Why does my Styku scanner intermittently fail to start or complete scans?

If your scanner is failing inconsistently — working one day and not the next, getting stuck on the success screen, or not saving completed scans — start with the physical environment before assuming it's a software issue. The most common cause of intermittent scan failures is the scanner being too close to a wall, mirror, or nearby object.

What You May Be Experiencing

These symptoms have been reported together as part of this type of issue:

Scanner throws errors at the start of a scan
Scan appears to complete but gets stuck on the success screen
Completed scans are not saved in Styku Studio
Patients do not receive their results in the Styku mobile app
The problem comes and goes — the scanner works on some days but not others
Frequent software updates seem to coincide with failures

Step 1 — Check the Physical Environment (Do This First)

The most common and easily overlooked cause of intermittent scan failures is the scanning environment. Check these before anything else:

Turntable clearance: Confirm there is at least 14 inches of clear space on every side of the turntable (18 inches recommended). Measure with a tape measure — eyeballing it is not reliable.
Camera tower distance: Confirm the camera tower is 25 inches from the center of the turntable.
Remove nearby objects: Clear everything within arm's reach of the turntable — gym bags, chairs, equipment, clothing racks, or anything that may have been moved near the scanner.
Check for reflective surfaces: Mirrors, glass partitions, and polished floors within the scan field can interfere with the depth sensor. If possible, cover or reposition the scanner away from these.
Block all natural light: Close blinds and curtains fully. Direct sunlight entering the room — even at an angle — can cause intermittent scan failures that seem random but track with time of day or weather.

If your environment has changed since the scanner was last working well — a piece of equipment moved closer, a blind left open, furniture rearranged — that is almost certainly the cause. Fix the environment and run a test scan before contacting support.

See [Why does my scanning environment affect scan quality — and how do I set it up correctly?] for the full environment checklist.

Step 2 — Restart the Styku Laptop

Fully shut down the Styku laptop (Start → Shut Down — not Sleep). Allow it to restart completely. Do not just close and reopen the app.

After restart:

Wait for any pending Windows updates to finish before attempting a scan
Open Styku Studio and check for any pending app updates

Step 3 — Check Your Internet Connection

Styku Studio requires an active internet connection to sync scan data and validate your license. Confirm the laptop is connected to Wi-Fi or a wired network by pressing the Wi-Fi icon on the bottom right of the screen. Open a browser and verify internet access by loading a site such as www.styku.com.

If you are traveling and not at your home location, you may need to hotspot your mobile phone to connect the laptop to the internet.

Step 4 — Wait for Any Pending Updates to Finish

If Windows or Styku Studio is in the middle of an update, wait until it completes and the system restarts before attempting a scan. Scans attempted mid-update may fail in ways that look like hardware or sensor issues.

Step 5 — Attempt a Test Scan and Document What Happens

Run a test scan with a staff member (not a patient) and note exactly what happens — which step it fails at, what message appears, and whether the scan saves afterward. Take photos or screenshots of any error messages. This documentation is important if you need to contact support.

What to Know About Software Updates

Styku Studio updates automatically when connected to the internet. In some cases, an update may not complete cleanly, which can affect scanner performance. If failures consistently appear after an overnight update, note the date and time and include that in your support ticket — it helps the team correlate the failure with a specific update version.

Viewing Scan Data on Another Computer

If you need to review saved scan profiles while troubleshooting (for example, to confirm whether scans are saving at all), it is possible to install Styku Studio on another Windows computer and log in to your existing Styku account. You will need a viewing license key from Styku to activate the additional device. If you do not have one, you can request it through the Styku Business Portal at https://styku.com/portal.

How to Get Help

If the steps above do not resolve the issue, contact Styku support. Support may request a TeamViewer remote session to access your laptop and investigate directly.

Log in to the Styku Business Portal at styku.com/portal and submit a support ticket using the Need Help? form. You can expect a response within one business day. If you need to schedule a session at a specific time, you can request that when submitting your ticket.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: the date(s) and times failures occurred, a description of which step the scan failed at (startup error, stuck success screen, missing saved scan, etc.), photos or screenshots of any error messages, whether failures seem to follow software updates, and the Styku Studio software version shown in the app.
