EXTRAORAL IMAGING PROCEDURES
Cassettes must not contain intensifying screens when using PSPs.
Note:
Take an X-ray Image
Put an image on the extraoral PSP by performing the following procedure.
1. Place the erased PSP into the appropriate X-ray cassette, with the Tube side
(sensitive side) of PSP towards Tube side of cassette.
2. Load cassette into the exposure device as previously done for film, and
take the exposure following the X-ray device manufacturer's instructions for
PSPs.
3. Bring the cassette containing the exposed extraoral PSP to the ScanX. The
PSP is now ready to be scanned.
Activate Scanner
Activate the ScanX by performing the following procedures.
1. Make sure the ScanX and computer components are correctly connected
as shown in Figure 1.
2. Switch the scanner from Standby to ON by pressing the membrane READY
switch (
3. Verify that both the green and blue LED indicators above the READY and
ERASER switches, respectively, illuminate. (Default has eraser mode ON)
Change in motor noise pitch levels is normal when switching to different resolution set-

ting selections.
4. Use the user-supplied authorized Imaging Software to activate the Scanner
and to select the desired image type and resolution.
5. Verify that the four Scanner track indicators illuminate green when the
Scanner has been activated, indicating a PSP can be fed into the ScanX.
1. Leave the four Plate Guides in place when scanning extraoral PSPs.
Note:
2. Only one extraoral exposed PSP can be fed into the ScanX at a time. The next PSP
may be fed only after all four track indicator light LEDs change from yellow to green.
Scanning and Erasing Plates
Scan and erase an extraoral PSP in one operation by performing the following
procedures.
1. Orient the cassette so that the Tube side is fac-
ing down and the hinge is away from you.
2. Open the cassette and grasp the PSP by its
ends with your finger tips, and quickly (mini-
mizing exposure to ambient light) move it
to the ScanX, with Tube side of PSP towards
ScanX.
3. Position the extraoral plate behind the four
Plate Guides against the curved surface and
gently slide the plate down (See Figure 11)
until the transport mechanism takes over and
the plate moves on its own.
4. At this point, all four track lights will turn yellow,
indicating the PSP has been sensed and the
Scanner is transporting the PSP .
