Ballendo,
I have done this on an HP 7150. I have not tried with my epson color 800.
Someone mentioned using a scanner chassis to act as the X axis, instead
of sheet
feeding. You could put an aim point or jig on the bottom to hold the
part e.g.: flush
left for top, flush right for bottom. I know that most error I've seen
has been from
page feed, not print head repeatability. On the HP, I did get pretty
good alignment,
but I have not looked at it lately. I'll try and print a 2 sided board
out tonight.
