3. Open the scanner’s book cradle completely, as shown on the screen.
Note:

After the Autofocus function has completed, the results will be displayed. Values displayed
in green indicate valid results. Any error will be shown in red text, followed by some
explanatory remarks.
Note:
It is normal that the measurement will return different values each time the
measurement is repeated. The lens motor has a very high resolution and the
best focal point has to be found in the already large focal range, therefore a
variation of 50 – 100 in values is normal.
