C3400N

The Okidata C3400N is a networked color printer aimed at small offices that need shared color without a large footprint. It runs on four separate cartridges — black 43459401, cyan 43459402, magenta 43459403 and yellow 43459404 — and for offices that go through yellow quickly, this page stocks the high-yield yellow cartridge 43459301.

Sharing a color printer changes which cartridge matters. On a personal machine you replace what you use; on an office machine you replace what everyone uses — and presentation decks, charts and branded documents make that a predictable pattern. The C3400N's supply plan is simply to watch the pattern and cover the colors the office actually burns.

Toner Cartridges for C3400N

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

Which cartridge should you buy?

Everyone on the network shares the same four cartridges, so buy for the office's aggregate volume rather than any one desk's habits. Standard cartridges suit steady, light color use. Where yellow runs out first — the usual story when charts and logos fill the queue — the high-yield 43459301 cuts the swap frequency on that color, and a higher-yield black, 43459304, is also made for this family for text-heavy offices. Replace each color on its own schedule; a shared machine never needs all four changed together. Keep one spare of the fastest-moving color beside the printer.

Chip, toner and everyday use

Each workstation printing to the C3400N reads the same supply levels, and an administrator can check them remotely — use that visibility, and reorder when a color first reports low rather than when a colleague's job fails. Cartridges report through a small chip, so seat each one fully when it is fitted. Remember that yield ratings assume about 5% coverage; a week of full-color presentations consumes color toner at several times the text-page rate, which is why shared color machines seem to empty "suddenly".

Frequently Asked Questions

What toner cartridges fit the Oki C3400N?

Black 43459401, cyan 43459402, magenta 43459403 and yellow 43459404 — the same set as the non-networked model. The high-yield yellow 43459301 also fits and is the cartridge sold on this page. The "N" denotes the built-in network connection.

How do I share the C3400N on an office network?

Connect the printer by Ethernet and install the driver on each workstation, pointing it at the printer's network address. The built-in network interface handles the queue from there, and everyone shares the same four-cartridge toner supply.

The C3400N prints black text with a reddish tint — what is happening?

A reddish or brown tint on "black" text means the driver is building composite black by mixing the color toners instead of using the black cartridge alone. Switch the driver to black-only mode for text documents — output turns sharper and the color cartridges stop draining on monochrome pages.

Is the high-yield yellow worth it on a shared printer?

Usually, yes. Shared color volume concentrates in charts, logos and highlighted documents, which all lean on yellow. The high-yield cartridge lowers the per-page cost on that color and means fewer mid-week changeovers for the whole office.
