Just got into medium format and previously scanned my 35mm negs on my Canon
5000 no problems. This particular scanner however does not hold 6x4.5 negs
so as an experiment I cut a neg down to 35mm size and scanned as usual. This
film was also C41 processed. It a nutshell everything appeared very blue and
only with a lot of correction was it resolved. I used fuji NPH400. Is there
any explanation for this as I am now somewhat reluctant to go and purchase
an epson scanner with medium format facility. Do more sophisticated scanners
identify the type of film used?

It takes a little practice and experience
to scan negatives. Quite often the scanner
driver gets in the way. The drivers on the
low end models (eg the Epson flatbed that
you might be thinking of) leave much to be
desired.

One option is to check out VueScan by
Ed Hamrick, which lots of folks swear by.
Another is Silverfast. Both of these
have been adapted to dozens of popular
scanners. VueScan is cheap, klunky, and
very powerful. Silverfast is more
expensive but with a much prettier user-
interface than VueScan.

With a decent scanner driver, one simple
approach is to scan negatives as positives
and invert in the scanner driver. Dane Kosaka
shows how it's done with NikonScan:

Personally, I've been scanning color negative
film for years, and never had any use for
film-specific "profiles".

Specific suggestion with regard to your "blue
scan" problem on your Canon 5000: try turning
off auto exposure and adjusting the histogram
manually.
