I'll be mid-way through scanning negatives, then after a while (maybe an hour) the software will just quit on me when I hit the 'Preview' button, and then after restarting, refuses to select 'Film' mode. My V500 has developed this problem recently. ) obstructing the initial sensor area (middle section near hinge)? Which film holders have you been trying? Placed correctly on scanner and nothing (dirt, Film. You are removing the document mat? And unlocking the transportation lock? How did you install the scanner when changing over computers? Scanner first and then software install? If so try the other way round (after removing all software). Similar for Professional and Home modes (change document type). Which mode are you using? If Full Auto Mode then try 'Customize' and change to film mode. The only thing that comes to mind is perhaps the computer thinks its a model that doesn't have a transparency adaptor. Is the transparency adaptor plugged in on the back? I never had this problem on my old computer. i installed the software and drivers, but when i go to scan negatives the software wont let me select the 'film' option.only the 'reflective' option.

So i've had the v500 for awhile now, but recently got a new computer.
