Well then, i thought the same.

BUT why then works Aluminium foil?


What i wanted to do is isolate the PCB so there is no short to ground.
i want to put it on a carriage, of teflon or such, which has the 
appropriate
HV source connected to it. To charge the whole board.
The copper conducts, correct, but it can still hold a charge.


I wonder how bad/good a printer will work if the first corona wire is 
completely
off.
I looked further and the aluminium foil has to short it out, it just has 
to, there
is a grounded area just in front of this wire where it passes between a 
metal roller and
bar.


I will try to unplug the corona wire somehow, and see what happens, but 
this HV wiring is pretty
well covered....
