Many years ago I built an automatic color print processor. The
hardest part was getting a Laminar Flow across the surface of the
paper so that it would develop evenly. I built a chamber with a lot
of baffles that took the flow from a pump and spread it evenly
through a slit at the top of a ramp where the paper was held. It
worked great, but was only one sided. Doing this on both sides should
be possible, but would take some experimentation.
