C-0204 error on C350

[ismail]

I had this error 2 weeks ago but it turned ok. now i have the same error again and it is not fixing and i can't do nothing. I look at second tray and first tray and there is no paper jam. i looked carefully inside the right door and there is no paper or anything jammed there also. Where i must i look? Any suggestion?

its almost always a bent needle on the charge electrode stabbing into the cleaner. I have had long hair end up in there before too. (not mine)

thanks for your suggestion. i took out the yellow IU, open it and clean it but not fixed. any other suggestion?

Fixed. i don't know how, but it is ok. i pull out the yellow IU several times, and it get fixed when i pulled the waste box out and in. i dont know if there is something about that two, but after is ok . Now i have the C-0F3A. And as i see, it is worse. any solution for that?
