Check lower fix roller and check the bearings on it. Could be poor fixing.

Can be more specific please?

I found that they add some kind of coating on damage part of the roller so it can be still in use without having to give marks on the paper. ( I didnt ask what kind of coating is that, possibly its commonly used by used copier business to prolong the life of the fixing roller)

and because that coating, the pressure on the roller is sometimes not even which can make the problem like I posted before.

unfortunatelly I am not have the picture right now so it can be seen clearly.
