The time of a pass is dependent on how long the paper/board assembly
is. For the 6x2.75" board it was about 5" and it took around 25
seconds. So you can see, a big board gets tedious

as I said in the original posting, I use an iron to tack it down.
With the paper/board assembly lying flat, I start with the iron in
the middle and go back and forth. This I flip it over and do the
same. It works ok but my wife wants her iron back :)

I may yet build a PCB fuser from an old HP LJII I have but its more
of a project than I want to tackle right now. Besides, I've kind of
been waiting for you to post detailed instructions. lol By the
way, I believe this isn't just my H200 but all H200s.
