Developing problem TMAX 400 with D76

I don't see above whether this is the older emulsion (TMY) or the new TMY-2. Now that you say it's from a 100' roll, it could be a problem with your loader. I'm not saying Kodak has never had a problem with film, but they are the last company I would suspect of having missed something like this in QC.
 
Are you using a chemical stop? I had this problem (white spots in dark areas) while using a chemical stop (a Foma product) and someone suggested that the stop might be to blame. I tried several rolls with a water stop instead and the spots disappeared completely. I can't claim to understand why, except that the omission of the chemical stop ended the problem.
 
I only get these black specks in these rolls of Tmax 400 film...any other film I develop come out just fine no matter the format or age of film...
Next time I'll try a roll of Tmax and Neopan together...to see how that turns out...I'm pretty sure the specks will be on the Tmax and the Neopan nice and clean...
 
Rodinal 1+50 for 12 minutes, water wash for 1 minute, Kodak fixer for 10 minutes, rinse in running water for 5 minutes then let it sit in water until the purple/pinkish haze clears, PhotoFlo (very diluted) for 1 minute...hang to dry untouched...
I'm thinking of developing an unexposed roll to see how that turns out...

Silver precipitates from previous films and resides in the bottom of the fixer bottle and sticks to the next film. Wash all day and it is still there.

Look for black flecks in the bottom.

It s not film or developer.

Either that or crud in the water or both. Water and air filters and one time use of fix are the cure. Use up the fix on test prints.

Wash out the fix bottle, and/or change to glass, and use the fix for 24 hours max for film after the first use.

If that were the case it should happen to all the film I develop...it doesn't...it just happens to the Tmax film...not the Neopan (120) or Arista or LegacyPro (35mm) Maybe I should buy a fresh roll of Tmax 400 and develop it that same way I've done the others...:)

As Sam said, this should affect all films. And in the case of saturnales' experience, the particles are embedded on a series of frames (2-3-4), then everything is OK. That doesn't sound like precipitate to me, though I could be wrong.
 
We can't blame Kodak without emulsion numbers.

Too many people have used too much TMY & TMY-2 with perfect reuslts to blame the film.
 
I have had that problem with fixer I had used a few times then it sat for several months before giving the spots. Solved it by filtering the fixer. Probably will dump it before using it again.
 
Just when things were going good for me with Tmax400, now you give me something to lie awake and worry about. Saturnales; please post your solution to this problem if you find one.
