I have an ADF scanner that failed to scan documents, from one day to the next.

On one side (the front side), a zone is completely dark gray, about 5cm wide:

The reverse side is okay:

Do you have experience with this kind of device? I haven't disassembled the scanner yet. Viewing some videos, I carefully cleaned the sensor's glass with a paper towel and isopropyl alcohol, with no luck: nothing changed. I suppose the gray zone is too wide to be caused by a dirty glass.

Thank you in advance for your help!
