Frequently Asked Questions

What toner fits the Oki C5900dn?

The C5900dn uses black 43381901, cyan 43381902, magenta 43381903 and yellow 43381904 — identical to every other C5900 variant.

Is the C5900dn the same printer as the C5900dtn?

Nearly — both use the same 43381901–43381904 toner cartridges and the same print engine. The “t” in cdtn/dtn configurations indicates an extra paper tray, so the difference is paper capacity, not print quality or consumables.

My C5900dn shows a toner error right after installing a new cartridge — what now?

Remove the 43381901–43381904 cartridge and reinstall it firmly — most “new cartridge” errors are seating issues, not defective cartridges. Also confirm the protective seals and tape were fully removed. If the error persists with the cartridge correctly installed, try another cartridge to isolate whether the issue is the cartridge or the printer's sensor.
