If the printer feeds paper but the receipts are blank, the paper roll may be loaded incorrectly. Because the printer is mounted upside down inside the kiosk, it is easy to install the paper in the wrong orientation.
Troubleshooting
1. Remove the paper roll.
Open the printer and remove the receipt paper.
2. Check the paper.
Thermal printers do not use ink or toner. Make sure you are using thermal receipt paper and that the paper is not damaged.
To test the paper, scratch the shiny side with your fingernail.
- ✅ A dark black mark appears: the paper is working correctly.
- ❌ No mark or a light gray mark appears: replace the paper roll.
3. Reload the paper.
Reload the paper as shown below. If needed, flip the paper roll to ensure it is installed in the correct orientation. Make sure the printer cover is fully closed.
4. Print a test receipt.
Print a test receipt.
- If the receipt prints correctly, the issue has been resolved.
- If the receipt is still blank, continue to the next step.
5. Restart the printer.
Turn the printer off, wait about 30 seconds, then turn it back on. Print another test receipt.
6. Still having the issue?
If the printer is still printing blank receipts after completing these steps, the issue is likely related to the printer hardware. Further inspection or replacement may be required.
