I never met with this problem before, is this fixer problem ? Perhaps I didn't wait long enough or overused ?

I've had that before on 120. The problem was that part of the negative was not fully submerged in developer. SO it got developer splashed on it during agitation and then the residuals dripping off, but no constant contact. Is any emulsion remnant on the negative? Is the problems all on the same side?

Very logical what you said, I will check it out. I made enough developer 1 L it must cover two 120 rolls, I will re-model it and verify rolls , no emulsion remain all looks developed .

I agree with David.
An exhausted fixer problem would not have any true blacks in the image.
The deepest shadows would look hazy and gray sort of like noise in a digital image
The fixer removes residual silver to open up the emulsion and create less or no density in lower tones and dark shadows.
In your samples things look normal in that regard so, the fixer is probably fine.

Hi, there. What about film rinse? I've seen that kind of brown stain on poorly washed prints. If not removed completely the fixer will react oxidizing irreversibly the metallic silver and ending with fading. A good policy is to use hypo clearing agent for the rinse.

Cheers, M.

Finally I did figure out may what did happen. I was 'smart ass' and I did tip off immediately water when running water did reach top Sad
so upper part wasn't rinsed well. To be sure I made fresh fix today and care about rinsing maximum I didn't meet same problem again.
