Every 3rd or 4th print, I get some streaking across the paper. The streaking is rather light, and I believe it is uneven developer flow, or possibly uneven stop bath flow. The streaks are always toward the end of the paper that is against the bottom of the drum and run across the print. Jobo CPA2, with 2830 drum, only on 8x10 prints. I have tried prewashing the prints, but still get the occasional streaks. Any thoughts on what I might be doing wrong, or may be missing?
