General care
The ZScanner 700 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 ambient
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.
Never open any of the system’s components. By doing so, the user may
inadvertently damage the system and the ZScanner 700 will have to be
recalibrated. Only Z Corporation staff or authorized technicians are qualified to
work on the scanner. No maintenance is required by the end user. If the system
shows troubles or dysfunctions, it must be sent to Z Corporation or to an
authorized reseller.
Scanner Manipulation
The first step when it comes to scanning with the ZScanner 700 is to be able to
connect the system properly. Also, in order to avoid recalibration, the ZScanner
700 should always be properly stored in its case.
7
Connecting the scanner
The first step is to turn on the computer.
Safely place the ZScanner 700 on its stand.
Figure 1.2 Position of the ZScanner 700 on the support
Next, the FireWire adapter should be plugged into the computer with the cables
plugged in. The connections are shown on the pictures below:
Figure 1.3 Scanner's connection on the computer
The outlet end of the power supply cable should be plugged into a power outlet
using the appropriate outlet adapter. The end of the FireWire cable with the rightangle 6-pin plug should be plugged into the ZScanner 700.
Launch ZScan.
8
Storing your ZScanner 700
First of all, the calibration plate should be stored at the bottom of the case,
underneath the foam. The calibration plate is a fragile piece of equipment and
must be handled with care. It should only be taken out of its case at the time of
use. The targets used on that plate are not the usual targets. It is important to
avoid touching them with your fingers since human skin fats could affect the
reflectivity.
Figure 1.5 Scanner's calibration plate location
Next, after putting the foam back in place, every item should be stored properly
into its specific location:

Concept
The ZScanner 700 was designed to allow easier and faster digitization. With its
easy to use interface, this system does not require any specific knowledge of the
laser-digitizing field. Its principle is based on the alignment of 3D curves of the
part scanned. The surface created will then generate a model that will be
exported for treatment.

General Concepts
File Types
.CLF
CLF is the license that makes ZScan functional. A specific license is required for
each ZScanner 700 sensor.
.CST
CST file contains configuration data unique to each ZScanner 700 sensor. The
file includes calibration parameters and information needed to create a new
session.
.CSF
CSF file contains all the data related to a previously saved session such as the
scans, the resolution parameters, the deleted facets, etc.
.STL
STL files are used to export facets. This format can be read or processed by
most post-treatment software.
.TXT
TXT files are used to save data in ASCII files. The positioning model containing
all the positioning features is saved under this format.
.OBC
.OBC files are used to import photogrammetry positioning models acquired with
AICON 3D Systems software.
Positioning Features
To position itself in space, the ZScanner 700 sensor uses a positioning model
which is a combination of many positioning features. These correspond to the
positioning targets that were affixed on the object before scanning. The
positioning model can be built before scanning the surface. To do so, select the
“Scan Features” mode in the software. It can also be built during data acquisition
by selecting the “Scan Surface” mode. While scanning, every positioning targets
acquired by the ZScanner 700 will be added to the positioning model. Each
positioning targets can be activated, deactivated or deleted from the positioning
model. Note that a deactivated positioning target is no longer included in the
calculation of the sensor position or orientation.
19
References
To draw a surface in STL format, the system uses many small triangles. Each
triangle is formed by 3 vertices represented in a 3D coordinate system. By
default, 3D data are represented in the “sensor reference frame” which is
determined from the first sensor position and orientation when you start scanning.
You can change the coordinate system either automatically with the “autodetected” reference model, or manually by creating another reference with the
Reference Building tool. Detailed explanations on how to use this tool will be
provided in following sections of this User Guide.
Each reference available in the selected scan can be renamed, deleted or set to
be used as the origin of a new reference frame.
Surface and Volume
The Scanning Volume Bounding box can be resized, moved or rotated. The
Surface Resolution can also be adjusted according to the level of details you
need. Detailed explanations on how to do this will be provided following sections
of this User Guide.
Facets, Edition and Multi-resolution
The final output of the scan are the facets which make the STL file. Facets
are composed of many triangles. Before saving facets in an STL file, they can
be edited to remove some unwanted surfaces, patches or to change the
resolution of some parts of the object.
For example, you may want to get a higher resolution on a specific detail of the
surface to accentuate its edges. You may also wish to remove an unwanted part
of the surface by deleting it.
Deleted facets are moved into the recycle bin and can be restored at a later time.

