I guess most of the V700/V750 users have newton problem when scanning 8x10 film.
I hate to see it and decided to find the solution - remove the glass and custom make a mount for 8x10 film. (As most of my works are 8x10 film, i.e. my solution is for 8x10 film only)

1) First, we have to remove the screw cover (four of them) from the top cover. You can use strong tape to remove it. It doesn't damage the cover, i.e. Epson won't know that you had removed the cover!!!



2) After that, remove the screw underneath and take out the top cover.



3) There are 6 clips that hold the glass, remove them all.



4) Next, we need to remove the glass from the strong tape. Use lighter fuel and soften the tap, it takes some time!! (You can always use your hammer, if you are in hurry! LOL!)
