    7x17 film holder on Epson V700 - not working...

    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.
    Lachlan.

    Lachlan, I also have a home built holder and cannot get a scan with it using the higher resolution lens on my V750. I have a hunch that the preview shows the scanner that the file is too big to handle. Dunno. I've abandoned the attempt for now.

    If you look at the hinge end of the factory film holder you'll see a group of small triangular holes centered near the edge.

    This is a binary code that the scanner reads to know which holder is in place and the number, size, and location of the originals.

    Without a code for 7x17 in your holder at the correct location, you're not going to make it work regardless of how hard you try.

    You could contact Epson to see if such a code exists, but I rather doubt it.

    Very interesting, Leigh, and also very helpful, I hope. Many thanks for letting me know.

    I might try to copy the 4x5 holes and see if they allow me to scan a wider area of the glass. Nothing to lose...

    You might ask if they have a code for "User Defined" or "Custom".

    That would give the best chance of success for what you want to do, if the scanner and software will support it.

    Re: 7x17 film holder on Epson V700 - not working...

    I assume your using the 8x10 area of the glass if your scanning 7x17 inch, the film guide for that area has no coding hole just a 12mm space at the back for setting the white balance that needs to be kept clear. If you base your scanner holder on that it should be OK.

    Soory just read yopur trying to use the hi rez area, I think thats limited to 5in wide

    I thought you meant 7cm x 17cm, not 7" x 17". It does help to specify.

    You can't do 7" width at high res. You might try turning it 90░ and doing it in three scans roughly 5.7" x 7".

    The active area for high res is something over 5" wide, but I can't find the spec.

    The 35mm mounted slide holder, which works in high res, has an active area of 5.5" x 8.5", so it will scan at least that large an area.

    You will still have the problem of identifying the format to the scanner.

    Given 7x17 is a well recognised format, and that I wrote the following, I didn't think that I needed to specify in inches.

    "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".

    Sorry for the confusion.

    Perhaps it is, but I've never heard of it.

    Pardon me for trying to help. I shan't make that mistake again.
