[ARC5] More on Bashless T-17 Microphone Resurrection

[Jim Wiley]

Printer "toner'" as used these days in xerographic copiers and printers 
based on the same principle is, I believe,  a type of powdered plastic.  
The plastic powder melts under the heat of the "fuser", becoming one 
with the paper being printed upon.  There are a number of formulations 
for toner, some including powdered iron and carbon particles.  Some of 
the original formulations were primarily iron oxide, but that has 
changed to powdered plastic for modern machines.   Others may have more 
information.
