People have written me that have 2 roller laminators with a similar
setup to that that tell me that it works OK. (Still both hard
rollers; heat on one side though.)

(My laminator has 4 rollers with 2 heat elements in the middle
(top/bottom)) The bottom element is slightly hotter though...

Thats the only way you get anywhere... But honestly; I didn't have
to experiment that much after I started using the laminator. The 2nd
attempt using it was nearly perfect. After that there is some
fiddling with the number of passes that each new size/board takes.
IE a .5 oz 2"x2" (~6-8 passes) is different from a 2 oz 4"x6" (10-12
passes).

My genuine HP 5L toner works great --1 pass through the printer for
an image --6-12 passes (+copper clad) through the laminator.
