I'm starting to think something is wrong with the unit. But it did work fine out of the box. The scanner and software has been updated entirely with no USB connection issues whatsoever. I've cleaned and optimized the card for use thru my card readers on 3 newer windows 10 computers. I D/L from scratch the ezscan software on my last windows laptop. This time though, I didn't import one of my archives. I started fresh with the tedious job of building a whole new file/archive and settings with new scanlists. Then, I put the card back in the scanner, it initialized properly and fired up like a champ and hummed along until I pressed the menu button again to changed a couple settings. However this time it had a new present for me. The screen showed scanning "scan-list 001" ONLY when in actuality, I have 5 to 7 named scan-list's scanning at any given time. Then I hit the menu button again and it went back to the same error code and pretty much shut down on its own. I pulled the card and looked it over in ezscan and nothing was changed on the software or anything to show "scanlist 001" I think its possessed ! Its troubling because all I have to do to get it scanning properly again is to shut it off, wait, and turn it back on. I guess its ok as long as I don't have to use the menu keys, but not for a brand new $600 scanner. It should work properly. I'll keep plugging along and watch for any suggestions before it goes back. I was thinking about getting another SD card and trying that as long as that is permissible with this type scanner and only able use a proprietary card from Whistler. Thanks again for your help, very much appreciated !!
