4X5 negative surge lines using Jobo Processor

greenspun.com : LUSENET : Black_and_White_Photography : One Thread

I am using a Jobo tank holding 6 4X5 negatives. I insert them with the long side up and the emulsion side in. Have also tried narrow side up with same problem. Neg is placed about 1/2 inch below lip of tube. On some negatives (not all) I'm getting a surge(?) line along the narrow edge which comes down from the top corner and ends up about a 1/4 inch in on the bottom edge. Anybody have a solution for this? Thanks.
