Hi Rob,

I wonder if you could expand on your instructions?

You print twice, once on card stock and again on the PCB material
taped over the first plot.  Is this for double sided  a PCB?  Or is
the pattern transferred fron the card stock to the PCB?

How does the printer hold up under a use that Xerox probably considers
abuse?  How many boards are run through the printer during a term?

Finally does the ink stand up to the CuCl + H2O2 etching as used by
many in this group?

Since the bottom end Xerox 840 is selling for $999 it could be an
ideal solution for homebrewers.
