Okidata C9650HN Toner | Compatible 42918984 Cartridges

C9650HN

The Okidata C9650HN is a high-end networked color laser printer from OKI’s C9650 series, aimed at offices with demanding color print workloads. It runs on black 42918984, cyan 42918983, magenta 42918982 and yellow 42918981 — the 4291898x branch of the 429189 series. One warning worth printing in bold type: the similar 42918901-series cartridges do not substitute for these, despite the near-identical numbers.

Demanding color workloads punish guesswork. On this machine the four part numbers differ by a single final digit, and two similar cartridge series exist side by side, so the discipline that matters is ordering by the full number on the cartridge that came out — never by the number that looks familiar.

Which cartridge should you buy?

Black and yellow are sold as individual cartridges on this page, and black also comes in two-, three- and five-cartridge multipacks — the practical way to stock the cartridge a busy office empties first. Cyan and magenta are not stocked singly here; they arrive in the three-, four-, five-, six- and eight-cartridge color sets, so when one color runs low the set sizes let you restock just the colors or the full range in one order. Whichever route you take, verify the 4291898x numbers on the box against the cartridge you removed before opening it.

Chip, toner and everyday use

You do not need to open the printer to know which cartridge is low: the front-panel display and the status monitor report each of the four cartridges individually, so replace only the color showing low. Each cartridge is chipped; if a replacement is not read, lift it out and reseat it firmly. Keep spares boxed until needed — a high-end machine’s cartridges are worth protecting from dust, heat and light while they wait.

Frequently Asked Questions

What toner does the Oki C9650HN take?

Yellow 42918981, magenta 42918982, cyan 42918983 and black 42918984 — the same set as the rest of the C9650 series. Do not substitute the similar 42918901 series; it is a different cartridge despite the close numbers.

My C9650HN prints fine on plain paper but colors smear on glossy stock. Why?

Glossy and heavy stocks need the correct media type setting so the fuser bonds toner properly. Select the matching paper type in the driver — plain-paper settings on glossy stock cause smearing regardless of toner level.

How do I know which C9650HN cartridge is low without opening the printer?

Check the status monitor or the front-panel display, which reports each of the four cartridges individually. Replace only the color showing low.

Are cyan and magenta sold individually for the C9650HN?

Not on this page — cyan and magenta are stocked in the color sets listed above, while black and yellow are available as single cartridges. The sets carry the same 42918982 and 42918983 cartridges.
