Well The good news is it works and it works really really well The
toner is rock hard and fused to the board I have found that slowing
the motro to helps as the board absorbs a lot of heat as it passes
thru the laminator. I found that 220Deg C works well for the feed
rate of my laminator. I am awaiting a roll of toner sensitive film to
arrive as I believe this will stop any bleed thru problems I have
been getting on the larger boards.
