    Re: C308 intermittent noise

    Yeah, that definitely sounds like the black toner motor trying to turn. Check the black TCR ratio or run some solid black halftone pages and see if the machine can keep up. You can also try running just solid color halftone pages and see if the noise is still present. I don't think the black toner motor would have to turn in this situation. If it is the black toner motor, you'll have to remove the hopper assembly and vacuum out all of the excess toner that is putting a drag on the motor/auger.

    1000% this is black hopper, I recognise this noise anywhere.

    Remove it and lube the gears behind it. Problems solved

    It was the upper exit rollers. I have unmounted the exkt-unit and a little fat was enought to solve the problem.

    Thanks all for tips

    So, you put more tension on driving belt? Many techs here stress on toner drive including EKMT, are you positive about this resolution?

    No, only fat in the bushing and the noise disappered. I don't have idea how the tensin of the driving belt can be changed.
