How to create "Face in the copier" - effect?

[SIZE=2]Hi!
I´m trying to create a classical “face in the photocopier” - picture, and I could use some advice along the road. Originally the images are scanned, in color and quite dark (I think that gives me a better material to work with, head down in the copier consistently made pictures to dark for my purposes). I´d like to have a graphical and rough look - the cliché of face in the copier. Anybody has an idea of how to get that?
Thanks!
