ready whenever a slot runs dry.

Frequently Asked Questions

Which toner cartridges does the Oki C5800 take?

Two Type C8 lines fit. The standard set is black 43381901, cyan 43381902, magenta 43381903 and yellow 43381904; the high-yield set is black 43324404, cyan 43324403, magenta 43324402 and yellow 43324401. Use these exact numbers — other OKI color families are keyed differently and will not fit this model.

My C5800 prints carry a yellow cast. What is wrong?

A cast over everything usually points to one color cartridge running low or to the printer's color calibration drifting. Check the level of each cartridge first, replace any that are depleted, and then run the calibration routine from the menu so the four colors realign before you judge the next print.

Can I mix standard and high-yield cartridges in the same C5800?

Yes. Each color slot works independently, so a high-yield black can sit alongside standard colors, or the other way around. Replace whichever cartridge has emptied in whichever line suits your volume; the printer does not require all four slots to come from the same line.

Is a spare cartridge worth keeping for this printer?

For an office that prints daily, yes — a spare black prevents the dead stop that comes when the most-used cartridge empties mid-job. Black depletes fastest on mixed document work, so that is the slot to cover first. Store the spare sealed, flat and away from heat.
