Mounting the Scan Object

Choose the object to be scanned, then mount the scan object.

The table rotates during scanning. Using double-sided tape, clay, or the like, fasten the object in place securely so that it

will not fall over or slip. Any slipping of the object makes correct scanning impossible.

When the object to be scanned has areas with cavities or voids, mounting the object at an orientation that allows the laser

beam to pass through the cavities, as shown in the figure, makes scanning easier.

2-2 Mounting the Scan Object

Effective Sensor Area
The figure at right shows the area in which the machine's sensors
detect the reflection of the laser beam, allowing the object to be
scanned.
The surfaces that reflect laser light as the table rotates and the ob-
ject passes through this area can be scanned.
When scanning an object that is considerably uneven, or that is
crank-shaped, you may need to take this effective sensor area into
account.
If the object is mounted at the edge of the table, it may not be
possible to scan the entire object correctly.
In the case of the apple shown at right, the area enclosed by the
shaded portion is not scanned.
