Haven't really looked it up but many things are oxidizers. Don't remember
which way to go off hand but should be doable with something from the
supermarket, like baking soda etc. Most things are easy to oxidize and hard to
reverse, shouldn't take much chemical help to make a thin layer.

Yep with more gap and more voltage to hold it on may let it do a bit more,
but too much may smear etc so not sure if it'll be useful much beyond what the
manufacturer designed for. Still shouldn't be hard to try on an old laser.

Yes that would be a very good thing to see, I'll have to hunt up some copper
foil myself and see how it works in my 6L, it's a good little printer. Don't
really want to mess up the drum though, but worth a little risk I suppose. Heck
I rarely use it for anything other than printing PCBs now anyway.
