Introduction of Thermal Barcode Printer Head
The thermal print head is the most precise component with a complex structure. It plays a key role in the printing process and requires regular cleaning and maintenance during use.
There is a row of rectangular heating units on the print head.By controlling the heat generated by each unit, the print head can print out corresponding graphics, text or barcodes.
The print head is usually installed on the print head bracket and connected to the motherboard, which includes power cables and data cables.
The power cable and data cable of some print heads are combined into one and connected to the motherboard through the same connection cable.
The print head prints text and content on the label through a physical reaction of heating to form a recognizable barcode image.
During the printing process, the heating degree of the heating unit is controlled to achieve precise printing results.

What is the Resolution of a Thermal Print Head?
The density of heating dots on the TPH determines the printing resolution. It's measured in dots per inch (DPI), and determines the sharpness and clarity of printed barcodes and labels. Higher DPI translates to finer detail and more precise printing.
Common DPI options include:
203 DPI: Ideal for standard shipping labels, larger barcodes, and basic text.
300 DPI: Suitable for most label sizes, small fonts, intricate barcodes, and graphics, such as fabric tags, jewelry labels, and asset tags.
600 DPI: Best for high-resolution images, fine lines, and small, complex barcodes, such as PCB QR codes.
Construction Of The Thermal Printhead
- The thermal printheads is an electronic part. On one line there are many dots (heating elements) The more dots per mm, the better the printquality.
- 8dot/200dpi means: the printhead has 8 dot per mm. The printheadresolution is equal to 200DPI (dots per inch).
- 12dot/300dpi means: the printhead has 12 dots per mm. The printheadresolution is equal to 300DPI (dots per inch).
- 200 and 300DPI are standard resolutions in industry and trading envorinment, however currently there are also already printers with 400 and 600dpi.
- The thermal printhead is the most sensitive and vunerable part of the thermal printer, and mostly also the most expensive part of the printer. Besides that the thermal printhead is a wearing part, and his lifespan is among others depending of his maintenance.
- In practice there always excist pollution on the printhead which is easy and necessary to be cleaned up.
- This pollution are residues of paper, glue, thermal transfer ribbon but also other environmental pollutions.
- Pollutions on the printhead are causing bad printquality and temperature deviations which can damage the printdots.

What are Signs of a Failing Printhead?
Typically, you'll know your printhead is failing when you see the following symptoms:
Printed images look faded or lighter
Streaks or bands appear across the labels
Portions fail to print, leaving behind white voids or missing text
If you already experience these issues, it's likely time for a new printhead. Next time, you can prevent a failing printhead by understanding why it happens in the first place.
How to Keep Your Thermal Printer Printhead Healthy?
Corrosion
Your printhead's protective coating can become damaged if substances which contact it are themselves corrosive. To prevent this, avoid physically touching the printhead surface itself; printing on substrates or media that are not recommended by the printhead or label manufacturer; or using cleaning agents that aren't specified by the printhead manufacturer.
Contamination
When thermal labels or other media come in contact with abrasive materials and then pass through the printhead, they can cause contamination. As a result, this can scrape or cut through the printhead's protective coating and lead to premature failure. Again, it's wise to consult with the printhead and/or thermal label supplier up front to determine the proper materials for use with your printhead.
Abrasion
Abrasion is most often caused by friction. In particular, paper dust can collect on the platen toward the outer edges of the media or ribbon and, in turn, abrade the printhead glaze. To minimize it, you can regularly clean paper dust buildup on the printhead as per manufacturer instructions. You should also keep sharp objects (e.g., razor blades, screwdrivers, knives) away from printheads to avoid scratching the delicate surface.
Residue buildup
Buildup of thermal ribbon or media coating on the printhead can cause overheating and eventual failure. While the volume of residue can vary based on label media, ribbons and external conditions, it's important to make sure you institute proper and regular cleaning and maintenance.
Printhead pressure
Related to abrasion, excessive pressure increases friction on the printhead assembly. This, in turn, can cause wear and tear and ultimately, premature failure. To avoid this, utilize a balance of darkness and pressure.
Electrostatic discharge
Characterized by a sudden, unexpected electrical flow between two electrically charged objects, electrostatic discharge can cause significant damage to a printhead's internal circuitry. Factors that often lead to electrostatic discharge include static buildup and non-specified or improper maintenance. To minimize this, work to ensure that any static brushes and/or printhead mechanism wiring are properly secured.
Environmental factors
The environment in which your printer (and by extension, your printhead) operates plays a role in how long that printhead can last over time. Additionally, the area in which label media and ribbons are stored can cause printhead damage. In both cases, it's wise to minimize exposure of thermal label printers and printheads to water, excessive temperatures and external contaminants. An established and leading label converter can consult with you on additional operational and storage strategies for your facility.

How We Make Our Thermal Printheads Highly Reliable?
Energy Resistance
Energy resistance refers to the durability of the heater under the energy conditions which drive the thermal printheads. Kyocera has a structure and process to improve energy resistance.
Abrasion Resistance
Thermal printheads can be used together with a printing media such as thermal paper or ink ribbon. Since the printing is done by directly touching thermal paper or ink ribbon, the surface will be worn out during the printing, especially for industrial barcode printers at high speeds. Abrasion resistance is an important requirement factor that affects the life of printers because improved oil resistance and scratching resistance performance for media are also required. Kyocera has a lineup of overcoats that meet various required performances.
Environmental Resistance
In recent years, thermal printheads have become more and more familiar and closer to our daily lives. For example, ticket machines at parking lots. Thermal printers are used in a places exposed to wind, rain, and other harsh conditions for printers. Therefor, high environmental resistance is required as an important factor.
