C3400

The Okidata C3400 is a compact color laser printer pitched at home offices and small teams that need occasional color without a bulky machine. Its black cartridge is rated for about 1,500 pages and each color for about 1,000 pages: black 43459401, cyan 43459402, magenta 43459403 and yellow 43459404. For desks that go through yellow quickly, this page stocks the high-yield 43459301 yellow cartridge.

The C3400 earns its keep in spaces where a full departmental color machine would be overkill — a home office printing proposals, a small team sharing invoices and the odd presentation. Its supplies mirror that scale: four modest cartridges, each replaced on its own schedule, rather than one large assembly swapped all at once.

Toner Cartridges for C3400

The standard cartridges for this printer are 43459401 (black, about 1,500 pages), 43459402 (cyan), 43459403 (magenta) and 43459404 (yellow, about 1,000 pages each for the colors). The listing above is the high-yield yellow option sold for this family.

Which cartridge should you buy?

With yields this size, the buying question is mostly about rhythm. If the printer handles a few pages a day, standard cartridges are the sensible default and each color is changed only when it actually empties. Busier desks should look at where the pages go: color documents drain yellow fastest when logos and charts dominate, and the high-yield 43459301 answers exactly that pattern with fewer swaps per thousand pages. High-yield versions of the family exist for heavier periods as well. Whichever mix you choose, replace colors individually — there is no benefit in retiring a half-full cartridge early.

Chip, toner and everyday use

Each cartridge carries a chip the printer reads for level reporting, so push every cartridge home until it locks; a loose cartridge reads as missing. This design keeps the toner and the image drums separate, which is kind to running costs — a worn drum never forces you to discard good toner. Remember that the stated yields assume roughly 5% coverage: a page of full-color charts can use several times the toner of a text page. Keep spares in their sealed packaging, stored flat and out of sunlight.

Frequently Asked Questions

Which toner does the Oki C3400 use?

Black 43459401 (about 1,500 pages), cyan 43459402, magenta 43459403 and yellow 43459404 (about 1,000 pages each). The high-yield yellow 43459301 also fits and is the cartridge sold on this page. The printer shares this toner family with the C3300 and C3400N models.

Is the C3400 still worth running, given its age?

If it prints cleanly, yes — the cartridge family is still available from compatible suppliers, and the separate toner-and-drum design keeps running costs low. The realistic age concern is driver support on the newest operating systems, so confirm your computer can drive it before relying on the machine for daily work.

What causes horizontal bands across C3400 color prints?

Evenly spaced horizontal bands usually point to a worn image drum, not the toner — each drum repeats its defect at the same interval. Bands in a single color implicate that color's drum; bands across every color suggest the transfer belt is due for replacement.

Should I choose the high-yield yellow or the standard?

Choose the high-yield 43459301 if yellow is the cartridge you replace most — it lowers cost per page and stretches the interval between changes. If color printing is occasional, the standard yellow keeps less money sitting in a cartridge.
