Dental imaging equipment is essential for diagnosis in the modern clinic, but like any technology, it is subject to occasional failures or problems. Equipment that won't turn on, poor image quality, or an unexpected error message can disrupt workflow and cause frustration.

Although many problems require the intervention of a qualified technician, there are several basic checks and solutions that the clinic staff can perform before calling support. Knowing how to identify and resolve simple issues can save time, avoid unnecessary service calls, and keep your clinic running smoothly.

This quick guide provides a roadmap for troubleshooting some of the most common problems encountered with dental X-ray machines (intraoral, panoramic, and CBCTs), focusing on safe checks and actions that can be taken by the team before escalating to technical support.

(Warning: Safety first! Never attempt to open or repair internal components of the equipment. This guide covers only external and basic checks. When in doubt, ALWAYS call authorized technical support.)

Problem 1: Equipment Does Not Turn On

Symptom: The machine (intraoral unit, Pano, CBCT) or the acquisition computer shows no sign of life when trying to power on.

Basic Checks (Clinic Staff):

[ ] Power Cord: Check if the power cord is firmly connected both at the wall outlet and the equipment inlet (and computer, if applicable). Try another outlet if possible.
[ ] Circuit Breaker: Check the clinic's electrical panel to see if the breaker corresponding to the equipment's circuit has tripped. Reset it once. If it trips again, call an electrician – DO NOT try to reset repeatedly.
[ ] Main Power Switch: Ensure the equipment's main power switch (usually on the back or side) is in the "On" position.
[ ] Emergency Stop Button: Some equipment (especially Pano/CBCT) has a red emergency stop button. Check if it has been accidentally pressed. If pressed, twist it to release.
[ ] UPS (Uninterruptible Power Supply): If the equipment is connected to a UPS, check if the UPS is turned on and functioning correctly (indicator lights, battery).

Next Step: If none of these checks resolve the issue, contact technical support.

Problem 2: Connection Failure with Computer (Digital Equipment)

Symptom: The acquisition software does not recognize or cannot communicate with the intraoral sensor, Pano, or CBCT.

Basic Checks (Clinic Staff):

[ ] Connection Cables:
- Intraoral Sensor: Check the USB cable connection (or specific interface) at the sensor and the computer. Try another USB port. Inspect the cable for damage.
- Pano/CBCT: Check the network (Ethernet) cable connection at the equipment and the computer/network switch. Ensure the connection lights at the network point are lit.
[ ] Restart Software: Completely close the image acquisition software and reopen it.
[ ] Restart Computer: Restart the acquisition computer.
[ ] Restart Imaging Equipment: Follow the manufacturer's recommended procedure to turn the X-ray equipment (Pano/CBCT) off and on. Wait a few minutes before turning it back on.
[ ] Check Network (with IT help, if needed): Verify that the acquisition computer and imaging equipment are on the same network and that IP settings are correct (as defined during installation).

Next Step: If the problem persists, consult the manual for specific connection errors or contact technical/IT support.

Problem 3: Error Messages on Panel/Software

Symptom: The equipment displays a numeric error code or a specific error message on the control panel or software screen.

Immediate Action (Clinic Staff):

[ ] Note the Error: Record the exact error code or message displayed.
[ ] Consult the Manual: This is the most important step. Look up the error code/message in the troubleshooting section of the equipment's user or service manual. The manual usually explains the error's meaning and recommended actions (which can range from a simple restart to immediately calling technical service).
[ ] Follow Manual Instructions: Perform only the actions recommended in the manual for that specific error. Do not attempt undocumented procedures.

Next Step: If the manual indicates the need for technical service, or if the recommended actions do not resolve the error, contact authorized technical support, providing the exact code/message.

Problem 4: Image Quality Issues

Symptom: Acquired images are too light, too dark, noisy, blurry, or have artifacts.

Basic Checks (Clinic Staff):

[ ] Exposure Settings: Verify that the parameters (kVp, mA, time) are correct for the exam type, patient (adult/child), and receptor (sensor/PSP/film). Incorrect settings are a common cause (Dentalcare.com).
[ ] Patient/Sensor/Equipment Positioning: Review positioning techniques. Positioning errors are the most frequent cause of non-diagnostic images (especially in panoramics - see our guide on common errors!).
[ ] Sensor/PSP Plate Condition: Inspect for scratches, bite marks, or dirt. Clean according to manufacturer instructions. Worn PSP plates may need replacement.
[ ] Protective Barriers: Ensure barriers are not folded or wrinkled over the active area of the sensor/plate.
[ ] Movement: Check if there was patient or equipment movement during exposure.
[ ] Calibration (Consider): If images are consistently light/dark despite correct settings, the equipment might need calibration (a task for a technician, but can be suggested to support - DentalTI).
[ ] Viewing Software: Check if monitor or software brightness/contrast settings are misadjusted.

Next Step: If quality issues persist after checking technique and settings, consult the manual or contact technical support.

Problem 5: Mechanical Failure (Pano/CBCT)

Symptom: The rotational arm or the vertical movement mechanism does not move, moves erratically, makes loud noises, or stops mid-cycle.

Immediate Action (Clinic Staff):

[ ] Emergency Stop: If there is immediate risk, use the emergency stop button.
[ ] Check Obstructions: Ensure nothing is physically blocking the equipment's movement.
[ ] DO NOT FORCE: Never try to force a jammed mechanical component.
[ ] Note Details: Observe exactly what happened, at what point in the cycle the failure occurred, and what noises were heard.
[ ] Power Off (if safe): If possible and safe, turn off the equipment using the main power switch.

Next Step: Immediately contact authorized technical support. Mechanical problems almost always require professional intervention.

When to Call Technical Support? ALWAYS When in Doubt!

Call authorized technical support if:

Basic checks do not resolve the problem.
The manual explicitly indicates to call service.
There is any sign of physical damage to the equipment or cables.
Mechanical failures occur.
There are persistent or complex errors.
You do not feel safe performing any check.

Troubleshooting: A Systematic Approach

Having a quick guide for common problems can help your team handle minor glitches efficiently. Remember to approach troubleshooting systematically, starting with the simplest and safest checks. Above all, prioritize safety and don't hesitate to call qualified professionals when needed. Keeping your manuals accessible and your team trained on basic procedures is fundamental.
