Hi There

2.Was it working fine earlier?
3.Were there any recent changes made on the computer prior to the issue?
You may receive this error if you don't have the appropriate permissions to use the scanner.
Let's try these methods and check if it helps.
Method 1: Install ScanSnap Manager Update (S1500) and check.

I had this exact same problem. Turned out that I was using the wrong power adapter. Enough power to turn on the scanner lights and connect to the computer, but not enough to actually perform a scan. As soon as I realized I was using the wrong power cord, I switched it up and voila!

You need to open up the unit and clean all pieces of glass. There is something on the glass causing the line.

Go to msconfig or if you have a registry cleaner, go to the startup menu. Disable and ssmgr (scansnap manager in pfu). Reboot. Open the ScanSnap 1500 and then start the ScanSnap manager. The scanner is now ready to scan.

I got off the phone with Fujitsu and i was told you need to make sure that the ScanSnap Icon is in the system tray without a Red Line cross through it, so if it is not in your system tray start the snap scan program, if it's disabled re-enable it and you should be good.

Find your specific scansnap product and update it:

A user had a similar issue and I found this update for the scansnap S1500 manager:

This occurs with certain Intel dual core processors, so you might be effected accordingly.
