I think the toner might have to be modified a bit to get the board
through. The clearance is very tight.
The transfer voltage should remain connected. It is necessary to
allow the printer to properly clean the drum before and after the
print is made. In effect, while the metal carrier is present the
transfer voltage is shorted out, but there are current limiting
resistors in series with it so it doesn't seem to matter. Early on I
used a high voltage relay to cut it off when the carrier was present,
but I found it wasn't necessary.
