It's extremely tough once cured, or if left to dry a few hours. Normal  
solvents (acetone) will not cut it, but printer cleaner with ammonia in it  
does get rid of most of it. Mechanically remove the rest (abrasive  
scrubbing).

That would be a lot of work, and i don't see what you'd gain from it? The  
printer electronics work just fine as they are.

Remember they put through a non-trivial amount of data, and timing is  
critical as anything, it would not be as easy to control as a CNC machine  
by far.
