You can scan all sorts of transparencies with your 8820 OneTouch
scanner, including 35mm film strips and slides, large format (4" by 5")
film, and presentation slides (5" by 7") typically used with overhead
projectors. When scanning film strips and slides, you can scan both
positive film and negative images.

Your scanner has sensors that capture the image of the item being
scanned. Those sensors are located in the body of the scanner. When
you scan a paper item, the light in the bottom of the scanner shines up
on the paper and reflects the paper’s image down onto the scanning
sensors. If a transparency is on the glass, however, the light from the
bottom of the scanner would shine through the transparency and would
not reflect its image onto the sensors. That is why your scanner has a
light in its document cover. When you scan a transparency, the light in
the bottom of the scanner turns off, and the light in the cover shines
down through the transparency onto the sensors to capture the
transparency’s image.
To position a transparency for scanning:
1. Unsnap and remove the pressure plate from the document cover.
The pressure plate protects the transparency light source in the
document cover.
