Thanks for the tip, but it still doesn't work:

desktop /tmp $ scanimage -L
device `pixma:04A91913' is a CANON CanoScan LiDE 300 multi-function peripheral

desktop /tmp $ scanimage --device=pixma > image.pnm
Output format is not set, using pnm as a default.
scanimage: open of device pixma failed: Device busy

I'm wondering if it could be some problem with USB. But then, it worked fine 
until that scanner lamp broke...

Cheers,
Volker
