I think very along this lines.
however in one of the recent links provided there is written about this:
if the detach wire would have a dc voltage it would smear the image.
so it has a ac voltage.
Now, i really wonder a lot about this statement....
But my IIID has no detach, and we need none because the copper is flat.
Still, the charge equalizes, and is a dc charge (of course).
so why then should a dc detach smear the image and a dc transfer not?
strange things are happening in there. most likely dark magic really...
I somehow doubt the toner density can be increased so much that there is
enoug
even if only half is transferred. (nice sentence...)
I wonder if the charge needs to be really high, i do not know how much of
the 6kV
of the corona wire is effectively charged onto the paper, or drum.
maybe a lower voltage works?
the second thing is how to charge the pcb, maybe a piece of wire dragging
over
the surface just before the drum may work.
maybe also a piece of aluminium foil taped onto the surface would work...
(I measured aluminium foil and both sides seem to have no oxyde at all.)
All strange and funny things going on here and i do not really know what
is to be
done now. i will look out for a printer and think in the meanwhile..
maybe we should try to convert a printer to get the pcb charged and see if
there
is more toner transferred....
