Primescan 2 Connection Error or "Cannot Find Network": What the Message Is Telling You

When a Primescan 2 reports a connection error or can't find the network, the cause is not always the scanner. The network, the workstation, the room, or the scanner's own ability to connect could each be responsible.

You can sort this out with a few checks. Start by determining whether the network actually disappeared or whether the scanner can no longer establish a connection to a network that is still there. If the problem follows the scanner across rooms, devices, and a confirmed-working network, professional diagnosis may be appropriate, and Repair.Dental can evaluate the unit.

What the Light-Orange Connection Indicator Means

Dentsply Sirona's documentation for the Primescan 2 describes a light-orange connection indicator. Treat it as a status signal that the scanner is not currently in a healthy connected state. It is not a diagnosis.

The indicator by itself does not tell you why. It cannot distinguish between:

a network that is down or out of range;
changed credentials or network settings;
a workstation or DS Core-side problem;
a scanner-side connection fault.

Confirm the exact wording and behavior in the operating instructions for your unit and software version. Don't assume a particular fault from the color alone.

Did the Network Disappear, or Can the Scanner No Longer Connect?

This distinction drives the rest of the diagnosis. Two tests answer it.

Test 1: Check Whether the Network Is Visible to Other Devices

Take a phone, tablet, or laptop to the operatory and look for the same network the scanner uses.

If other devices can't see or join the network, the problem is upstream: the router, access point, or network configuration. The scanner is probably reporting a real outage.
If other devices connect normally, the network exists, and suspicion moves toward the scanner, its connection settings, or the workstation pairing.

Check signal strength where the scanner is used as well. A network that is technically present but weak at the chairside can behave like a missing one.

Test 2: Observe How the Scanner Fails

Pay attention to the timing of the failure:

Never connects after a restart: this suggests a setup, credential, or configuration problem, or a scanner that can't join at all.
Connects, then drops mid-session: this points toward signal, interference, or an unstable link. The related problem is covered in our guide to Primescan 2 connection drops during scanning, so we won't repeat it here.
Worked yesterday, fails today with no changes: check for router updates, password changes, or IT work overnight before suspecting hardware.

Clinic-Side Checks to Run First

These are safe, non-invasive steps that any assistant or office manager can perform. Work through them in order:

Confirm the network is up by testing another device in the same room.
Restart the scanner connection using the normal power and reconnect procedure in the Dentsply Sirona instructions.
Restart the workstation or tablet paired with the scanner, since a stuck session on that side can mimic a scanner failure.
Check that the scanner is charged and seated or powered correctly. Low or unstable power can interfere with normal operation, so swap in a known-good battery if you have one.
Ask whoever manages your IT whether the network name, password, security settings, or access points changed recently.
Move the scanner closer to the access point, or test in a different operatory.

Record what you see at each step. That record helps your IT contact and a repair technician.

Reading the Pattern: What Your Observations May Suggest

What You Observe	What It May Suggest	Recommended Next Step
Other devices also can't find the network	Router, access point, or network outage	Contact your IT provider; the scanner is probably not at fault
Network visible to phones/laptops, not to the scanner	Scanner settings, pairing, or a scanner-side connection fault	Re-check credentials and settings; test in another room
Works in one operatory, fails in another	Signal strength, interference, or local network variable	Test access point coverage; avoid blaming the scanner yet
Fails on one workstation, works on another	Workstation, software, or DS Core-side issue	Troubleshoot that computer or tablet
Orange indicator persists in every room on a confirmed-working network	Stronger indication of a scanner-side problem	Consider professional evaluation

The last row is the important one. Once the room, the network, and the workstation are ruled out, the scanner is what remains.

Separating Network Problems from DS Core and Workflow Issues

A Primescan 2 that "can't find the network" is sometimes a problem in the surrounding software workflow. Practices using DS Core may see symptoms that look like a connection fault but originate elsewhere.

Consider whether any of the following changed:

a software or operating system update on the workstation;
a new firewall or security rule;
a recently changed login, account, or practice setting;
a different computer or tablet being used.

If the scanner connects to the network but the workflow still fails, you may be dealing with a software or account problem rather than a scanner fault. Check with Dentsply Sirona support or your software administrator about those variables.

Signs the Problem May Be Inside the Primescan 2

A scanner-side fault becomes more likely when several of these hold at once:

The error follows the scanner into other operatories and onto other compatible workstations.
The network is confirmed working for every other device, with good signal at the scanner.
The failure repeats after restarts, a known-good battery, and verified settings.
The scanner has a history of a drop, impact, liquid exposure, or recent intermittent behavior.

Repair clue: If the same orange indicator or "cannot find network" message appears in every room, on every compatible workstation, and on a network other devices use without trouble, the diagnostic picture shifts away from the practice environment and toward the scanner itself.

None of this confirms hardware failure. It does mean further clinic-side troubleshooting is likely to produce diminishing returns. Rather than continuing to guess, a practice can request a professional evaluation through Repair.Dental's Dentsply Sirona intraoral scanner repair service.

What Not to Do

When appointments are being affected, it is tempting to try aggressive fixes. Avoid these:

Opening the handpiece or attempting internal repairs. This can cause damage and complicates later diagnosis.
Using non-approved chargers or accessories to test power theories.
Repeatedly factory-resetting settings without recording the original configuration.
Changing network infrastructure solely to test the scanner, without involving whoever manages your IT.

Getting a Primescan 2 Evaluated Without Extended Downtime

If the checks above point toward the scanner, the next step is a structured evaluation. Repair.Dental works with intraoral scanner repair cases across scanner platforms, and the process is designed for busy practices.

Your team can print a shipping label for intraoral scanner repair to send the unit in. After shipping, you can use the repair tracking page to follow progress. When you contact the team, include your notes on which tests you ran, which rooms and workstations you tried, and exactly how the indicator and error message behaved. That history can shorten diagnosis.

Frequently Asked Questions

Why does my Primescan 2 say it cannot find the network?

The scanner may be out of range, the network may be down, settings may have changed, or the scanner may have a connection fault. Testing the network with another device and trying another operatory usually narrows it down.

Does the orange connection light mean the Primescan 2 is broken?

Not necessarily. The indicator signals a connection problem, but it does not identify the cause. Check the network and the workstation first, then confirm the indicator's exact meaning in the Dentsply Sirona operating instructions.

Can a Primescan 2 work offline?

Capabilities depend on your configuration, software, and workflow. Check Dentsply Sirona's documentation for your setup rather than assuming the scanner can operate without a connection.

How do I know if the problem is my Wi-Fi or the scanner?

Test whether other devices see and join the same network in the same room. If they do, and the scanner still fails on a confirmed-working network in several locations, the scanner becomes the more likely source.

What should I do before sending a Primescan 2 for repair?

Document your troubleshooting, including the rooms, workstations, and batteries tested. You can also check Repair.Dental's frequently asked questions or contact the team with your questions before shipping.

When a Primescan 2 Network Error Becomes a Repair Decision

A Primescan 2 connection error or "cannot find network" message usually starts as a network question: did the network disappear, or can the scanner no longer connect? Rule out the router, the signal, the workstation, the power source, and recent settings changes first.

A scanner-side fault becomes more likely when the orange indicator or error persists across rooms, workstations, and a confirmed-working network. At that point, more guesswork mostly costs chair time and patient scheduling.

Repair.Dental can evaluate the Primescan 2 and determine whether the scanner has a repairable fault, so your practice can stop repeating unsuccessful troubleshooting and return to reliable scanning. Share your test notes when you contact Repair.Dental.
