1.1 Introduction
This manual describes how to use the Scan eXam
digital imaging plate scanner (the unit) which is
part of the digital intraoral imaging plate system
(the system). The complete system comprises the
following:
- the Scan eXam digital imaging plate unit (the
unit).
- Dental Imaging Plates (IPs), protective covers,
hygiene bags and other related imaging plate
accessories.
- A PC (not supplied) in which suitable dental
imaging software.
- A local area network (LAN) cable (not supplied)
will be required if the system is to be used in a
network.
The unit is a laser scanning device designed to
automatically read reusable dental intraoral imaging
plate sizes 0, 1, 2, and 3. The Occlusal 4C kit also
allows two size 3 imaging plates to be used to take
an occlusal projection image. After reading the
images can be viewed on the PC using the dental
imaging sofware.
The unit can either be connection directly to the PC
or to network via the LAN cable.
The unit can be set up to work with a single PC, the
single user configuration, or with several PCs, the
Express Share (multiple user) configuration.
With the Express Share configuration up to eight
PCs can be used, one at a time, with the unit.
NOTICE:
Only personnel trained and authorized by the
manufacturer of the unit are allowed to install and
configure the unit.

3 Using the system
3.1 General
For optimum performance only use IPs, protective
covers and hygiene bags designed for this unit and
supplied by authorized distributors.
The manufacturer of this unit will not be held re-
sponsible for any problems caused by using acces-
sories from other manufacturers.
Proper handling, cleaning and storage of the IPs
ensures the best image quality and maximum ser-
vice life of the IPs. Refer to section 4. Handling and
care of imaging plates.
IMPORTANT NOTICE:
If you are using the system for the first time check
the setup options to ensure that they are suitable
for your work methods and dental environment.
See section “B.3 Setup options in CLINIVIEW”
or “B.4. Scan eXam settings with DTX Studio™
Core” for more information.
3.2 Preparing the system
1. PC: Switch on the PC connected to the unit.
2. PC: Open the dental imaging software and a
new or existing patient card where you wish to
store the intraoral images.
3. Press the power on/offkey to switch the unit
on.

3. Using the system
The startup animation will appear on the display
and the unit will carry out self test during which
the IP carrier will slide out of the unit door.
When the status light turns green and ready ani-
mation, indicating IP insertion, appears on the
unit display, the unit is ready to use (in the ready
state).
NOTICE:
If the ready animation does not appear, check
the system setup described in the installation
instructions.

3.3 Preparing an IP for exposure
IMPORTANT NOTICE:
If an IP is being used for the very first time or if it
has not been used within the last 24 hours, it must
be erased before use to remove any fogging caused
by background radiation. See section ”3.11 IP eras-
ing mode (Initial erasing of the IPs)”.
CAUTION:
When handling IPs, protective covers and hygiene
bags take all appropriate measures and precautions
to prevent cross contamination.
NOTICE:
If you are taking an occlusal projection exposure
refer to section 3.12 Taking an occlusal projection
image and to the separate instructions supplied
with the Occlusal 4C kit.
1. Place the IP you wish to use onto a protective
cover. The light blue side (sensitive) of the IP
must face and be placed on the half of the pro-
tective cover that is the same shape as the IP.
2. Fold the half of the protective cover with the
semicircular cutout over onto the IP. The metal
disk on the back (black side) of the IP must ap-
pear in the semicircular cut out.
3. Turn the protective cover and IP over so that the
black side of the protective cover is uppermost.
This makes it easier to slide the protective cover
and IP into the hygiene bag.

14 SCAN EXAM
3. Using the system
4. Slide the protective cover and IP into the hy-
giene bag as far as they will go. Make sure that
the black side of the protective cover is on the
same side as the black side of the hygiene bag.
5. Peel offthe cover paper from the sealing tape
and then fold the flap, along the pre-formed line,
over and onto the sealing tape.
6. Press and slide your thumb along the tape to
ensure that the flap is properly sealed.
7. Turn the sealed hygiene bag over and check
that the IP and protective cover are in the cor-
rect position.
You must be able to see the light side of the pro-
tective cover and the metal disk on the IP.
