    c754e cyan imaging unit problems

    Good morning.
    Any kind of help will be welcome...
    The cyan imaging unit for some reason spills all the developer out and into the waste toner container. 3 days ago we changed the development unit for a new one with its initialization chip. The machine was working perfectly. Today the client contacted us with the same problem. We have reinstalled another new developing unit and changed the toner (original). The machine has worked perfectly again, but we think that the machine may have some type of more serious failure and that within 3 days it will fail again.
    Any help is appreciated

    Buenos dias. cualquier tipo de ayuda sera bienvenida.
    La unidad de imagen cian por algun motivo derrama todo el revelador por fuera y al deposito de toner residual.
    Hace 3 dias cambiamos la unidad de revelado por una nueva con su chip de inicializacion. La maquina quedo funcionando perfectamente. Hoy nos ha avisado el cliente con el mismo problema. Hemos vuelto a instalar otra unidad de revelado nueva y hemos cambiado el toner (original), La maquina ha vuelto a funcionar perfectamente, pero pensamos que la maquina puede tener algun tipo de fallo mas grave y que dentro de 3 dias vuelva a fallar.
    Se agradece cualquier ayuda
    Gracias

      Try this thread, there is a PDF in there detailing Cyan/Magenta dev problems on this series of machine.

      It could be the toner vac system at the rear of the DV units that is blocked or the Toner Filter is chocked full. This will cause the Dev unit to "spit" toner onto the drum / charge grid causing the image defect you have provided.

      If I ever replace a Dev on this series of machine I always replace the Drum at the same time, these machines are notorious for C Dev issues.

          The cyan drum & developer should unit come as on unt, they are not designed to be replaced separately, if you are using a non OEM dev unit this could be your issue.

          Let us eat, drink, and be merry, because tomorrow we may die!

              If the HVT is bad you can get these symptoms.
              If you'd like a serious answer to your request:
              1) demonstrate that you've read the manual
              2) demonstrate that you made some attempt to fix it.
              3) if you're going to ask about jams include the jam code.
              4) if you're going to ask about an error code include the error code.
              5) You are the person onsite. Only you can make observations.
