Scan problem

We (a not-for-profit historical rail history society) use an Epson V850 Pro scanner, and it has developed a strange problem when scanning color photos.
About 3 inches in from the right side (of the scanner), all scans will have a bright red vertical continuous line, maybe 5-6 pixels wide (at 1200 DPI). It is highly noticeable in dark areas of photos, but just about disappears in brightly-lit areas in the very same photo. My first thought was dirt, but that might show up in all areas as a dark line. And because it is more than one pixel wide, that likely eliminates a dead illuminating pixel/LED.
If I offset a small photo to stay away from the fault, there is no problem. However, limiting scans to objects under 5 inches IS a problem. I haven't checked it with slides or large-format negatives yet, but suspect the problem will not just disappear.
Epson ignores my requests.
Any thoughts?
Thanks for the help!

My first thought is that a company with a reputation for quality products and owned by electronics giant, Seiko, should be making an effort to help solve their customers' problems. (I've been an Epson user - scanners and printers - for years and am distressed to hear of their lack of concern for their customers.)

I had a similar experience with a Canon scanner a couple years ago. I had run a sheet through the feeder that had a dab of wet ink, which transferred to the roller and showed up as a streak on every scan afterwards. My repair required some disassembly of the feeder and any other surface including glass to remove the stain. If the streak runs the entire length, I would suspect a glass area? Do you use a feeder or individual on the platen? Have you tried both to see if the problem is confined to one method but not the other?

Have you tried contacting them via their website? Epson is usually responsive if you reach the right person. Don’t give up on them.
That said...
Unless scanning negatives, and EVEN then, I’d buy a decent copy stand and soft boxes, a digital camera with 1:1 capable macro lens, and a backlit source of continuous spectrum light for film.
Capture is much faster, and raw camera files can be corrected better. You will need to do more spotting, unless you clean the art first. (The key advantage of the scanner is Digital ICE.)

I, too, have found Epson less than helpful regarding the V850. I think most of their techies don't know it exists! I've had lots of difficulties with mine, but none like you describe. Questions: Is this when scanning negs or pictures? Have you cleaned the surfaces? (I found mine were REALLY dusty and that was contributing to the dust on the resulting scans that I had to clean up!)

I have read that sometimes dust will settle on the imaging sensor and the best "home" remedy can be to hold the scanner on its side and perform a scan in the hope that the dust falls off of the sensor. This seems like a low risk procedure.

It is the website that is not responding. There seems to be a dearth of info on how to contact a real person.

Not so sure. It is a traveling sensor, so the problem has to be on the scanner's sensor / light source unit. Opening that glass gives me the willies.

Nice idea. I'm not sure how to apply it to this unit, but it holds promise.

The red "line" shows up only when scanning photos that have a dark area in them. In white areas, the line disappears. There is a clue or story in there somewhere, but I'm not grasping it.
