I'm starting to look more closely at scanner troubleshooting issues for deployment. Is there a utility or command parameter that will instruct a scanner to park the head back in the home position and generally reset itself to a safe/ready state?
My everyday flatbed scanner ((vendor=0x04a9 [Canon], product=0x220d [CanoScan], chip=LM9832/3) at libusb:002:002) got out of sorts today. The scan head wasn't returned to the home position (it is now), but XSane scans now just return solid black data. The Lide20 has been pretty reliable. The only thing out of the ordinary today was that I ran the scanimage program for scanner information. I usually use xsane with gimp, and unplug the scanner shortly thereafter. Is this a hardware state problem, or a crashed kernel module that must be purged (and how to do so?) Nothing sane-related shows up with lsmod. Thanks.
