Welcome aboard!
I can't really answer your question; I *think* that a somewhat similar issue popped up recently, which turned out to be a hardware defect in the scanner and Epson replaced it under warranty...if my memory serves. I can't find that thread right now, though.
On a different note; you mention you're from Venice - perhaps you could help the person with this question: https://www.photrio.com/forum/threads/35mm-film-processing-near-venice-italy.206792 I tried to assist using Google, but since you're actually in Venice, your advice would be more useful!
