Hi Herbert,

The original idea came from a subscriber to the list who was IIRC an
EE professor at Oregon or Washington and posted his procedure for
making  printed circuit boards using a Xerox Phaser solid ink printer.
 It's in the archives, but the 'gotcha' is that the cheapest Xerox
solid ink printer starts at $2400!   I found one a year later for $50
at a business closing and remembered the post.  The only mods needed
are are to trim a little plastic to make the 'paper' path for the PCB
easier and I imagine the mods would be specific to each type of machine.

The solid ink holds up really well with Adam's CuCL etching system.
All I do is scrub the copper with Cameo copper cleaner before printing
and then etch.  The board is done in about half a hour.

If you look for Xerox Phaser printers make sure you are looking at a
solid ink printer as Xerox sells some low priced laser printers under
the Phaser name.
