Homebrew PCBs

The thing that seems to work best is disconnecting the transfer 
voltage from the transfer roller and then grounding the surface of 
the pcb. This can be done with a thin wire or conductive copper tape 
(make sure it has conductive adhesive) from the pcb to the carrier, 
then a thin wire from the carrier to ground.

Have you tried that?
