Frequently Asked Questions
What toner cartridges does the Oki C5450dn use?
The C5450dn uses the 42804501 (black), 42804502 (cyan), 42804503 (magenta) and 42804504 (yellow) cartridges — shared with the C5300, C5400 and C5450n.
Does the C5450dn print double-sided automatically?
Yes — the “dn” suffix means duplex and network are built in. Two-sided printing is automatic once enabled in the driver, which cuts paper consumption in half on long documents without affecting 42804501–42804504 toner usage.
My C5450dn's black prints look gray — how do I get true black?
Make sure the driver is set to black-and-white rather than auto color — in auto mode the printer may build “black” from the 42804502–42804504 color toners, producing a washed-out composite. Forcing mono mode uses pure 42804501 black toner, which prints darker text and stops draining color cartridges.
