Cannot view TIF thumbnail in Win Explorer with Ep 4870 &

[jam2000ws6]

I have an Epson Perfection 4870 scanner and Silverfast Ai version 6.4.2r2. I had no problems when using SE Plus. With Ai, when I scan a black & white photo print at 1200 dpi with 16>8 bit grayscale, the scanned TIF image appears fine in Silverfast, but when I go to Windows Explorer, the thumbnail is completely gray with no perceptible image. If I open the file in Photoshop 7, it is fine. If I scan the same photo and save in jpg, the thumbnail in Windows Explorer is ok. It's only when I save to TIF that I get a completely grayed out thumbnail. I also get a MS message saying "Microsoft Office Document Imaging does not support this type of TIFF file". I am using Windows XP Pro. Again, I did not have this problem when using SE Plus. Anyone have any ideas?

Dear jam2000ws6

please try if deactivating HiRePP (> Options > Special) does produce TIFFs that don't show that problem.

Dear Sonny,
I de-activated (unchecked) the HiRePP option and it did not make any difference. The problem is still not resolved as the Windows Explorer view is just a gray surface with no image.

Dear jam2000ws6

I take it that you'd rescanned the images (with deactivated HiRePP)?
Sorry to ask, just wanted to make sure. Thanks for your kind understanding

Dear Sonny,
Yes, I re-scanned a half dozen images AFTER disabling HiRePP with the same result as before, a completely grayed-out image in Windows Explorer. The image looks good in Silverfast Ai6 and in Photoshop 7, but no discernable image shows in Windows Explorer thumbnail view.

Hope you can help,
