Laser Warning
WARNING: Class II Laser product. Avoid long-term viewing of
direct laser radiation. Prolonged staring into the beam (direct or
reflected) can damage the retina.
This system uses a class II laser which is considered eye and skin safe but can cause eye
damage if exposed directly for a extended time. Natural human reflexes will normally
make the subject blink or look away before any damage is inflicted to the eyes. Any use
other than those specified in this document could result in hazardous laser radiation
exposure.
Use the following usage precautions:
•Never stare into the beam, neither directly nor from a mirror-like surface. Human
skin is not considered as a reflective surface.
•MEDICAL USAGE: warn subjects not to stare into the beam. Subjects under
effect of any medication and young children could possibly have their
natural aversion reflex affected and it may be advised to wear a
blindfold.
•The ZScanner 800 should NEVER be opened for any reason as there are no
internal adjustments. In case of a malfunction, contact the manufacturer or
distributor.
CAUTION NOTES
PLEASE READ THE COMPLETE MANUAL BEFORE USE. OPERATING YOUR ZScanner 800 LASER
SCANNER USING PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.
AVOID DIRECT EYE CONTACT WITH THE LASER BEAM.
ELECTROSTATIC DISCHARGES COULD DISCONNECT THE DEVICE.
DISREGARDING ANY OF THE RULES AND CARE RECOMMENDATION INCLUDED IN THIS
MANUAL MAY VOID THE SYSTEM WARRANTY.
Please read and follow all WARNING statements throughout this manual

Scanner General Care
The ZScanner 800 contains optical precision parts and must be handled with care to
avoid damage to the components or the calibration system. For transportation, the
system must be placed in the carry-on case provided with the kit. The system must be
stored in a dry, dust-free place and kept at room temperature.
The scanner must be kept on its support or in its carrying case when not used.

Clean the interference filters with a clean and dry cloth. The ideal is a lens or glasses
cleaning-cloth.
Never open any of the system’s components. By doing so, the
user may inadvertently damage the system and the ZScanner
800 will have to be recalibrated. Only ZCorp staff or authorized
technicians are qualified to work on the scanner. No
maintenance is required by the end user. If the system shows
any troubles or malfunctions, it must be sent back to ZCorp or to
an authorized reseller.
Unauthorized manipulations on the scanner will void the
warranty.
Software Presentation
Positioning Features
In order to position itself in space, the ZScanner 800
creates a positioning model from the positioning targets.
At all times, the scanner needs to be able to see at least 4
positioning features. These features are the positioning
targets that were placed either on or around the object
before scanning.
There are two different ways to acquire these targets:
either by using the Scan Features mode or by detecting
features interactively in the Scan Surface mode. The
former enables the acquisition of the targets only, while
the latter concurrently acquires the targets and the surface of the object. The resulting
model, whether it has been acquired in Scan Surface or Scan Features mode, can then
be exported for later use.
During scanning, if a target is detected more than once, the ZScanner 800 will update
the position of the target with the new detected position, therefore increasing the
precision of the positioning model during the scan. The user can also choose to activate
or deactivate the use of a positioning feature in the positioning model in order to
exclude that target from the calculation of the sensor's position or orientation.
References
To represent the space in which the object is positioned,
the scanner needs a 3D coordinate system. By default, 3D
data is represented in the "Sensor Reference Frame",
whose origin is set to be the scanner's position when the
user starts to scan.
