_sane.error: Error during device I/O

This happens when attempting to scan while there's a jam in the ADF -- should maybe prompt the user to check for a jam then confirm all-clear so we can try again.

Also appears to happen w/o a jam -- should maybe retry once and if we get another I/O error, then prompt the user to clear a potential jam.
