Kyocera Ecosys PA2100cx toner issues

[valonqar]

I replaced the flex cables of the drum unit and the developer unit of my Kyocera Ecosys PA2100cx and now I'm finally printing (previously was printing in blank), but there's still some issues about the colors. Once printed a page it starts showing the message "adding toner" and then ask to replace the toner, even tho it is completely full. It happens with genuine toners and compatible toners. Does anyone know how to solve this problem?
Do you guys think it is a problem in the waste toner sensor? I don't know which part of that printer it is located this sensor.

Sounds like the toner supply tubes going through the transfer belt are plugged not allowing the dv units to tone up. Is it all the toners or just a certain color?

All of them, but it happens mostly with C, M and Y. My last print test it is not printing the color cyan, but in the screen keeps saying the toner is low, but it is completely full.

Remove the transfer belt and vac out the toner supply tubes. This will eliminate one potential problem. And by all means do not use compatible toner ......

Thank you ntbann and Larhal ! It seems to resolve one of the problems, it is stopping showing the message "adding toner" all the time and it's printing all the colors. Although, there's some stripes on the printing, which I guess it is coming from the transfer belt.
