The magnification of an image can be changed before scanning to accommodate
reproductions that are larger or smaller than the original. The settings can be changed in
increments of 1%. While the size of an image can be changed through other means,
enlarging an image during the scanning process can save time by eliminating
unnecessary steps.
Changing the magnification setting causes the resolution display on the control panel to
change correspondingly. This resolution setting is referred to as the “scanning resolution.”

Hint
Magnification and Resolution
Why does the image size change with the magnification? Let us answer this
with an example using an “BJ (360 dpi)” output device. If you were to scan an
image with this device setting and set the magnification factor to 50%, the
scanning resolution will automatically change to 180 dpi. At this setting, the
image will be scanned at a resolution of 180 dpi and the output device will
convert this to 360 dpi, shrinking the size of the output in the process because it
will only have half the data with which to fill the space.
