Thanks for bringing this up. As this is definitely related to the hardware used (a lot of scanners do not have such a button) I will paste the following text, even if not all of it applies here.
About xsane: "scanned a blank page": was this because you actually scanned a blank page or because something else is broken? ============================================================== 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!

So it is possible that simple scan has not verify the lock button. It could damage the scanner. I tried the same experience with xsane, there was none strange noise and it scan just a blank page. It is the same comportment on Windows with the Canon's software.
