Note
- Turning the brightness dial affects the scanned image in a similar manner as a change of brightness in
the projected microfilm image. For this reason, the foregoing image sequence also demonstrates what
happens if the brightness of the projected image changes while the brightness setting remains
unchanged.
- With scan mode "Normal" the quality of the print-out depends strongly on the brightness setting. For
brightness set at 0 the image may be completely white, for brightness set at 20 the image may be
completely black.

Border Elimination
When scanning an image, it is possible that different reduction or magnification factors during the filming
or projection onto the viewing screen of the microfilm reader cause the original page not to coincide exactly
with the ScreenScan™ scan area on the viewing screen. If the image is smaller than the scanned area,
black borders may result. These black borders cause excessive use of toner during print-out and should,
therefore, be avoided.
ScreenScan™ provides a way to eliminate, or at least to reduce these black borders by selecting the
“Masked” Scan Mode.
Note that for obtaining the images in the following figures only the scan mode was varied. All other settings
were identical.
