here it is (I scanned the whole scanner area). It appears so strong. It clearly cannot be neglected :(...

What do you mean ? I am a true beginner, but when we have no film, the result is all black right ? :confused:

Yes, as i said it is !! And a scan without any folder and film also has these light regularly bands. But i cannot imagine that it is a normal behavior.

FYI The scanner is pretty new and has almost never been used :/. Is your explanation still relevant ?

Thank you for your answers. FYI, here is two frames with better resolution. But, as suggested (don't know why I did not though about it before), I did an empty scan, and, with the restricted area of the 120 frame, here is what i get, after tweaks to increase the visibility of the bands: So it is clear that it does not come from the film/holder, but from the scanner itself. It is pretty annoying, as i bought the scanner from a particular. Hopefully I still have an available warranty. Do you have still an idea about where it can technically come from ? It can help me if I have to demand a repair/replacement. Thank you [EDIT] and yes, the film was underexposed ... as this was my first try with my Yashica :P

Hello everyone. I recetly bough a Epson v850 scanner, to be able to scan my 120 films. Unfortunately, i have until now a pretty annoying problem, as we notice huge vertical bands, specially in the dark areas, with both silversfast and epson scan softwares : Do you think that it just comes from the fact that the film is not so flat, or a more complex hardware issue ? Thank you in advance for your feedbacks.
