Take out the yellow dev unit, has it lost its developer?
If so then most likely you have blocked airflow.

[QUOTE = mrfuser; 1488936] Tenemos un cliente con un c284e que estaba perdiendo amarillo, por lo que reemplazamos el tambor amarillo y el desarrollador y eso pareció funcionar por un tiempo y luego regresó. También reemplazamos el conjunto de itb, limpiamos los sensores, limpiamos el conjunto de la sub tolva y volvió a funcionar bien y luego, después de una semana, comenzó a perder nuevamente. Ahora parece lavar todos los colores y el amarillo se ha ido casi por completo.
Lo vimos agregando tóner y los niveles son aproximadamente del 2%, excepto el amarillo al 8%.
alguna idea? [/ CITA]
Good day:
I recommend you check the HV BOARD and the Sockets.
If this is stopping you very often it must be that some transistor of the HV BOARD must be working badly.
This is also caused by the Sockets, I suggest isolating it.
Any questions write to my email walvaradocruz@gmail.com

Ok replaced yellow drums dndv and yellow is super high now and other colors are still washed out and levels show very low. I swapped out the sub hopper assembly and the small gears that mesh at the front don’t seem like they turn like they should to add toner down to dv unit. Is there a trick to installing the sub hopper? I took it out at least 5 times and put it back with same result.
Sub hopper is usually a very easy fit. Run a TCR auto supply and see if the colours tone up to 6% then run test mode on all colours to see if the hopper refills. I sometimes run it with the exit cover off so I can see if the bottles turn correctly. If you are getting weird issues with density then make sure you clean the IDC sensors and look at replacing the transfer belt/roller. Update firmware and run a gradation adjustment. Are you using official KM toners and are they for the correct model? I have had customer’s fit universal katun toners to a C308 before causing all sorts of density issues.
