I am also trying for the first time, howdo you do the transfer to the slight etched copper board?

I use a different approach, I clean the copper with something likeDutch cleaner then I put the board in the acid etchant and the copper will turndarker, just a few seconds to maybe 15 seconds. I remove the board rinse it offand then do the transfer. The toner sticks so good that if I use shinny photopaper all I need to do is just peel off the paper and the toner will stay onthe board. Since I started to do this I have never had a failure. So a shortpre etch makes all the difference in the world for me.

I tried it a different way – I took pages from a Hot Rodmagazine I have (slightly glossier than the pages I was using from my othermag). I then printed off the two boards I’m trying to transfer ontoregular paper, then put those in my Minolta copier (which has original Minoltatoner) and then copied to the magazine paper.
I did about 5 minutes of solid ironing on each. Idid not however try freezing the paper (my method was to just scrub it with aplastic scrub brush under water – seems to work fine. And again, it’salways the same.. I get about 80% including really, really fine details butthere’s always just a bit missing in one area or another.
Does that toner transfer paper make anydifference? I mean, I’ve seen this method work with magazine pages prettyquickly in youtube videos, however the PCBs people do tend to be quitesmall. Mine are bigger than the iron surface.
I’ll scrub the board down again and try one more timewith freezing.. I just hate that I can’t see or tell if the toner hasadhered properly before I start peeling away.

My own take on that is remanufactured toner is probablydifferent. It may melt at higher or low temperatures than the real deal.
The only way you can know is to try it, and if it works,hope that the next cartridge works just the same. There is probably moreconsistency with the manufacturers toner.
As I suggested in my previous. Forget using the acetone.

Thanks muchly and one other question if I may.. does itmake any difference using original vs reman/compatible toner? I havecompatible right now. The only thing I have with original toner is my bigMinolta copier.
Also just a clarification.. if I use Comet and thenacetone won’t that leave me in the same place with respect to oils?
