A Flat Mounting Plate is also available. By attaching this plate to the bottom
of your scan head, you can position the swivel mounting ball close to the
base of the scan head. Make sure the Allen nut on the mounting ball is tight.
You may also use the Flat Mounting Plate when you want to mount the scan
head with brackets of your own design. Whenever possible, mount the
scanner on its wide side as shown on page 4–3. The dimensions are shown
in Figure 4.3.
