Your 9420 OneTouch scanner is specially designed to scan 35mm slides
and negatives. You can scan both positive and negative film images.
A B RIEF E XPLANATION
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 lid. When you scan a 35mm
slide or negative, the light in the bottom of the scanner turns off, and
the light in the lid shines down through the film onto the sensors to
capture the film’s image.
