Accuracy of a robotic-driven imaging that generates sharp, clear images without sacrificing savings Triple laser positioning Automatic Exposure Control (AEC) Full scope of panoramic projections and cephalometric options.
Key tips
- ·Biological-indicator verification applies to dental sterilizers exactly the same as hospital CSSD - no exception for smaller units.
- ·"Sounds different" is often the first real report of handpiece bearing wear, not an outright failure - investigate early rather than waiting.

Error Codes
Extracted directly from this unit's own service manual.
F.3.1This alarm indicates that the temperature measured over the power transistors (by a PTC sensor) of the converter board has exceeded the limit (>80° C).
Check whether the LED H11 is ON (ON=OK, OFF=NOT OK). Possible causes: 1. ambient temperature too high 2. converter board defective 3. temperature sensor defective 4. power transistors defective. If the converter board PQ1 needs to be replaced, the service programs Tube calibration and Vf tube editing must be performed. The alarm is captured and stored as soon as it is detected. Press the RESET pushbutton on the control panel to cancel the alarm (if expired).
F.3.2This alarm message appears on the display when the maximum load admissible for the tubehead has been reached. The host computer board PC1 keeps a constant check on the load applied to the tubehead and when the maximum limit is reached, it disables the possibility of making another exposure and displays the cooling down time (in seconds). The message appears on the display at the end of the reset c
If the alarm stays on it may mean: 1. host computer board PC1 damaged 2. flash memory of the host computer board damaged. If the host computer PC1 needs to be replaced, remember to remove the EEPROM D38 from the old board and mount it on the new one, otherwise all the following parameters will be lost: UVCF DBMJCSBUJPO 9 : 3 BOE $ NPWFNFOU TUBSU QPTJUJPOT MBOHVBHF PG UIF NFTTBHFT DVTUPNJ[FE FYQPTVSF QBSBNFUFST L7 BOE N " &$ DBMJCSBUJPO BOE DPOGJHVSBUJPO. If you forget to do this, recover the information from the System Configuration Chart (see Section C).
F.3.3This alarm message appears on the display when the X-ray command has been released during a working cycle but out of the X-ray phase (i.e. when the rotating arm is in the acceleration phase and the exposure has not yet started).
Press any pushbutton of the control panel to cancel the alarm. If the alarm is generated outside the above mentioned conditions it may mean: 1. host computer board PC1 damaged 2. X-ray command damaged 3. bad connection between host computer board PC1 and X-ray command. If the host computer PC1 needs to be replaced, remember to remove the EEPROM D38 from the old board and mount it on the new one, otherwise all the following parameters will be lost: UVCF DBMJCSBUJPO 9 : 3 BOE $ NPWFNFOU TUBSU QPTJUJPOT MBOHVBHF PG UIF NFTTBHFT DVTUPNJ[FE FYQPTVSF QBSBNFUFST L7 BOE N " &$ DBMJCSBUJPO BOE DPOGJHVSBUJPO.

F.3.4This alarm message appears on the display when the reset cycle has been stopped by pressing the DUMMY RUN pushbutton on the operator console, or when the dummy run cycle has been stopped by releasing the DUMMY RUN pushbutton.
Press any pushbutton of the control panel to cancel the alarm. If the alarm is generated outside the above mentioned conditions it may mean: 1. host computer board PC1 damaged 2. X-ray command damaged 3. bad connection between host computer board PC1 and X-ray command.

F.3.5This alarm message appears on the display when the X-ray command has been released during the X-ray exposure.
Press the RESET pushbutton on the control panel to cancel the alarm. If the alarm is generated outside the above mentioned conditions it may mean: 1. bad connection between host computer board PC1 and DPOWFSUFS CPBSE 12 DPOOFDUPS 9 2. DPOWFSUFS CPBSE 12 EBNBHFE 3. X-ray command damaged 4. bad connection between host computer board PC1 and X-ray command. If the converter board PQ1 needs to be replaced, the service programs Tube calibration and Vf tube editing must be performed.
F.3.6This alarm appears on the display in the following conditions: a) when the X-ray command is pressed during the switching on of the system. b) when the X-ray command is kept pressed for more than 6 s after the end of the exposure cycle. The alarm disappears automatically when the X-ray command is released.
If the alarm stays on it may mean: 1. X-ray command damaged 2. host computer board PC1 damaged 3. bad connection between host computer board PC1 and X-ray command.

