Check 1: Restart the computer, reduce the output resolution in ScanGear (scanner driver) and scan again.
Check 2: Delete unnecessary files to obtain sufficient free hard disk space, then scan again.
Error message may appear if there is not enough hard disk space to scan and save, when the image size is too large (such as when scanning a large document at high resolution.)
Check 3: For Location of Temporary Files in MP Navigator EX, specify a folder on a drive with sufficient free space.
Check 4: Multiple devices may be connected to USB ports.
Disconnect other devices.
