What if the printed label is not clear?

1. Try to choose PDF file format for printing instead of PNG, JPG, and other image formats, when the barcode you print out is very fuzzy (please refer to the picture below).

   

2. Ensure you are using the original power adapter and high-quality thermal label paper (such as Svantto brand), and clean the print head regularly. Please refer to How to maintain the print head for ST425? for the detailed instructions on print head maintaining.
3. If the issue persists, please contact our Technical Support team and include your printed results of your label and the self-test page. If possible, please also provide your original label file and a screenshot of the print preview page so we can review them. We will further determine whether your printer has any hardware defects and proceed with the appropriate warranty service for you.
