SCANNING TRANSPARENCIES
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.
A BRIEF EXPLANATION
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.
