Kyocera FS-C5350DN Printer: Tackling 'Call Service 7404' Post-Y Toner Replacement & Cleaning

Hello.

I have a Kyocera FS-C5350DN printer, which showed a message about the need to replace the Y toner. I replaced the toner and even put 3 different ones and it was still the same. Then I took the printer apart and cleaned it properly, the problem was for sure because the powder was killed in all possible places. After cleaning, the toner traveled freely from the container to the developer, but the message to replace the toner remained. The last thing that came to my mind is to clean the developer. There was a powder inside the developer, but it was brown rather than yellow. The developer was flooded with a new one.

The printer now shows Call Service 7404.

I had the same problem a year ago and the printer went to the service - they fixed it, but it seems that the developers did not replace it (because the powder would be in better condition) and the blue cap is broken (so I conclude that they did not even look there). I think they did a developer reset in service mode and the printer came to life.

People who revived their developer and solved a similar problem, please help and give a specific hint. Thank you.

I understood correctly that you spilled everything out of the developer module. everything that was there and you covered with only powder (toner)?

There is no such thing as a developer reset. Not on these models. It remains to buy a new calling unit Y or look for used ones. In its current state, the printer is a useless piece of furniture. I recommend reading the small colorful kyocer topics here on the forum.

This is how I poured out the old toner and covered the developer with a new one.

Where did you get the developer for FSC5350? Was it a developer dedicated to this model? To my knowledge, there is no powder for this model anywhere.

The only solution is to replace the entire developer module with a new or functional one.

I'm afraid that my colleague got rid of the developer from the developer module and sprinkled only toner (powder).

wrsls-k2, the developer itself is brown, like iron filings, it combines with the toner in the developer module, wrong developer and toner ratios result in error 740x.

Thanks, buddy for the hint, because I didn't even know, now I'm checking and there are actually filings.

jerry74 thanks for the hint.

I crushed the old toner (the brown one) and covered it with the developer.

Problem solved. The printer works.
