Second image is a part of the first where the problem is more visible.
I changed fuser unit, transfer belt unit and so one.I tried many different ways to set the paper type on printer driver: as a lighter, or heavier, but nothing solve this problem.I`done
Anyone with more expirience?!
PS: I think this is a fuser problem, but...

Could also be the MOB. Clean it and then swap.
