3. Check if Non-Thermal Labels Are Used

Thermal printers can only print on thermal labels. If regular labels are used, they won’t react to heat, so the labels will come out blank. If you are not sure if your labels are thermal ones or not, here’s how to check if your labels are thermal:

• Lighter Test: Hold a lighter near the label. If it turns black, it’s thermal paper; if it doesn’t, it’s not.
• Scratch Test: Scratch the surface of the label with your fingernail. If it leaves a black mark, it’s thermal paper; if it doesn’t, it’s not.

4. Check if Label Coating Works

Sometimes, the thermal coating may have quality issues or be uneven, causing blank spots or entirely blank labels. You can print several test print to see if the whole label roll are printing blanck labels. If so ,You can test the coating by using the lighter test mentioned above. If the label doesn’t turn black, it may be defective. In this case, contact your supplier for a replacement or refund.

5. Check If There Is Printer Head Issues

Thermal printers use the print head to heat the thermal paper and create text or images. If the print head is malfunctioning or dirty, it may prevent printing. Here’s how to troubleshoot:

• Check the Print Head: Try printing with different labels. If other labels print fine, the print head is likely okay. If not, it may need replacing.
• Clean the Print Head: Over time, dust or residue can build up on the print head. Use a cotton swab with a bit of alcohol to gently clean it, then let it dry before printing again. Regular cleaning helps maintain print quality and extends the printer’s life.

6. If all above are correct, check your printer by printing a self-test page

① Press FEED (green/red light/biggest) button and hold;

② Release after you hear two or several consecutive beeps.

The printer will print a self-test page.
