We Thunderscan users are VERY familiar with that particular problem... :-)

It's actually pretty easy. Remove the ribbon. Slide the print head to the 
middle where it will be easy to work with. There's a little black plastic
key behind the print head (where "front" = the end closest to the paper);
hold it back with one hand and with the other, grab the print head firmly
and pull it straight up. It takes a firm pull, a little harder than pulling
a card out of a nubus slot. Then you can get at the tiny screws that hold
the plastic guide on.  

I used to just carve away the folded part of the silver foil with an
Xacto knife, but after three times I got wise and just pulled the whole
thing off. Didn't make any difference that I could tell--if you have
problems with ribbon smearing onto paper, you might use the adjuster
to move the head back one notch.
