Lines running down negatives, another one of those threads...

They don't think that their adjustments fixed it? Great that the problem is gone in any case. Sometimes it's best not to go looking for trouble.

I am getting almost identical lines on my 35mm Fomapan negs. The problem is only on my Foma negs and they have been through both Olympus OMs and my Leica M6 TTLs...
I thought it was a manufacturing problem but now I'm questioning it!
