How to Clean a Thermal Printhead?

Home/Paper Knowledge/How to Clean a Thermal Printhead?

PrintHead is an essentical part of a thermal printer. With the heated printhead, text/image is created on surface of thermal paper. If the printhead is broke, the printer can not work well. If it is broke, it will create nothing on the paper.  If the printhead becomes dirty and sticked with glue, it can’t create clear image. This will affect the print image and customer user experience.

Where is the PrintHead?

Open the printer cover, see inside clearly. Find a smooth black bar near the paper exit. See picture below.

It’s better to buy a Thermal Printer Cleaning Pen to clean the print head. If you don’t have the pen around, you can gently clean it through a soft cloth with alcohol. Be sure to turn off the printer when you clean it.

The daily routine is to clean the printhead once the roll runs out.
