Troubleshooting

The Troubleshooting section helps resolve common issues that may arise during the setup, calibration, or scanning process with the DMIx SamplR. Follow these solutions to ensure uninterrupted operation.

Issue	Cause	Solution
SamplR not powering on	Power adapter or USB-C cables not connected properly. Unsupported power supply.	Check both USB-C cables and ensure they are securely connected to the power adapter and the SamplR unit. Test the power outlet with another device. Confirm the power supply supports DMIx SamplR (minimum 45W with a 15V power lane).
iPhone not charging	Pre-connected USB-C cable is loose or damaged.	Test the iPhone on another power supply. Contact support.
Cannot connect to DMIx SamplR	Bluetooth is disabled on the iPhone. SamplR app lacks Bluetooth access.	Enable Bluetooth on the iPhone. Allow Bluetooth access via iOS settings (Settings → Apps → DMIx SamplR).
Unable to start calibration	No device connected.	Connect to DMIx SamplR.
Calibration failed	SamplR app lacks camera access.	Allow camera access via iOS settings (Settings → Apps → DMIx SamplR).
Inconsistent results	Environmental factors (e.g., lighting changes) or dirty calibration paper.	Recalibrate in a controlled environment with minimal external interference.
Blurry, unsharp results	Sample is not in focus or improperly placed. Dirt, smudges, or dust on iPhone camera lens or polarisation filter. Sample moved while scanning.	Toggle preview light and adjust focus using the app slider until the material is sharp. Ensure the material lies flat and is correctly centered in the scanner. Clean camera lens and/or polarisation filter. Use magnets to secure small or lightweight materials on the scanner’s surface.
Scan was not uploaded	Unstable Wi-Fi connection or platform access issues.	Verify that the iPhone is connected to a stable Wi-Fi network. Confirm that the DMIx platform is accessible, and your account has the necessary permissions.
Unable to Move Scans to Collections	Collection is not pre-created, or the user lacks edit rights.	Confirm that the collection exists in the DMIx platform before attempting to move scans. Ensure your user account has the appropriate edit permissions for the desired collection.
Phone Adapter Not Secured	Adapter is loose or improperly installed.	Follow the separate installation instructions provided with the SamplR Phone Adapter. Tighten the adapter securely but avoid over-tightening.
