How are we supposed to know?  What did you do?  What did you expect to
happen?  What happened?

Please provide details.  We weren't shoulder-surfing at your place when
this happened and we have neither extra-sensory perception capabilities
nor crystal balls.

The dll backend not being able to load a backend should not prevent
saned from detect locally connected devices at large.  Looks like you
expect to find a device supported by the pixma backend.  If that's the
case, you may safely remove/purge any imagescan package that you seem to
have picked up from who knows where (EPSON's download site, perhaps?).

Hope this helps,
