1. REQUIRED INSTRUMENTS
Calibration kit, including:
• Support plate
• Dentition phantom
• Aluminium lter
• Laser reference sheet
• Allen wrench set
• Screwdriver set
When you will be required to assemble the support plate and
the dentition phantom, remove the chinrest from the machi-
ne and insert the highlighted pins into the holes where the
chinrest was assembled.

3.1 X-RAY ALIGNMENT CHECK
The aim is to check that the X-ray beam is inside the
red demarcation lines;
click on “Start procedure”

10
hyperion X5 2D/3D
EN
2D/3D OPT E.L. CALIBRATION MANUAL
Remove any object between source and sensor and
press “Start”
Press the button when prompted.
Check that the entire length of the X-ray beam is cen-
tred inside the red lines (compare with the following
images), in particular concerning rotation, horizontal
alignment and vertical alignment.
If adjustments are necessary, open the generator co-
ver and operate on the collimator as follows:
Upper part Lower part

• Rotation
If the X-ray beam is turned, open the monobloc cover
and slightly loosen the following screws (A, B,C):
Correct the rotation manually; tighten the screws, se-
lect “Image not centred” and press “ok”.
Repeat the procedure until a perfectly vertical image
is obtained.

• Horizontal alignment
Slightly loosen the following screws (D, E):
Correct the horizontal alignment manually; tighten the
screws, select “Image not centred” and press “ok”.
Repeat the procedure until a horizontally-centred ima-
ge is obtained.

• Vertical alignment
Slightly loosen the following screws (F, G, H, I).
Correct the vertical alignment manually; tighten the
screws, select “Image not centred” and press “ok”.
Repeat the procedure until a vertically-centred image
is obtained.
When the image is perfectly centred, select “Image
centred” and press OK; the software will automatically
check the proper alignment even for the Bitewing and
Children panoramic positions.
At the end of the procedure, press Ok to conrm and
save the data.

3.2 SENSOR CALIBRATION CHECK
Press “Start procedure” and make sure that any object
between source and sensor has been removed.
The procedure is automatic; just press the X-ray but-
ton when required; at the end, save the data.

3.3 VERIFYING THE MECHANICAL CENTERING
Remove bite, chinrest and aluminium lter and posi-
tion the calibration phantom as shown in the gure.
Click on “Acquire”.
The calibration tool will acquire a complete panora-
mic image and will display it; make sure that the fo-
cus is centred with respect to the series of circles in
the middle of the image, i.e. the number of off-focus
circles must be the same both above and below the
median horizontal line.

2D/3D OPT E.L. CALIBRATION MANUAL
To correct the positioning of the vertical line, adjust
the highlighted grub screws and screws (placed in the
lower part of the kinematic mechanism – remove the
accessory drawer to see them).
If the image obtained is similar to the following one,
adjust the left-hand screw and grub screw; slightly lo-
osen screw B and tighten grub screw A (some strength
is necessary) to modify the position of the chinrest.
Vice versa, if the image is similar to the following one,
adjust the right-hand screw and grub screw.
At the end of each adjustment, press “Retry” to acqui-
re a new image and assess it; if necessary, repeat the
operation until an image similar to the following one
is obtained.
To change the image focus position, modify the value
contained in the “offset Y” eld, conrm by means of
the arrow and press “Retry” in the dialog box in the
foreground.
At the end of the procedure, when the focus is centred
and the line is perfectly vertical, press “OK” to conrm
and save the data.

3.4 LASER CALIBRATION
Position the laser reference template on the support
(as shown in the gure)
Press “Start calibration”

The machine will turn automatically until it has rea-
ched the right position; assess the alignment betwe-
en the three laser beams (midsagittal, canine and
Frankfurt plane) and the references on the template.
If one or more lasers are not aligned, use a gripper to
loosen the springs of the corresponding supports and
adjust them manually; the Frankfurt plane laser and
the canine laser are inside the generator block.
The midsagittal laser is under the mirror.
At the end, press “Exit”.

Select “Device data” and “Tubehead calibration data”.
Select the folder where the calibration data copy is
going to be saved and conrm.
