No, it's genious.

There's the problem!
I'm going to ask a friend of mine...  He is fiddling around some university
right now.  Head of some chemic thing.
He should have atleast one idea.

I've already pumped some different solutions in mine.
One was a UV-fuorecent oil.  (That actually worked out really well btw.)

I have solved it two years ago, when I fisrt saw a straight-paper-path
laser-printer for use with cardboard.
As soon as I'm finished with this little project I'm working on I'll find a
inkjet with same design.
