I almost did it with a pcb too.
then i thought maybe it harms the fuser, and i only have on replacement,
and i
really like the IIID.

I think the copper isn't charged.
i think the corona wire can't charge it. i think it is at ground level.
BUT i think the toner comes off from the positive drum to the zero pcb, at
least
a part, all by itself.
Maybe the result could be much better if we really put it on a isolated
carriage
and charge it all up.
The fuser will most likely not have enough time to heat it well.
this is the reason why i suggested infrared heaters.
they are easy to install, and there is no danger that you smear the toner.
What i fear is the pcb will damage the drum, i think a slight distance
would still work.
(e.g. if you tack on a thick paper with tape on a thin paper the printing
still works on the
thin paper (where there is a step, and a small distance).
If you make a flat carriage it is easy to keep this distance (well, if the
pcb is flat).
Good deburring is a mst here, and maybe even place a piece of tape over
the edges.
See if you can get a picture, i fully understand the ney sayers, i was
convinced too.
