I had the problem with my 750, too. I found a comment online blaming the scanner software. I solved it by using the wet scanning holder, putting a piece of anti-glare picture frame glass on top, and scanning dry.

Note that I communicated directly with Epson about the problem and they admitted there was a software issue that caused this effect under specific circumstances. It's not speculation, or rumor - Epson expressed this to me directly. I have the official PDF document Epson sent me that describes the issue, which I have attached a copy of.
I carefully louped two rolls of TriX 120 from this shoot and I can barely make out slightly lighter bands along the left side of several negatives. In fact, they were done with two different plastic reels, one 30 years old and one only ten or so years old. Thanks for your suggestion about the cause of the artifact. It looks unavoidable, but with some attention in Photoshop I can edit it out.

Strange!
I mostly scan with the Epson's wet scanning holder, wet ofcourse, and with an acetate foil over the whole lot of two negative strips of three 6x6 negatives, and still see these bands showing up.
But I will try Simmons's method next time.
PS: I wonder why they couldn't solve that "software fault"...
I use Vuescan and saw the problem, so I don't think its Epson scan that's the problem. Is there software in the scanner itself?
One can only imagine what's going on between the scanner and the receiving end (computer). Thinking about it, it's easy to figure that there's probably some programmed chips n the scanner that capture the signal and turn it into something that the computer software can read and interpret. Wouldn't be surprised if this were a practical concern, being as raw luminance signal data could be just too big to send and keep the scanner scanning at the same time.
Meanwhile, it's probably a good idea to have some blank film at the end that starts the scan. Or, try leaving a little space at the end before the start of the image.
I've never used the V750, but plenty of other scanners I have used have a blank calibration area, and they warn you not to let the film intrude into that area.
I was scanning single sheets of 4x5 so there was no intrusion into the calibration area. The internet post I found said that light bends around the film edge and is picked up by the scanner causing the dark line. Who knows what the truth is?
