After cleaning the print head and replacing the thermal paper with high-quality one, the print is still unclear. What should you do next? If the print quality remains poor, it might be an issue with the printer’s internal components. Follow these steps carefully to troubleshoot: 1. Open the upper cover of the printer and remove the rubber roller. This will allow better access to the print area. 2. Insert the thermal paper into the printer as shown in the diagram. Make sure it is properly aligned and seated in the paper guide. Double-check that the paper is not curled or damaged. 3. Reinstall the rubber roller onto the print head. Ensure it is securely in place and positioned correctly to apply even pressure during printing. 4. Once everything is reassembled, print a self-test page to check the print quality. If the text is still blurry or incomplete, the issue may be with the print head itself. If the print is still not clear after following these steps, the printhead could be damaged. In that case, it's recommended to replace the print head as soon as possible to avoid further issues.
