Epson PERFECTION V600 PHOTO - Manual (Page 43)

Epson Scan previews each image, detects which type of original it is, and selects the scan settings automatically.
After a moment, you see a small preview of each image in the Epson Scan window.
Note:
It takes a few minutes to scan a full film strip.
If you need to change any settings, click Pause. You will return to the Epson Scan Full Auto Mode
window.
If you need to cancel scanning, click Cancel when it appears.
What happens next depends on how you started your scan. See Finishing the Scan for instructions.