If the alarm stays on (so with the cassette properly inserted in the cassette carriage) it may mean: 1. wiring of the optoswitch S16 damaged (panoramic cassette present) 2. wiring of the microswitch S23 damaged (ceph cassette present) 3. DPOWFSUFS CPBSE 12 EFGFDUJWF. If the converter board PQ1 needs to be replaced, the service programs Tube calibration and Vf tube editing must be performed.
F.3.8This alarm message is always related to the optoswitch S16 that SFDPHOJ[FT UIF JOTFSUJPO PG UIF QBOPSBNJD DBTTFUUF JOIN UIF DBTTFUUF carriage, as the alarm Cassette (see the description in this section of the Service Manual) but it indicates that the optoswitch is broken.
Press the RESET pushbutton on the control panel to cancel the alarm.

This alarm is generated when conditions: a) at the end of the Reset cycle b) when the X-ray command is pressed and the cassette is not inserted in the cassette carriage (panoramic and ceph). Press any pushbutton of the control panel to cancel the alarm. If the alarm stays on (so with the cassette properly inserted in the cassette carriage) it may mean: 1. wiring of the optoswitch S16 damaged (panoramic cassette present) 2. wiring of the microswitch S23 damaged (ceph cassette present) 3. DPOWFSUFS CPBSE 12 EFGFDUJWF. If the converter board PQ1 needs to be replaced, the service programs Tube calibration and Vf tube editing must be performed.
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No or inconsistent exposure / generator or tube-head error
- Note the exact error code and whether it is a kV / mA / preheat / interface failure.
- Check the mains supply, the dedicated circuit and the fuses.
- Check the tube-head and detector / sensor interface cable connections.
- Confirm the exposure switch is held for the full exposure and the warning light works.
- Escalate a confirmed tube-head / HV / generator fault; verify output with a dental X-ray meter after any repair.
Symptom: Blurred or distorted panoramic image / layer or focal-trough errors
- Confirm patient positioning (bite block, chin rest, light guides).
- Check the rotation drive belt, motor and encoder for wear or slip.
- Run any image-calibration / geometry routine.
- Verify the focal-trough / layer selection.
- Escalate a drive / reconstruction fault to the OEM.
Symptom: Sensor / CCD / CBCT detector fault (dead lines, artefacts, no image)
- Swap in a known-good sensor if available.
- Inspect the sensor cable for kinks or breaks.
- Run the detector calibration / dead-pixel map.
- Expose a phantom and check uniformity.
- Replace or refer the detector as isolated.
Symptom: Software / acquisition fault (image will not acquire, save or display)
- Check the TWAIN / driver and the acquisition PC.
- Restart the acquisition software and the unit.
- Confirm the practice-management link.
- Update to compatible driver / software versions.
- Escalate a persistent acquisition fault to the OEM.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Improper hardware was used during installation of the eXpert DC Intraoral X-Ray system units causing drifting of the tubehead assembly.
- RECALL
There is an anomaly in the Orthoralix firmware which can cause a message corruption which will distort the patient image being transferred from the X-Ray system to the PC. This image distortion/corruption (distorted, fragmented, flipped, negative, reversed or had lines across them) is most likely to occur during periods of high network traffic and is significant enough that it is clear and obviou
- RECALL
The Automatic Exposure Control (AEC) feature located on the control panel of the Orthoralix 8500 Panoramic Dental X-Ray System was functional, but was subsequently disabled in units manufactured starting 5/17/10. North American units manufactured between 12/4/09 and 5/16/10 had functioning AEC buttons, but their manuals stated they were disabled. Units intended for International distribution bet
- RECALL
The intraoral x-ray systems were installed improperly with incorrect screws which allow the unit to pull away from the wall when the arm is fully extended. This condition may harm the patient.
