background suppression value is set so large that areas of medium density appear extremely
light.
Figure 10 Light Background in Copies of Originals with Frames
Cause
[Auto] performs background detection of images at a distance of up to 10mm from the Lead
Registration Edge. If there are dark frames along the Lead Registration Edge, Automatic Expo
-
sure cannot detect the original background density. Therefore, Background Suppression is cal-
culated based on the density of the frames.
