Vertical lines going through my BW negative

Here it is. I've included a pic. Let me know what you think is the cause of this. Shooting it with a new camera but doubt thats the problem. Its TMax film developed in TMax for 6 3/4 min and agitated every 30 seconds for 5 seconds.

ok looks like it is a mechanical problem?

(there was a url link here which no longer exists)

Is this visible on the negative, or is this a bad scan? For problem diagnosis, it is usually helpful to attach a digi-photo of the negative, showing edges, and not reversed. Also, film-format and camera model might be useful too.

Edit: My apologies for using the s-word and the d-word. Both of these appear to trigger an automatic Forum-Warning.

Scratches from the film transport? I've also seen that from the glass surface of the sc*nner being dirty.

Hey guys thanks for the feedback. Its definitely visible on the negative and my scanner glass is fine because i did some scan recently and nothing like this popped up. ok so Im using a Yashica 124g TLR and as I've reported on another thread when loaded with film the film advance is very tight and now these lines on my negs so I'm guessing its definitely the film transport?

I'd suggest that it's the film rollers sticking ? (I had a similar fault a few years ago with an old 35mm I'd been given. The pressure plate and the whole transport was so tight that the film was affected on both sides, the back with scratches and the emulsion with lines after development.)

Try lining up the processed film with the film track in the camera, look for any rough surfaces, sticking rollers, tight pressure plate, or stiffness or lack of smoothness in the film advance.

You should be able to feel whatever is causing those plowed furrows in the film transport, the rollers would be my first guess.

The lines are in the direction of the film transport. Could it be that the camera back is pressing too hard on the film? I could imagine that when the film is pressed too tight and it takes a lot of force to move it it will somewhere get damaged.

ok if its the rollers or the pressure plate then that means I have to take this camera in for service right?

Hey guys i think I know what the problem is and will run another roll to see how it goes. thanks again for all the input.

Do not now if the 124 has a pressure plate that can be rotated to accommodate 120 or 220 film ?

My 124 has the rotating plate for 120 or 220.
But this would be a roller failure unless it was 220 film.

Have a careful check before you incur the cost of service....might just be dirt or a paper fragment causing the rollers to stick.

And, yes, the 124G does have an adjustable pressure plate for 120/220....check that this is set, and seated in place, properly. Also "feel" the film wind, is it smooth and easy to operate, or do you have to force the winding lever unusually hard. Is it easier when the camera is empty, then unusually stiff when a film is loaded ?
(I have a 124G and it's quite smooth and easy to wind on when a film is correctly loaded.)

I was thinking that if the plate was in the 220 position when using 120 film it might squeeze the film to tight as 120 is thicker with the paper backing than 220 which does not have the paper backing.
