Yeah this sucks. I usually use xsane, which still works. But since my post on March 5th, "simple-scan" no longer works. Similar to other reports, clicking "scan" causes the scanner to move around a little, then gives up and says "Failed to scan".

In the meantime, please use "xsane" image scanner (it's more complicated to use, but at least it works).

I'm not sure why simple-scan would stop working, yet xsane still works ... they should theoretically use the same command sequences...
