Camera, QR scanner or printer not working
How to fix the most common issues with the camera, batch scanner and connected Brother printer.
The camera, scanner and printers are the devices used most during service, so they are also the most exposed to small permission or connection issues. Most of them are fixed in a few steps without needing technical support.
The camera does not open
If the app asks for camera access and nothing happens, the permission was likely denied in the device settings. It needs to be re-enabled manually, because the app cannot force it after an initial refusal.
The QR scanner does not read the code
A damaged, too small or glare-affected QR code is the most common cause of a failed scan. Moving the device slightly, cleaning the lens and improving the light on the label often fixes it without reprinting.
- Clean the camera lens
- Move the device slightly closer or further from the code
- Avoid direct light glare on the label
The Brother printer does not print
If the printer does not respond, first check that it is on and connected to the same network as the device sending the print command. A jammed label in the roll or an empty roll are the most common causes after checking the network.
Print queue stuck
If several labels stay pending, a stuck job in the queue can block the following ones. Cancelling the single stuck job usually clears the queue without needing to restart the printer.

Passaggi
- Check in the device settings that the app has camera permission enabled.
- If the scanner does not read, clean the lens and improve the light on the label.
- Check that the printer is on and on the same Wi-Fi network as the device.
- Check that there is paper or labels in the printer roll.
- Open the print queue and identify any stuck jobs.
- Cancel the stuck job and try printing again.
- If the problem remains, restart the printer and repeat the print.
Problemi frequenti
- The camera does not open at all → the permission was denied previously → re-enable it from the device settings, not from the app.
- The scanner reads a different code than the one framed → several QR codes too close together in the same shot → frame only one code at a time.
- The printer shows as connected but prints nothing → a previous job stayed stuck in the queue → cancel it and try again.
- The printed label is cut in half → the label template does not match the loaded roll → check the template format before reprinting.
Domande frequenti
Why does the camera work in other apps but not in Klyra?
Camera permission is granted per app: check in the device settings that it is specifically enabled for Klyra.
Do I need a specific printer for Klyra?
Klyra is designed for the compatible Brother printers listed in the labels section; other models may not connect correctly.
How do I know if the issue is the printer or the network?
Try printing from another device on the same network: if it works, the issue is with the original device, not the printer.
