No idea, of course, at what step the film was scratched. After a couple of minutes of inactivity the IA-20 automatically retracts the film into the cartridge for safety. The SF-200 mounted slide feeder is almost as large as the scanner itself, adding probably half again to the length of the scanner when inserted into the scanner. The SF-200 is made to accommodate slide mounts from 1 to 2.5 mm thick, and will hold 50 in standard 1.5mm cardboard mounts. A notched plate retracts to slide the next image forward to the scanning position, after returning the previous slide to the output tray.
Finished slides are in reverse sequence.
You either take the automatic results for the entire stack or start clicking the Eject Slide button to eject the previous slide and advance the next, wait for a few seconds, click the Preview button, correct the cropping or rotation, and click the Scan button. This would eliminate two out of three steps in each scan. To change slides required 16 seconds, the Preview of each took 62 seconds, and the ICE scan took 72 seconds. I probably could have gotten this under three hours if I had stayed right at the keyboard the entire time. On the other hand, this could have been done in batch mode on the Umax PowerLook III 12 slides at a time in about two hours, with half-hour stretches away from the system, although with a slightly lower resolution.
