QR Troubleshooting
Troubleshoot QR scan failures by separating image problems from destination problems, then check size, contrast, quiet zone, logo, blur, glare, curvature, damage, and print quality.

If a QR code will not scan, first test the original source file. If the source works but the printed version fails, check physical size, contrast, quiet zone, logo size, blur, glare, curvature, damage and print quality. If the camera recognizes the QR but the page fails, fix the destination rather than the QR image.
A QR can fail for many reasons, but most problems fall into four groups:
Start by identifying whether the phone recognizes the QR at all.
The problem is likely:
The QR may be fine.
The destination could be:
That is a destination problem.
A QR that is tiny may work on a high-resolution monitor but fail when printed.
Solution:
Light QR colors can be difficult for cameras.
Solution:
The QR needs clear space around the outside.
If nearby text or design touches the code, detection may suffer.
Solution:
A centered logo can work, but too much coverage can make decoding unreliable.
Solution:
Common causes:
Solution:
Glass, laminate, glossy vinyl, and glossy paper can reflect light.
Solution:
A QR wrapped around a bottle or tube can distort.
Solution:
Scratches, folds, tears, dirt, and fading can affect scanning.
Solution:
A cut edge may remove the quiet zone or part of the QR.
Solution:
If the QR scans but opens:
fix the destination.
If the QR is dynamic, update the saved destination.
If it is static, redirect the original URL if you control it or replace the QR.
Some designs use a transparent QR over photography.
This can destroy contrast.
Solution:
Place the QR inside a clean light box.
Decorative shapes, gradients, colors, and oversized logos can reduce reliability.
Solution:
Simplify.
A QR should be functional first.
If one phone fails but several others work, the issue may be device-specific.
If many phones fail, the QR design or print is more likely the problem.
Go back to the original PNG or SVG.
If the source scans but the printed version does not, the issue was introduced by:
That narrows the troubleshooting quickly.
If the source QR works but the exported brochure or flyer does not, inspect:
If the printed QR scans but the URL is wrong, a dynamic QR can often be fixed without reprinting.
Open the management page, change the destination, save, and scan the printed code again.
A static QR cannot be reprogrammed.
Possible options:
Before printing:
After fixing scanability, make sure the destination is useful on mobile.
A perfect scan leading to a broken or confusing page is still a failed experience.
