A question to all the experts here. I just developed and scanned a batch of negatives, and quite a few have long thin scratches across the negative. It looks like this (scanned as positive):

This is the first time that I see these kind of scratches in so many negs. What did I do wrong?
The negs are TMAX 400 and they were loaded in Grafmatic holders, developed in Jobo 2500 tubes. That is my normal procedure. What I did different this time: the negs are from a longer trip and I unloaded the exposed negs from the holder and stored them in an empty sheet film box for the trip home (no x-ray involved).
I guess the scratches must be related to the unloading and storing the sheets in the film box. I don't think it is a faulty Grafmatic because the scratches are visible on sheets from more than one holder.
Any suggestions how I can avoid this in the future?
Thanks in advance
