   Yep I was thinking resistor but the plastic or foam would be perfect, and 
lots easier to come by than resistors of the right values and voltages.  It's 
large ohms per square inch, but should still charge up to a floating voltage 
with no problems.  Should be exactly what's called for, and nothing more needed 
than a piece of HV wire stuck in it and taken down to the corona wire.  Most 
conductive foam I know of is in the megaohm per inch range so should work well, 
assume the other anti-static plastics are too.
   I'm still halfway expecting my printer to blow up since this is so 
non-standard, but so far now this really shouldn't be a big deal over what's 
normally going on with the sheet of paper.  I've got to pull down the older 
lasers I have just to see if the paths are any straighter though, I'll feel 
better about the experimenting with something I don't print with much.  Actually 
I have a 1200 DPI older laser in the attic too, got it for $5 at the local 
hamfest since it was so heavy and gives an error code.  Never even really looked 
at it though, only got it because I know the drums cost hundreds for it, but 
never sold it off.  Time to take a look I think..
