Re: Electrostatic Toner Transfer

2004-11-13 by gettingalongwouldbenice

I made a Photo Album for Electrostatic Toner Transfer.
Ain't perfect, but was the best I could do in 15 minutes
of experimentation.  I'm dragging my feet on ripping the
fuser out of my laser printer.  I don't make enough boards to justify
a disembowled laser printer taking up space.

I'd much rather find something
that could dissolve the clay remnants from the Staples Picture
Paper.
