Hi I'm sorry to hear that.
The advice they gave is good. But, given your specific problem I would try replacing just the roller first as that might very well fix this. I have sen this many times be the issue and you looking at it confirmed that as well ;-)
I agree with you replace the roller only and likely that will solve this it really doesn't sound like the fuser lol.
In any case, I will stick with you until this is complete.