Sensor Configuration
This tool is used to configure sensor’s laser power and the cameras shutter time
according to the type of surface you wish to scan.
31
Figure 2.23 - Sensor configuration window
To configure the sensor correctly, the parameters should be set to have a
majority of detected laser points included in the reliable zone. This step can be
done manually by moving the sliders at the bottom of the screen or automatically
by clicking on the Auto Adjust button.
Note: In cases where there is too many under exposed points, the laser
traces are not detected correctly. On the other hand, in cases where there is
too many saturated points, the laser traces detection is not as precise.
Sensor parameters can be saved and restored later with the control buttons at
the bottom left of the screen.
32
Sensor Calibration
This tool is used to verify and optimize sensor calibration.
Figure 2.24 - Sensor calibration
To complete the optimization process, follow this procedure:
Press the Acquire button to activate the sensor
Lay the calibration plate on a stable plane surface. Position the scanner at
approximately 10 cm (4 in) from the calibration plate
Use the Preview button on the ZScanner 700 to position the laser cross in the
white cross of the calibration plate
Press the trigger and move the scanner slowly away from the plate to an
approximate distance of 60 cm (24 in) or until the 10 measurements are taken.
Make sure that the laser’s cross-hair stays in the white cross of the calibration
plate.
Follow recommendations displayed in the Sensor Diagnostic area.
In ZScan 1.3, more information is available in that window. It is now possible
to see your factory calibration date as well as last optimization date. Please note
that to be able to see your factory calibration date; your scanner must have been
calibrated after the ZScan 1.3 release date.
TIP: Press the Default button to reset the sensor calibration to its
factory settings. Use this functionality only if the optimization
process fails to give valid results.
33
Build Reference
This tool is used to manually build a new reference that could be used as the
origin of the new reference frame for the facets.
Figure 2.25 - Build reference window
You can choose between 5 building modes:





Duplicate Reference:
Create a new reference from an
existing one.
3 Planes:
Create a reference by specifying
positioning features from 3 planes that
will define the axes of the coordinate
system.
1 Plane, 1 Line, 1 Point: Create a reference by specifying
positioning features on base plane, on
a reference line and a reference point.
3 Positioning targets:
Create a reference by specifying the
position of three targets.

It is essential to prepare the object prior to scanning. Reflective targets must be
affixed randomly on the object with a minimal distance of 20 mm (0.75 in)
between them. For flat surfaces or with a slight curvature, the distance between
each target can reach 100 mm (4 in). Those targets will enable the system to
position itself in space. Positioning targets must be applied on plane surfaces
keeping at least 12 mm from the edges on every side.
Here is an example of proper target distribution.
Figure 3.1 - Proper target distribution
Figure 3.2 - Improper targets distributions
35
TIP: For better digitization, any object that is shiny, black, transparent or
reflective, (mirrored, glossy or metallic surface) might need to be
covered with a white powder in order to give it a matte finish.
TIP: Proper target distribution may be difficult to obtain in some cases
such as small surfaces (small objects). It is then suggested to
distribute the targets on a plane (preferably black/dark and matte)
and place the object on this plane, often referred to as a target pad.
Reference targets
It is now possible to use special reference targets on the part to insert references
recognized automatically by ZScan. These reference targets can be bought from
your local reseller in many models to create multiple references in the same scan.
To use them, simply acquire the targets on it. When the acquisition stops, ZScan
will recognize it and automatically insert a new reference at that point. This new
reference can be used as the origin of the scan. Many of them can be used to
reference multi-scans projects. Three of them can be used to create a new
reference from known points. More information on these items is also available
from method sheets on our website via the customer portal.

Starting the Software


Connect the scanner to the system as explained in section 2.2.
To start, launch the ZScan application by clicking on the ZScan icon on the
desktop or from the start menu.
The scanner must be connected to the computer prior to
launching ZScan
TIP: You can rename the current scan from “New Scan” to the name
you want by clicking on it.
Adjusting the surface settings
In the Menu click View - Surface or click on the surface node in the tree. The
following expanding panels will be displayed.
Figure 3.4 - Surface mode expanding panel
In ZScan 1.3, you do not have to rebuild every time you change a
setting. A live preview will appear as you change parameters, click
apply or refine to apply changes.
37
Surface Details
Displays a summary of the current settings: dimensions of the volume
bounding box and the current resolution.
Surface Parameters
 Adjusts the volume of the digitizing box according to the object size.
 The resolution setting depends on the volume of the Bounding Box set
previously. However, it is possible to choose from 3 levels of resolutions:
High, Medium and Low.
 Click on Apply to confirm the setting.
More information on the Fit and Center Volume is available in the section on
Volume Functionalities on page 24 of this User Guide.
TIP: It is possible to change the settings following the completion of
the scanning. Click Apply to confirm.
38
Configuring the sensor
Configure the laser power and the cameras integration time according to the
digitizing conditions (object nature, light, color, texture...)
In the Menu, click Configure - Sensor
Figure 3.5 - Sensor configuration window
Two settings modes are possible: manual and automatic.
In manual mode, trigger towards the surface to be digitized in order to adjust the
settings of the laser power and integration time. Colors will describe the exposure
state.
Grey: underexposed
Yellow: OK
Red: overexposed
In automatic mode, click on Auto Adjust and trigger towards the surface.
Click Apply and then Ok to confirm settings.
39
TIP: Darker surfaces will need more laser power and/or longer shutter
time. However, longer shutter time will catch more noise. It is
recommended to increase laser power first and increase shutter
ti m e a fte rw a r d i f ne e de d to ca tc h ve r y da r k s ur fa c es.
The object can be moved during digitizing without altering data
acquisition as long as the reflective targets are affixed on the object.
Importing positioning targets
It is possible to import previously acquired positioning model in ZScan. From the
1.2 version, it will now be possible to import positioning features acquired by the
ZScanner 700 or by a photogrammetry system. Please note that ONLY
ZScanner 700 TARGETS CAN BE RECOGNIZED. Any other type of reflective
target will not be usable in ZScan. Files to be imported must be composed of
three columns (X Y Z) separated with a SPACE. The three columns represent
the center of the target.
Imported targets will then appear as spheres as ZScan cannot know in which
direction they are. He will use the center to recognize the patterns and add the
normal when scanning.
Acquiring data
To start the scan, click scan - Record Scan or click on
in the toolbar.
 Take the ZScanner 700 in one hand and position at about 300
mm (12 in) away from the object.
 To have the laser cross displayed on the object at any time,
press the preview button on the ZScanner 700 (see figure 1.1)
 To launch the scan, press the trigger button on the ZScanner
700 (see figure 1.1) Sweep the object surface while holding
down the trigger button.
TIP: The quality of the results will be directly influenced by the number
of times and the speed with which the surface is swept. The more you
sweep the surface, the more accurate the results will be.

Proper digitizing distance
The Distance meter
While digitizing an object, a meter displayed on the screen illustrates the distance
between the scanner and the object. This meter is also represented on the
scanner by 3 LED lights located on the top of the ZScanner 700 (red, green,
red). See pictures below for visual description.
Figure 3.6 - Graphic and physical representation of the scanner too close to the surface
Figure 3.7 - Graphic and physical representation of the scanner with a proper distance
41
Figure 3.8 - Graphic and physical representation of the scanner too far from the surface
TIP:
When the scanner is too close to or too far from the surface, it loses
tracking. This means that the cameras can no longer position the
targets or that the target distribution is improper. If tracking is lost,
reposition the scanner in front of a surface already scanned and
trigger again or try to redistribute the targets on the surface
differently.
Any dysfunction of the ZScanner 700 is identified by 2 red LEDS on
the top of the scanner.
TIP: When the scanner is too close or too far from the surface, it loses
tracking. This means that the cameras can no longer position the
targets or that the target distribution is improper. If tracking is lost,
reposition the scanner in front of a surface that has been scanned
and squeeze the trigger again, or you may need to redistribute the
targets on the surface differently.
Any dysfunction of the ZScanner 700 is identified by illumination of
the 2 red distance LEDs on the top of the scanner.
42
Editing the scan
To delete a part of the scanned object, set ZScan to Facets mode. In the Menu,
View - Facets or click on Facets in the tree. Set the Edition Mode by clicking the
Edit Facets button and choose a selection mode.
More information on the selection tools and possible operations on the facets can
be obtained in the Toolbar and Expanding Panels sections.
The deleted facets are placed in the recycle bin which can be selected in the tree
by clicking on the Recycle Bin button in the menu tree.
Figure 3.9 - Deleted facets
Saving your work
Use the “Save session” option to save your entire session for editing in ZScan.
This is the most complete save as everything can be restored later and the scan
can be continued.
Use “Save Facets” to export a file for use with post-treatment software. Only the
facets will be exported. Exportation can be done in STL files (ASCII or BINARY)
or the points (extremities of surface triangles)
Use “Save Positioning Features” to save your positioning model for later
importation. Note that imported positioning features will be static and will not
readjust their position while scanning. You will not get results from the “Optimize
Positioning Model” in this case.
TIP: It is recommended to save the STL first, then the session, then the
features.

I am experiencing slow frame rates when scanning.
I am experiencing display problems when using ZScan.
My scanner refuses to calibrate.
The "Power" LED on the scanner does not turn on even when I connect it.
I can't see the "3D Imaging Devices in Windows Device Manager.
How can I contact you if I can't find solution to my problem?
I get the following message when I start ZScan: “The scanner is
disconnected. Scan functions will be unavailable.”
There is no scanner connected to your computer or there is no valid configuration
file for this scanner installed on the computer. Make sure that your Configuration
File is installed properly (see the "No Configuration File found" help item). Once
this procedure is completed, see the Connection Troubleshooter if the problem is
still there.
I get a “No Configuration File found” message when starting ZScan.
Your configuration file is not present or corrupted. Please download a fresh copy
of your latest Configuration File and use ZScan File Manager to import it properly.
Make sure that a file name YouSensorSerialNumber.cst is present in the
following folder: \\YourZScanInstallationPath\Configuration\. Don’t hesitate to
contact us if you feel that the license on the extranet was not updated properly.
44
I receive an error message while scanning telling me that an internal error
has occurred.
There is a high probability that this error message was triggered by a connection
problem. Please see the Connection Troubleshooter.
ZScan is giving a “License Expired” message and refuses to scan.
Your ZScan license is expired. Most of our systems are shipped with 90 days
licenses by default. Use ZScan File Manager to import your new license. Make
sure that a file name YouSensorSerialNumber.clf is present in the following folder:
\\YourZScanInstallationPath\License\.
My surface doesn’t appear completely when in facets view.
The part you are scanning may be too large or not centered in the scanning
space. Make sure your scan is properly positioned using the functions available
in “Surface” view.
Some holes appear when I increase resolution.
Increasing resolution requires more data. Holes can be created if there is not
enough data to reconstruct surface at this resolution.
I checked the option to install the plug-in for Geomagic but there is nothing
under plug-in in Geomagic.
Make sure that you chose the right plug-in for your version of Geomagic and that
you can find the file ZScanGeomagic”X”PlugIn.dll where “X” should be your
version of Geomagic.
I have some problems hooking my ZScanner 700 to targets, it looses its
position
Please make sure that you use the calibration tool to optimize your calibration,
this should be done before starting to scan every time you use it.
I have some difficulties scanning more dark surfaces or parts of the
surface.
It is very important to go adjust the laser power and shutter time for each surface
that has to be scanned. Refer to section 3.3.
I am not able to scan small parts.
Smaller parts require more data. Contrast is very important for the scanner to
detect what to scan and what not to scan. If it doesn’t seem to catch the surface,
try using a background that is the same color as the part you are trying to scan.
I had a “Out of memory” error and now there is no surface or facets in my
session.
Your data was not lost in the process. The new memory manager will inform you
that it is out of memory and was not able to rebuild the surface/facets. You can
set your resolution to a lower level and try to rebuild the surface. If this does not
45
work for any reason, set the resolution to low, save your session, restart ZScan
and try to open it.
I am experiencing slow frame rates when scanning.
I am experiencing display problems when using ZScan.
ZScan requires high system performances. Please make sure that you are not
running your laptop computer on battery power and that you are any possible
power saving options in the computer and video card settings are turned off or
configured for maximum performance.
Windows Vista Users
ZScan 3D display is using the OpenGL technology. In Windows Vista, Microsoft
does not natively support that technology. Video cards manufacturer are now
responsible for the OpenGL support. Drivers are at an early stage and major
video card manufacturers are still reporting problems under Vista.
Latest available Windows Vista drivers for the laptops sold with our systems are
available for download on our website for customers under maintenance. Please
install those drivers if you are using our laptops under Vista to ensure best
possible performances.
My scanner refuses to calibrate.
First, make sure that you are scanning your calibration plate properly. You can
also check for any reflective object as far as 2 feet around the plate on each side.
You can also try to "Reset" your Configuration File by using the Default button in
the Calibration Window.
The "Power" LED on the scanner does not turn on even when I connect it.
First, make sure that the power supply is connected properly in the power source
and in the PCMCIA card. If the LED still does not turn on, check for any damage
on the power supply connectors and wires. You can also check your Fire Wire
cable for any connection problem.
I can't see the "3D Imaging Devices in Windows Device Manager.
This may be a connection problem with your scanner. Please check every link of
the connection chain and make sure it is well connected. If possible, try isolating
the portion of the link that seems problematic. Contact customer support with all
this information and your scanner's serial number.
