Xerox C550 rattle noise

[Paulo Borges]

Hi!

I'm on a C550 who does strong noise in the begining and in the end of each print job. Don't do it during the printing job, so I assume it could be transfer belt arming / desarming related. Recycling / waste toner system was already cleaned.
I barely know this machine.
Can anyone tell me what to check?

Thanks.

Solved.
it was the gears on the transfer roller unit
