Dear friends,
How do you manage to scan 120 with this flatbed scanner, even usig the holder the film still mantain less or more slight barrel longitudinal curvature no matter how tight I try to mount it there, after developing the film I always store it inside of dozen magazines(WDCM:) ) to keep it flat,I never curl it.
This leads to obtain soft edges/corners of the scanned image .
Then I tried to scan it on Film Area Guide using a piece of glass above to hold it perfectly flat ,I've received amazingly sharp image but Newton rigs as well.
What Epson had thought of this?...

I've never had any trouble with my 4990 which was the V700's predecessor. I've scanned from 35mm to 5x4 with everything in between. There is a degree of depth of field with flat beds. Have you tried manually focusing it?

Manual focus on this scanner?!This puzzels me.. How could be this possible? I use Epson Software Scan, (I didn't like Silver Fast;perhaps wich one delivers better results?) and there's no focus feature or something like this.
Please tell me more. Whatever, the image scanned by holders looks softer overall than scanned straight on the scanner's glass ,should I remove those spacers out of the holder? there was no book/manual in the box to explain,only the electronic one wich is hard to scroll it for some particular issue.
After a couple of days I've encontered something strange, the Preview window wich normaly floats on the right side doesn't appear anymore no matter how many times I've removed and added the software into computer, I've tried any button or feature to release it back,absolutely with no succes.
I now use another computer to do the job..

You can adjust the focus by adjusting for the optimum carrier height using the small removable plastic inserts in the underside of each film holder (apparently).

Also, don't forget that the V7xx have two lenses and each one focuses at a different point. When you switch between film with film holder and film with film area guide via the software, that is how you are switching lenses.

That's true but I thought the second lens was for 6,400dpi.
To amplify on the spacers each holder has a 3 way height adjustment (of which no mention is made in the documentation!) giving a film height adjustment of 2.5, 3.0 or 3.5mm to allow for film curling and fine adjustment of the scanning focus. (Acknoledgement to Stock Agency Forum which suggests that 3.5mm is best for medium format to allow for curling).

"That's true but I thought the second lens was for 6,400dpi."
That's what I know as well.
Whatever, even switching the spacers in all positions I don't receive the sharpness of scaning straight on the glass (Film Area Guide though I don't use that thinny sqare thing,I find it useless as long as it doesn't keep the film flat and the scanner works without it)
I'm going to build a frame square shaped made of tough sponge having the ticknes exactly to fit the space between the two bodies of the scanner just to keep gently the photo frame flat on the glass.
I will tell you the results !

>>That's true but I thought the second lens was for 6,400dpi.<<
You are not limited to only 6400 ppi with this lens. This is a myth that was created by bad press kits from Epson and then perpetuated by reviewers who never really tested the scanner. Choose whatever ppi you want from the dropdown box in the software.
>>Whatever, even switching the spacers in all positions I don't receive the sharpness of scaning straight on the glass (Film Area Guide<<
This is the problem I was referring to. If you use film area guide as the setting, of course a scan off the glass is going to be sharper. That lens focuses at the glass. Therefore, when you scan in the holder that is 3 mm off the glass, it will be out of focus. When scanning with film in the holder, you MUST use the film with film holder setting so that it uses the lens that focuses around 3 mm.
>>Acknoledgement to Stock Agency Forum which suggests that 3.5mm is best for medium format to allow for curling<<
That is valid information for the original poster's scanner but cannot be taken to be correct for all v7xx scanners. There is variation from scanner unit to scanner unit. That is why they offer the three different position choices. Therefore, each person must test their particular unit to see which is best for that unit. The reality is that some units actually focus at less than 2.5 mm and some more than 3.5 mm. Additionally, if you don't keep the film flat you will only have a portion of the film in optimal focus and the other areas will be less in focus.

I've been having a right pain in the bum with my v750 today... its no wonder I didnt use it for ages. 
Managed to get some scans though. I did have a fiddle again with my holder height and compared scans, though the biggest issue is the dust. I have to do this in the bedroom and its getting quite dusty, so out came the blower and the lens cloth.
It has made me wonder if theres any decent professional film scanning services that I could afford for specific negs and trannies. Peak are just too expensive - it'll be near to £100 for 10 scans.

A couple of sites for you to look at:
here
and
here
I have used the first one but not the second one.
Hope this helps you decide.

Apart from the problems mentioned here just how good are the Epson V7xx scanners in terms of scanning quality - In other words would a 120 scan produce a good enough digital image for stock libraries? 
Does anyone have experience of the Epson v500 ?????

The v7xx scanners do scan a lot of detail if you're heading down the 6x6 and higher route. 645 would scan ok for alamy too I'd reckon, though you'd need a quality lens for the image first. For 5x4 its perfect. The 700 will do pretty much what the 750 does, it just doesnt come with the extra bobbins iirc. You can wetscan on both - something I've not tried.
I'm afraid I know nothing of their v500 but if it uses the same sensor mechanics and similar software it could be good enough for medium format. Ask on a few stock agency forums if they use them and their views to be sure though.
