How did you fix the negatives? In the tube or in tray? And if in a tray with several negatives, did you shuffle the negatives constantly? Fresh fixer is assumed?
The backing on some films, TMY for example, is hard to remove, and if you develop in a tube or in a Jobo very little solution reaches the back of the film. That means that when then film comes out of the tubes there is still a lot of backing that needs to be removed. If you just place the negatives together in a tray and don't give adequate agitation you won't get complete clearing of the back. I have seen marks similar to those on your film from inadequate agitation of the film in the fixing bath.

I fix the negative by placing the tube (with the negative inside) in a container of fix and spinning it vigorously for about 5 minutes, all with the lights off. And the fix can get to the back of the film, because it’s separated from the tube by a thin sheet of fiberglass mesh.
No, fixer was made in July. I don’t do a lot of development, so I've been making a fresh batch every 4 months or so. Is there a rule of thumb on this, like fix x sheets and toss the fix? Or toss the fix after x days / weeks / months?
I'm also curious about the mechanics of how inadequate fixing can produce these lines.

Is it possible these lines are a film defect ? Too regular to be static...then there's that finger like thing.
notch codes ? I only use one film...
Interesting that you mentioned static because I was wondering about this. The film holders were kept for weeks beside my scanner. I was wondering if magnetism from the scanner motor (or something like that) might have affected the unexposed (or exposed) film. I've since moved all my film away from the scanner, not wanting to take a chance.

What caught my eye was the pattern the lines made. They were kinda scalloped. I've never seen anything like from processing but who knows ? It'd be interesting to sacrifice a sheet to see if the scanner is the cause.

I don't believe that a 5 minute fix with the film in drums, even with the mesh, is adequate. And certainly not if the film is TMY. To remove the backing with TMY I fix for up to 10 minutes in tray, and often have to place the film in hypo clear or a 1% sodium sulfite solution to get rid of all of the backing.
With your procedure I can not explain the lines. However, when various sheets of film are fixed in tray, with inadequate shuffling agitation, these kind of lines would not be unexpected.

I don't quite understand this. You are working in a tube, so you would obviously be agitating for the entire time...unless your tubes are completely full and you are standing the tubes up when resting for semi-stand development?agitating 30 sec to start and 10 sec at 11 min.
I used to get similar lines (which was from mottling) when I let the film rest lying in the tube on the counter which was full of developer. I solved this problem by standing it up. I doubt very much that your lines are from static.
Try getting into the habit of fixing your negs in a tray. TMX is very stubborn when it comes to removing the blue backing...

It’s the latter; they stand upright between agitation cycles.
Funny, but there is no blue backing at all left on this neg. The edges are completely clear, apart from the usual pyro stain. When I do get a spot of blue dye left on a negative (which is rare) I just wash in Permawash for another 1-2 min and it disappears.
I wonder if these lines are maybe just a byproduct of stand development; an air bubble or something that caused the ripples. I know one takes a chance with stand development, so maybe this is the 1 time out of 25 it didn’t work out. Still, I think I'll reduce the maximum period without agitation to 8 minutes just as a precaution.

If it only happened to the one sheet then I would attribute it to the photo gremlins and move on...if it happens again, well...then I would reassess my development method. Also when doing stand or semi-stand development it is always wise to expose a backup.
