When scanning slides, the scanner crops the top and bottom of the picture. why is this?

Be sure to put the slide in the holder in the proper direction. The opening in the slide holder is rectangular, not square like the slide. If you place the slide in the holder horizontally and the holder window is vertical, it will crop off the sides of your picture.

I am having exactly the same problem. Any solution yet?

Hi I'm having a similar problem and haven't managed to fix it. Have you solved it? Thanks Martin

Your scanner came with some software inside the box. If this is a second hand scanner with no additional software download the drivers from www.canon.com and run the software accordingly.
Mac os X does not require this process. connect the scanner to your machine and simply load the slides in the tray scanner and use the application "IMAGE CAPTURE" located in local_disk/applications/
The pictures automatically load and you select to crop or scan as is.
Later the image will appear on the desktop upon completion of scan.

If you are using epson scan to scan from your computer, please uncheck the thumbnail option.

Uncheck the option that says "Thumbnail" and draw individual marquees for the area on the slide you want to scan. Not very elegant but it works.

I don't know if this is truly a "solution" or not, but I get the same thing on my HP 4850 scans. After scanning, I just crop the pictures to remove the black borders. Can you do that?

For unexplainable reasons, the Software seems to set it self to a crop of 17x1 pixels. Therefore, the files are small and the pictures essentially a small line. A reset of settings to factory defaults corrects this.
