I did a quick check on my own fedora 21 with my MB5050 and ran into the<br>
same problem. It turned out to be caused by some confusion caused by the<br>
old distribution's version of sane. Please check your sane backends<br>
directory (/usr/lib(64)/sane) for any sane_pixma.so.0.1.24 leftovers,<br>
including the sane_pixma.so and sane_pixma_so.1 links. Remove these and<br>
re-install the backend from the source tree and you should be ok.<br>
