What is direct thermal printing?

Thermal printing has proven to be extremely useful for a variety of reasons. One of the primary benefits is that no ink or toner is required, making it easier to print on a variety of materials.

This works because the printhead is designed to apply both heat and pressure directly to the surface of the heat-sensitive paper. As a result, the paper is blackened in order to print an image, shape, or text.

However, the printing quality of a thermal printer can be limited by the quality of a print head in many ways. This is why it is important to ensure that you pick the right printer with a high-quality printhead.

 

Common printhead Problems

The thermal printhead is the part that has direct contact with the media and rubs against it and there are some issues that can arise from using these types of printheads. 

The biggest issue with this is that the replacement cost for printheads is high. It is a time-consuming process to replace them and this can be an issue in itself. 

Here are some factors that affect printhead lifespan:

Platen pressure

Excessive pressure causes the printhead assembly to become clogged. Consequently, this would result in the printhead lifespan to be shortened.

Contaminants

Thermal paper is the part that has direct contact with the printhead. It might pass through abrasive materials throught the printhead and cause contamination. Besides, exposed in the dust would also cause slightly pollution to the printhead.

Overheat and high-speed printing

The need for more heat to transfer the image to the paper is going to require that the machine works more than necessary. More heat leads to premature damage of the printhead and this leads to more expenses in a shorter period of time.

 

 

Printhead Maintenance and tips for durability

It is important to find ways to solve these problems in order to be able to achieve the best results. Here are things you can do to extend your printhead's lifespan. 

Appropriate printhead pressure

This is only possible when the machine is optimized for this purpose. The good thing is that a quality printer is always going to be helpful for the purpose of applying appropriate pressure to preserve the printhead.

 

Use high-quality thermal paper

You want to make sure that you can use the highest quality thermal paper in order to ensure that the printhead will work seamlessly. It's recommended to use thermal papers that manufacturers provide.

 

Avoid touching the equipment

You should avoid touching the printhead and this way you will make exposure of thermal label printers and printheads to water, heat, and contaminants minimal. All of these are going to damage the printhead over time. The less you touch the equipment or expose it to elements, the longer it will last.

 

Clean the printhead

Make use of a cleaner or a non-abrasive and reliable cleaner. This is ideal with a cloth that is lint-free and 90% alcohol. The more you do this, the easier it will be for you to increase the lifespan of your printhead.
