The fuser runs so slow it doesn't get out molten.

I tried a hot peel but it failed. (ripped off the toner).

strangely the top-side legend adheres perectly (on etched away copper - 
2-sided stock..).

I don't even bother cleaning much or taking care not to touch the printed 
paper with the
fingers, it adheres very well all the same on the epoxy.

I found the toner slightly "absorbs" into the epoxy (clean it off again, 
it doesn't go
away fully...).
