Please report any bugs in English language.
I convert this into a Question, that can be in French.
Also this might be solved by some (google) search.

Also, before reconverting into a bug, please read the following:

Hi there,

thank you for filing this bug and showing your interest in Simple Scan!

This seems to be a Hardware Issue, i.e. Simple Scan does not support your scanner perfectly -- or possibly not at all.

Unfortunately such problems happen more often then they should, and while it might indeed be a problem with Simple Scan, in our experience, most of the time it is not.
This is why we prepared a check-list at [1] that will let you find out whether or not it really is a problem with Simple Scan and what your options are in either case.

Please read that list and tell us how you decided to proceed. I will set this bug to "Incomplete", so a friendly robot will expire this bug in 60 days if you do not respond. However, we would really prefer to hear back from you!

Best Regards
Michael
