Thank you very much. I really like comments like this, it's a great motivation to keep working hard. Really copier printers is a complicated job but as you can see it can bring some fun. Regards from Europe.
This could be a serious problem. Update the copier if you can. If the machine starts, but you can't do anything, disconnect the disk and try to start the copier. If that fails, you'll need to replace the NVRAM or the controller.
Nunca regrese al modo de fábrica porque la impresora tiene configuraciones individuales. Describe exactamente cuál es tu problema. ¿Quizás tengas algún problema con que el plástico encargado de contar el tóner esté mal ajustado?
