Why does my S100 sensor keep showing a red ring error even after troubleshooting?

⚠️ The Styku S100 with Kinect camera is end-of-life. This article is preserved for existing S100 customers troubleshooting their current scanner. Styku no longer provides setup support for the S100, and new S100 deployments are not supported. To discuss upgrading to a current Styku scanner (X2L), submit a request through the Styku Business Portal at styku.com/portal — a sales representative will be assigned and reach out to you.

If your S100 scanner's camera sensor cannot be detected and continues to show a red ring error after all troubleshooting steps, the hardware itself may be defective. When this happens, Styku Support will issue a prepaid return shipping label so the unit can be replaced under warranty.

What the Red Ring Error Means

A red ring indicator on your S100 scanner means the camera sensor is not working correctly. In most cases, this is caused by something in the environment or software — but sometimes the sensor itself has failed internally and cannot be fixed remotely.

Troubleshooting Steps Support Will Try First

Before determining that a hardware return is needed, Styku Support will typically walk you through the following steps:

1. Adjust the environment — Turn off all lights, close window blinds, and shut any doors to eliminate daylight or ambient light interference.
2. Reposition the scanner — Tilt or reposition the camera tower slightly and confirm it is 25 inches away from the turntable, with at least 14 inches between the turntable and any side or back walls (18 inches of clearance around the turntable is recommended).
3. Clean the camera lens — Gently wipe the lens on the camera tower with a clean, dry cloth.
4. Reinstall the Styku Studio software — Uninstall and reinstall the current version of Styku Studio to rule out a software or driver issue.

When Hardware Replacement Is Required

If all of the above steps fail to resolve the red ring error, the sensor failure is likely hardware-rooted. Support will confirm this determination and take the following actions:

• Issue a prepaid return shipping label via email for you to send back the defective unit
• Pause your Styku subscription so you are not billed while your scanner is out of service
• Process any applicable refund for charges during the affected period
• Ship a replacement scanner once the return is received and processed

This process is covered under Styku's hardware warranty.

What to Expect After You Ship the Unit Back

Once Styku receives your defective scanner, the support team will contact you to confirm the replacement is on its way. When your replacement unit arrives, set it up following the instructions in your user guide and contact support if you need help getting started again.

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

If the problem persists, contact support and include: your business location name or license key, a description of all troubleshooting steps already attempted, the date the red ring error first appeared, and whether the issue started after a recent software update.
