I can get Brother and HP drum units and toner cartridges from our printers at work, after they are used.
I see one very small circuit board with a little plated gold. Does anyone know what the other metals are?

A long time ago a copier tech told me the spool of corona wire used to replace broken charge transfer wires was a platinum alloy. It just so happens he gave me a roll of the replacement wire the same day. He said it was worth $400 that was back in the late eighties or early ninties. I tried to confirm this with internet searches but haven't had much luck. Maybe I should dissolve a length of it an see what it contains?
