A thermal printer’s printhead is very important, but also very fragile. Just to be clear a thermal printhead is not made to last forever. Instead, it should be replaced as and when required like you do with thermal ribbons and labels. However, if you take good care of it and keep up with maintenance, it can work well for a long time.
An Original and compatible thermal printhead constantly interacts with moving parts, such as ribbon, labels, and the platen roller. This is why the quality of these components, directly impacts the lifespan of the printhead.
Factors That Contribute To Printhead Wear And Tear
These are the main reasons why printheads can wear out quickly:
Corrosion
If the printhead comes into contact with corrosive substances, its protective coating can get damaged. This is why you should never use materials not recommended by the manufacturer, or any harsh cleaning agents.
Residue Buildup
When ribbon or media coating builds up on the printhead, it can overheat and fail. However, it can be prevented with regular cleaning.
Printhead Pressure
Too much pressure can cause friction and wear out the printhead faster. Therefore, you should use the right balance of pressure and darkness.
Contamination
When thermal labels touch abrasive materials, it can contaminate the printhead while passing through it. It can damage the protective coating and lead to early failure.
Abrasion
Friction, especially from paper dust, can scratch the printhead’s surface. Therefore, dusting the printhead regularly is a must.
Tips To Avoid Thermal Printhead Issues
Here are some tips that can help you prevent the issues we mentioned before:
You should follow the cleaning and maintenance instructions provided by your thermal printhead manufacturer.
Make sure to use the best thermal media from reputable manufacturers.
Try not to touch the printhead directly. If you must, use materials recommended by the manufacturer and clean the printhead surface afterward.
When your printer is not in use, cover it to protect it from dust and other contaminants.
Final Words
Extending the lifespan of thermal printheads is essential for maximizing their efficiency and cost-effectiveness. By following the tips given in this post, you can prolong the life of your thermal printhead. Additionally, conducting routine maintenance checks ensures smooth operation and longevity.
