Kent, I just realized what is the problem. The first time I read your post I missed that you were using a JOBO processor. The constant agitation of the developer oxidizes it too quickly, and therefore the developer becomes exhausted before development is complete. There are several solutions to this, but the simplest is to increase the developer concentration 50-100%. This should work, but it may increase fog and or grain. So you could also experiment with increasing only the "A" (I'm assuming "A" contains the pyro.) portion of the formula, while keeping the other quantities the same.(posted 8353 days ago)Another alternative is to buy or make Rollo Pyro, which was designed specifically for rotary processors.
