FARE will ABSOLUTELY not work with Kodachrome slide or any B/W film/slides (this is note in their documentation).

It is possible there are some other film/slide types that cause the same result.

For what it's worth the one time I've called Canon customer service I recieved excellent support....

: For some reason, the FARE dust removal feature won't work on my FS4000US. Whenever I try to run it, either I get a message half way through the first scan that FARE has failed, or the scan finishes but no dust removal has taken place.

: I've tried calling Canon customer service, but their web site only seems to bounce me to a service site for the Powershot digital cameras. I finally succeeded in reaching a phone number for scanner technical support; however three different CSR's either passed me off to someone else (who didn't know what to do about the problem or insisted that I needed to call (at my expense) another number.

: My questions: (1) does anybody out there have any idea what's causing this problem; and is there something I can do at home to fix it; and (2) has anyone else had this kind of poor service from Canon USA? Since I've owned Nikons since 1980, I've never had to contact Canon service previously; but I must say I've never worked with a worse tech support department. Does anyone have a number for getting through to someone who actually answers questions, instead of saying "we don't have anything to do with that here"?
