Scratches on nylon side of home deloped film -Mju II

[Perks]

Hi All,

I have discovered that I am getting scratches on the non-emulsion side of films run through my MJUii.
I have not squeegeed or otherwise touched it, I am pretty sure it's not the negative sleeve.

When I open the back Nothing strikes me as problematic, but i cant rotate the roller. Also the Panorama 'blinds' don't seem to close if that is important.

Does anyone else have this problem or a solution?

Cheers.

I should note that what I am seeing is very a single fine straight scratch running along bottom third of the length of the film when scanned, but becoming less pronounced as I move through the roll, not visible in the scan by frame 19. But multiple scratches remain along the back.

I am beginning to suspect it is the rollers mounted the door that, I guess, help to keep the film tightly wound on the uptake spool.

Nothing appears amiss, but I have wiped them and around the uptake spool and blown some air into the back. I am now trying another roll.

No one else has had scratches on the base of their films?

If this pattern of very regular straight lines is the same on each film then it is the camera. If it is different each time then it is something else caused by either dirt in the cassettes, (especially if reusable), or bad technique, but since you do not squeegee then this is less likely. Have a close look at the presure plate and see if it is damaged and also as you already said the rollers.

Thanks for the response. I checked a few older scans and found that the scratches are of the same character, but not in the same location. Commercial rolls only, no bulk loads.

The lines are very straight, running across multiple frames, but do not match across different films.

I will report back once this roll is processed.
Hopefully it was grit which I have removed.

Hi, Question, do you pull the film out of the mouth of the cartridge or you open it and get the film out complete.

cheers

Thanks, it s limited to this camera only, but I do open the top of my film cans and pull the roll out in the dark bag.

I still suspect the rollers or pressure plate or that peice of flexible metal close to the uptake spool, but can't reconcile the different locations on different rolls. I will post examples when I get a chance.

Here is an example of the scratches.

I have just developed a new roll after cleaning the suspect areas so will check that tomorrow.

New roll: Still present in scans, but thinner. I am pretty sure its the rollers, will try reduce their pressure on the film and just use that camera less.
