Why do the sensor lights turn off on the Styku camera tower during a scan?

Why do the sensor lights turn off on the Styku camera tower during a scan?

If the lights on your Styku camera tower switch off during a scan, the camera is losing power or its connection to the laptop. In most cases, this is caused by a loose USB cable, a power setting on the laptop, or a software conflict — all of which you can check yourself before contacting support.

Step 1: Check the USB Cable Connection

  1. Turn off the Styku Studio software.
  2. Unplug the USB cable from the back of the camera tower.
  3. Unplug the other end from the laptop.
  4. Plug both ends back in firmly until they click or seat fully.
  5. Restart Styku Studio and attempt a test scan.

Step 2: Try a Different USB Port on the Laptop

If the lights still go off:

  1. Unplug the tower's USB cable from its current port.
  2. Plug it into a different USB port on the laptop.
  3. Wait 10–15 seconds for the computer to recognise the device.
  4. Restart Styku Studio and try again.

Step 3: Turn Off USB Power Saving (Windows Setting)

Windows can cut power to USB devices to save energy. This can interrupt the camera mid-scan.

  1. Click the Start button and search for Device Manager. Open it.
  2. Expand the Universal Serial Bus controllers section.
  3. Right-click each USB Root Hub entry and select Properties.
  4. Click the Power Management tab.
  5. Uncheck Allow the computer to turn off this device to save power.
  6. Click OK and repeat for each USB Root Hub listed.
  7. Restart the laptop and test a scan.

Step 4: Check for Audio Enhancement Settings (S100 Scanners)

On S100 scanners, certain audio or system enhancement settings have been known to interfere with camera performance and cause the sensor to drop out. If you are using an S100:

  1. Right-click the speaker icon in the Windows taskbar and open Sound settings.
  2. Find your playback device, click Properties, and look for an Enhancements tab.
  3. Check the box for Disable all enhancements if it is not already checked.
  4. Click OK and restart the laptop.
  5. Open Styku Studio and run a test scan. Confirm the camera frame rate is stable.

Step 5: Check the Camera Frame Rate in Styku Studio

A dropping or unstable frame rate is a sign the camera is struggling. If Styku Studio shows the camera frame rate dropping below 30 fps during a scan, note this and report it to support — it helps confirm whether the issue is hardware or software.

If the Problem Continues

If none of the above steps resolve the issue, the camera tower itself may need to be repaired or replaced. Styku support can advise on repair options (sending the tower in for service) or pricing for a replacement tower. Delivery times will vary depending on your location.

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

If the problem persists, contact support and include: your scanner model (e.g. S100, X2L), a description of exactly when the lights go off (e.g. immediately at scan start, partway through rotation), which troubleshooting steps you completed, and whether Styku Studio showed any error messages or an unstable frame rate.

Applies to: Styku S100 (primarily); general USB and power-saving steps apply to all Styku scanner models.
