The printhead is the most expensive and fragile part of a bar code printer component, and its quality directly affects print quality.
The print head can't just calculate the warranty according to the time. Many customers will be confused about this. Because the print head is a fragile lossy product, it is easy to be affected by the external environment, so it is usually not calculated in terms of time. If it is necessary to press time, The premise of it is that there is no physical damage, and it is very important for everyone to pay attention to this.
The life of the printhead is not calculated in terms of the length of time. What is the standard?
In fact, the print head is very similar to the tire. The print head is calculated by the print length. The print head reference given by the manufacturer has a normal service life of about 30 kilometers.
Bar code print head damage mainly comes from the wear caused by high-speed printing, high temperature environment makes thermal paper (thermal bar code printer) or ribbon (thermal transfer label printer) dirty print head, high pressure or static caused by print head crack And deformation. Once the print head is damaged, there are white lines in the printed label, and the printed label is blurred, and the reader cannot read the data.
Use a printhead-specific cleaning film to save the printhead
A printhead cleaning blade has been specially developed for printhead cleaning. The printhead cleaning blade is a special film film that removes dirt deposits on the printhead without damaging the printhead.
There are many advantages to using a rescue printhead to clean the film: in addition to extending the life of the printhead, it also reduces the downtime required for maintenance and saves the cost of replacing the printhead. Therefore, it is an economical, convenient and quick way to remove dirt and dirt without the need to remove the print head.
Operation method:
1) The power of the barcode printer must first be disconnected.
2) Then turn on the printhead to remove the print media and print ribbon from the print unit.
3) Clean the printhead according to the recommended printhead maintenance procedures.
4) Place the rescue printhead film on the print path under the printhead with the smooth side down and the matte side up under the printhead.
5) Close and lock the print head.
6) Slowly withdraw the film completely from the printing device.
7) Clean the printhead again in accordance with the recommended printhead maintenance procedures.
8) Load the print media and ribbon, close and lock the printhead.
9) Print multiple labels to check if the print quality has improved. If the print quality does not improve, please contact technical support.
In addition, we need to pay attention to the use of print head film to remove dirt and dirt only once, and each film can be used up to ten times, can not always use the same print head film, and, when on the print head film We should discard such film when there is significant residue or dirt.
A well-maintained printhead can be very durable and can be used for more than 2 years. If the printing effect is not good, there is a need to print, the needle is broken, etc., and a new print head needs to be replaced.
The printing consumables are in direct contact with the print head, so the quality requirements of the consumables must not be evaluated only by price. Otherwise, because the cheap label paper hurts the expensive print head, it will not be worth the loss. After professional testing, the meager expenses required for regular maintenance and maintenance of the print head can save several times or even dozens of equipment repair or renewal costs.
