* What led up to the situation?
Started it; could not find scanner.
Plugged in scanner (duh).
Rescan still didn't find scanner.
Relaunching application -> found scanner.
Edited some scanning options (1 bit B/W scans), previewed, scanned and saved
Expanded and shrunk various windows and redid preview scan.
Reduced to 400 dpi.
Tried to select an area to scan. The entire area was highlighted, but several
smaller squares with red borders were also apparent. I might have accidentally
clicked to create them.
Requested scan; the areas with red borders were scanned successively, with me
hitting cancel after each one.
I also hit the red button on the bottom right of the window that showed between
In the main window, right click to deselect all the little squares.
Highlight the overall area to scan.
Request scan. It may be relevant that significant time (1-2 minutes?) had

After a slight delay skanlite reported (roughly) I/O error: unable to contact
device. Note that the application was
open continuously between the time it worked and the time it failed. About this
time kern.log shows the last message below:
