The perfect base plate position will be achieved later on through the Reset Axisprocedure described in the "Operations" paragraph.

CAUTION

· Do not perform this operation while the scanner is turned on!

NOTE

· It is suggested to keep the packaging in case you need to ship the scanner for technicalassistance.

6.3 Hardware setup

NOTE

7 Operations

The following pages are to provide basic information and tips which are essential forsuccessful and error-free working.

7.1 Putting into operation

CAUTION

· Do not operate scanner with dust cover!

1. Turn on the rear mains AC switch.

2. Turn on the scanner using the front operating On/Off button.

After a few seconds, the projector should light up the rotary table with a cara Scan 4.0warm up sequence:

19Operations


When the warm up sequence is finished the scanner will be in idle mode ready for theoperations. The PC monitor will show the standard Windows desktop page.

On the left side there are the two icons belonging to cara software application:

cara Scan and cara CAD. See cara Scan or cara CAD User's Guide for more details aboutthem.

NOTE

· The scanner in idle mode do not project any light to save energy.

7.1.1 Installation Testing

NOTE

· Installation testing is required only the first time the scanner is extracted from thepackage or moved to another location. During the day by day operations this activity isnot required.

To check if the scanner is working properly, two mandatory steps have to beperformed:

1. Perform a Reset Axes.

2. Acquire a model in Basic Mode.



7.1.1.1 Reset Axes

The Reset Axes command has to be used every time the scanner base plate is notproperly oriented. For a more detailed description see Reset Axes in the cara Scan User'sGuide. Follow the below steps:

1. Close the front protection cover.

2. Double click on the cara Scan icon in the desktop .

3. In the drop down menu click on Tool -> Reset Axes or directly the icon .

4. Wait until a dialog box confirms the end of the process.

In a few seconds the plate will start to rotate and tilt. It will stop automatically aftercompleting a predetermined series of rotations, after which it will be aligned.

NOTE

· The Reset Axes command has to be used every time the scanner stops unexpectedlyand the base plate is not properly oriented.

· Do not insert any model in the scanner while performing a Reset Axes!

· If the scanner do not perform a reset axes properly see the paragraph"Troubleshooting, Error and Causes".

7.1.1.2 Basic Mode Acquisition

The Basic Mode is a general purpose application used to test the scanner or to acquire avery simple model. The Basic Mode calls the low level acquisition engine, Lumen, andmove the model in several predefined positions in order to fully cover it from camerasand projector point of view. From each position a points cloud is generated, all the pointsclouds are aligned and merged together to create the final mesh, last operation is calledFinalize. For a more detailed description see Basic Mode in the cara Scan User's Guide.

Follow the below steps:

1. Fix a model on the working plate using Blu-Tack adhesive. The working plate has a planar reference face: A. The incisors teeth have to be oriented as in the image below:

A|

21Operations


2. Insert the working plate in the scanner, align the flat side of the working plate withthe base plate one. In this way the incisors are to the back of the scanner.

3. Close the front door.


5. Click the blue arrow button "Scan" in the top left corner of the monitor. The"Basic Mode" dialog box appears.

6. Keep all the parameters by default.

7. Click on the "Scan" button to start the acquisition process. After the first 3 positionswill have been acquired, some points should be visible in the working area.

8. When the "Finalize" button becomes active, click on it to transform the pointsinto a mesh.

NOTE

· The scanning process can be interrupted in any moment by clicking the red square

button "Stop" , the scanner stops immediately to work and all the data will bedischarged. Use a Reset Axes command to restore the right plate position.



· If the system do not perform the acquisition process correctly, see the paragraph"Troubleshooting, Error and Causes".

· As soon as scanning cycle has been started, the front door needs to stay closed all thetime. In case door needs to be opened scanning process will be stopped and all datawill be lost.

7.2 Putting out of operation

Turn off the scanner using the "Shutdown" button in the desktop Start menu or theoperating On/Off button at the front.

NOTE

If the unit is not to be operated for longer periods:

· Turn off the rear mains AC switch.

· Unplug the mains connecting cable.

· Clean the scan chamber.

· Close the front door.

· Cover the scanner with the enclosed dust cover to prevent accumulation of dust inside.

23Operations


7.3 Acquiring high models

It is possible to acquire a very high model, more than 50 / 55 mm (1.97 / 2.17 inch) up to65 / 70 mm (2.56 / 2.76 inch).

Follow the below steps:

1. Remove the working plate from the scanner.

2. Remove the retention screw from the base plate using the 2.5 mm (0.1 inch)hexagonal (Allen) tool (I) provided in the accessory box.

3. Gently remove the base plate just lifting it by hands.

4. Engage directly with the working plate the movable tray.

NOTE

· Do not acquire model less than 55 mm (2.17 inch) high with the working plate in thelower position.

· Do not calibrate the scanner without base plate.

· It is strongly suggested to use the base plate always with the retention screw.

See the cara Scan 4.0 User's Guide manual for further details. Double click on the

Scanner icon in the desktop. In the drop down menu click on Help -> Contents.

9 Maintenance

Proper function and operational reliability of the unit are only ensured if the requiredtests, maintenance and service work are performed by Kulzer GmbH service agents orpersonnel instructed by Kulzer GmbH.

Kulzer GmbH will not accept any liability for damage – in particular personal injury –resulting from improper maintenance or repair work which has not been performed byKulzer GmbH service agents or adequately trained personnel or if no original spare partsor accessory parts have been used during the exchange of parts.

We recommend to conclude a maintenance contract with our service agents; an offercan be requested there: see paragraph "Service".



9.1 Maintenance and care


· Prior to maintenance and service work the unit must be switched off and unplugged!

NOTE

· Dust and following inside pollution can be a major problem for the scanner. Itsaccumulation in vents, heat-sinks and fans can block cooling air making the equipmentless reliable. If the scanner is installed in a very dusty environment, try to protect thedevice as much as possible. When not used always close the front door and use theenclosed dust cover to isolate it from environment.

CAUTION

cara Scan 4.0 mechanical parts do not require any maintenance.

· Do not lubricate tilting movement mechanism.

2. Close the front protection cover.


4. In the drop down menu click on Tool -> Calibration.

The "Calibration Mode" dialog box appears:

5. Click the "OK" button.

6. Wait a few minutes until a dialog box confirms the end of the process.

35Maintenance


NOTE

· The scanner uses white light during calibration.
