I've been mucking around with some black perspex and a milling machine, trying to make a 7x17 film holder for a V700.

The idea is to be able to use the "Super High Res" lens on the scanner, rather than the lower res used when using the Film Area Guide. The images will then be stitched.

The holder has an opening roughly the same area as the scanning area, with a milled area overhanging the end of the scanner that supports the film. After the first scan, the film is then turned around for the other end to be scanned.

Anyway, I hope you get the idea.

The trouble is that I cannot seem to get the scanner to run a scan. It works fine with the Film Area Guide, but not with the holder. (And now my Betterscan holder won't work).

So, can anyone tell me if there is some kind of "kill switch" when using bigger images that prevents scanning? If so, can it be overridden?

I have tried both Epsonscan and Silverfast with no luck.

Thanks.
