The other common failure point besides what you have already checked is the imaging drum; as they age, this can occur over time, especially in older models where the drums did not have the endurance they do now where more modern laser printers design it so that the imaging drum and other parts is independent of the toner to get the per toner cost down and rate these for anything from 12k pages, up to 40k or even 60k+ pages (ex: the Lexmark CS drum/developer is split, but good for 150k pages; their common mono lasers hover at 40k or 60k with ones that need a freight delivery going far beyond that at times).

Okidata and Brother has always done this split drum design for years, even when the others built it into the toner carts.[br]
Once the durability was good enough for it, the holdouts (even Lexmark) began to switch over on NEW models, except HP's Canon engine lineup. The legacy machines like the office sized Optras still combined it for a long time (as well as the ones which shipped as a unit because you can't easily change it to split parts; even with how they built those Optra toners being easily split for refilling). Some have ALWAYS been like this like the large Lexmark color lasers (such as the legacy Optra Color series, CS, CX, models which require a freight delivery) and Oki lasers.

I've run into this issue a few times on Reman HP 80X toners as well as with my M401 due to the fact they reuse old drums in those things to cut costs. Based on what you are describing I suspect the Cyan imaging drum did not age well but the rest somehow did.

Given the age of the C9400 (and Okidata no longer selling in the US) [link|https://www.oki.com/us/printing/support/consumables-and-accessories/color/index.html|Okidata no longer sells consumables, drums, users, or transfer belts for yours|new_window=true], you may need to look on the secondary market. That said, you can probably find a compatible/remanufactured/OEM NOS imaging drum for these for ~$50 or so ***(P/N for the Cyan drum is 41514707),*** and try your luck. Sometimes if the unit is otherwise good but a potential future nightmare it MIGHT BE worth throwing a little bit of money at it to see if you can push a bit of extra runtime out of it even with things like consumable sales being a thing of the past.

This idea of buying NOS drums or doing home rebuilds isn't new; it's been done forever and when someone has an old model like the Samsung CLP-300 the OEM drum and toners were discontinued with the HP buyout of the printer division. They continue to produce the newer toner design since they use it in the newer Samsung engine lasers; but not the CLP-300 style toner and older.
These workarounds still have limitations; once the supply of easily available drums Oki stopped making are gone, that's it; you're done once it's also worn out and can't find another. Even the fuser and transfer belt is considered "consumable" in Oki lasers, so you can only do this stuff for so long.

The other common failure point besides what you have already checked is the imaging drum; as they age, this can occur over time, especially in older models where the drums did not have the endurance they do now where more modern laser printers sometimes split the drum from the toner and consider the drum a secondary consumable that you use for a while (ex: the Lexmark CS drum/developer is good for 150k pages, and the Lexmark mono lasers are usually ~40-60k per drum). Okidata has always done it when the drums weren't as long-lasting but was also been a thing with Brother for decades. Even some of the later compact Lexmark mono lasers went this way early on besides most older Optras which shipped a modular "all-in-one" toner. For color, Lexmark has always done it on the high-end color models but uses "all-in-one toner" on the lower-end and mid-spec models).[br]

Sometimes people even rebuild these old Samsung drums as well or shift things like the Cyan charge roller to black if need be, just to give you an idea of how creative you can get to push these a bit further. At some point it comes time to write the printer off and stop with these "hacks", especially when it will be a challenge to source what you need; especially if you can't fix it with a toner shake or even a reman drum. Being Oki makes every key part in the color print process consumable, you MAY have a problem in the future finding parts if something like the transfer belt goes and it's not a drum or toner issue.

Sometimes people even rebuild these old Samsung drums as well or shift things like the Cyan charge roller to black if need be, just to give you an idea of how creative you can get to push these a bit further. At some point it comes time to write the printer off and stop with these "hacks", especially when it will be a challenge to source what you need; especially if you can't fix it with a toner shake or even a reman drum :(. Being Oki makes every key part in the color print process consumable, you MAY have a problem in the future finding parts if something like the transfer belt goes and it's not a drum or toner issue.
I would shake the toner and see if that helps; sometimes when laser printers sit this occurs when they settle or the toner gets too low. While it is rare, sometimes moisture in the air wrecks the toner.
The other common failure point besides what you have already checked is the imaging drum; as they age, this can occur over time, especially in older models where the drums did not have the endurance they do now where more modern laser printers sometimes split the drum from the toner and consider the drum a secondary consumable (which is the setup Okidata has always done but was also been a thing with Brother for decades. Even some of the later compact Lexmark mono lasers did it early on besides a lot of older Optras which shipped it as an "all-in-one" toner but built it to be modular; color Lexmarks have always done it on the high-end models, but do "all-in-one toner" on the lower end and mid-spec models).[br]

I've run into this a few times on reman HP 80X toner as well with my M401 due to the fact they reuse old drums in those things to cut cost. Based on what you are describing I suspect the Cyan imaging drum did not age well but the rest somehow did.

Given the age of the C9400 (and Okidata no longer selling in the US) [https://www.oki.com/us/printing/support/consumables-and-accessories/color/index.html|Okidata no longer sells consumables, drums, fusers or transfer belts|new_window=true], but you can probably find a compatible/remanufactured imaging drum for these like people do for other models which this stuff has been discontinued like like Samsung CLP-300 and older supplies when HP bought the Samsung printer division; people just either rebuild those older drums found in the old machines like the CLP-300, shift parts or scrap them when they go bad since HP stopped making both the toner and drum for the CLP-300, for example. It may be better to write this one off if you can't fix it with a toner shake or even a reman drum :(.

Given the age of the C9400 (and Okidata no longer selling in the US) [link|https://www.oki.com/us/printing/support/consumables-and-accessories/color/index.html|Okidata no longer sells consumables, drums, users, or transfer belts for yours.|new_window=true] That said, you can probably find a compatible/remanufactured imaging drum for these for like $50 or so, and try your luck. Sometimes if the unit is otherwise good but a potential future nightmare it is sometimes worth throwing a little bit of money at it to see if you can push a bit of extra runtime out of it even with things like consumable sales being a thing of the past. It's something I know people do for other Samsung models like the CLP-300 as well; HP stopped making the toner and drum when they bought Samsung, but kept the production of the later "flat slide-in toner" available since they based their cheap lasers on that for color models and some all-in-one toners because again, they use it on their low-cost non-Canon engine machines.[br]
