Re:laser jet consistency and registration

2004-04-29 by Richard Mustakos

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.
Richard
