22 VISIONEER ONETOUCH 9220 USB SCANNER INSTALLATION GUIDE
SCANNING 35MM SLIDES AND NEGATIVES
Your 9220 OneTouch scanner is specially designed to scan 35mm slides
and negatives. You can scan both positive and negative film 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 35mm slide or negative is on the glass, however, the light
from the bottom of the scanner would shine up through the transparent
35mm slide or negative 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 35mm slide or negative, the light in the bottom of the scanner
turns off, and the light in the cover shines down through the film onto
the sensors to capture the film’s image.
To prepare to scan a 35mm slide or negative:
1. Place the transparency mask on the scanner glass, positioned as
shown in the following figure.
