$ scanimage
scanimage: sane_start: Document feeder out of documents
scanimage: Received signal 15
scanimage: Trying to stop scanner
scanimage: Received signal 15
scanimage: Aborting

There may be a "status" of some kind I can check from SANE without
crashing before I try scanning but I haven't found it yet.

Is there any way to prevent this from killing my server in the
meantime or is "catch" the biggest gun I have for that?

Thanks,
