Techniques to Ensure Your Thermal Receipt Printer is Functioning Properly


Looking for tips on how to fix your Thermal Printer? A lot of the times the printer is not actually broken but instead, the Thermal Paper is being loaded incorrectly or the wrong paper is being used. There are three steps that may help get you back on track:

1) Verify that the roll is thermal coated paper by scratching the surface of the paper with a coin or nail. If it's Thermal paper, you will get a black mark where you scratched.
2) Verify the thermal paper was loaded correctly and try printing again (see diagram below).
3) Check to be sure you have the correct roll size or core size, too little or too big may cause issues.

Example of proper paper loading:

Still not working? Your thermal printer probably needs a good cleaning. We recommend using Thermal Printer Cleaning Cards and Thermal Printer Cleaning Swabs or Pens with every paper roll change to help remove residue and other contaminants from thermal print heads, paper guides and paper paths.
