Homebrew PCBs

That's a good idea:
  Also I always print the board border when

The fuser in the printer i have uses one aluminium teflon coated roller, 
heated, on the toner side,
and one orange rubber roller (also coated in some way) on the lower, back 
of paper side.

The rubber roller is not heated i think, it's just for counterpressure.

I've seen this arangement in any prnter / copier i've looked in, always one 
aluminium/teflon, heated and
one rubber.


No idea what will happen if i use the teflon roller on the 
paper/toner/copper contact side.
maybe if the pcb is not flat it will not work.

But using the rubber roller on the "interesting" side is not of much use 
too... (not heated)


As soon as time allows i will try different thing, I've bought the paper 
already and not much other use
for it so i can experiment with the parameters.

I will also get the hp toner on ebay (missed the first one - ended at only 
5 eur but i forgot to look after the
auction) I definitely know the toner i have is scrap.


but the number of runs in the fuser is a great help. speeds up trying if 
you have something to start with.


thanks
