Re: Bizhub C250i Fuser noise

Hi, are you sure the noise really comes from the fuser/exit section? I had this problem a while ago, and i was pretty sure i came from this area. I was wrong.
I removed the waste toner transport section above the waste toner box, and there was a pile of toner on the inlet port and inside the machine. For some reason the port didn`t open when the transport section was installed.
It has to be installed absolutely horisontal, otherwise the inlet port won`t open correctly.
I cleaned out the leaked toner and installed the transport section/ waste toner box correctly and the noise was gone.

This is common on these and noise can't be mistaken with fuser/exit section noise. They changed some covers shape but advice is to install wtb transport section (upper part) together with actual wtb(lower part). Another I think separate issue with them is when toner rocks blok transfer belt cleaning section, usually customers call for CQ symptoms as blocked section dumps toner on belt and consequently onto paper.
