Good morning!! During the last weekend of May I mixed a batch of RA-4 chemisty in 10L containers. I used a Fujimoto table top processor with exceptional results. When I was finished I drained the chemisty, rinsed the processor, removed and rinsed the rollers. Last night I filled the processor with some of the chemisty that I had mixed during the last session. Using the same paper that I had gotten terrific results with last time I was shocked to see that all photos I tried to print last night had a severe green cast, even under the border. Thinking that my "expired" paper may have actually expired I opened another box of paper (different manufacturer) and these results were the same, except instead of a green cast I got an almost black cast. So has my paper gone "bad", has my chemistry expired or were my cleaning skills not up to par??
