It should be possible to figure out if the paper is the problem by  
inspecting the results.
Did the toner stick to the paper? Is it too fibery? Where it transferred,  
are there fibers left or only a white "powder".

If the paper comes off well in some areas, with the right sort of  
grey/white residue left and no (0%) toner left on the paper, in those  
areas, i don't really think the paper is the issue.
With the right pressure and heat you should be able to fuse the toner to  
the board with _any_ paper, the only question beeing if you get the paper  
off without taking the toner with it. But if the toner doesn't even stick  
the problem must be either pressure, temperature, board  
preparation/surface, or some other contamination, but not the paper.

I dunno, it's sure strange, but when i had the problem that it just  
stopped working reliably (with the same paper and material) i decided it  
is my ironing and got the fuser, and the problems went away. I didn't look  
into it then why it suddenly stopped working.

Of course, a paper that works better will be slightly more tolerant  
towards the other factors, but it can't solve a major issue.
