It is possible that you do have a temperature problem.
Laminators without separate temperature control sometimes do not get hot
enough to fully melt the toner. Also, some of the new toner formulations
require a lot higher temperature to fuse correctly.
I've never tried, your combination of toner and laminator, so let's hope it
is just a matter of cleaning the copper properly.
d\Definitely try the "flash fusing" with a hair dryer about 1/4" above the
pcb.
