The print head of a bar code printer is one of the most important components in a bar code printer. It is a consumable item and has a typical life of about one year (depending on the frequency of printing). Common bar code printers have 8 or 12 heating elements in the printhead 1MM length, and the width of the heating element inside is very small. After the print head is broken, it will seriously affect the scanning effect of the bar code. The print head should be replaced in time after the needle is broken.
When judging whether the print head is broken, you will find that there is a straight, fixed blank line on the printed label paper from top to bottom. If a long blank line appears on the label paper, the print head is broken. Generally, the print head is broken and cannot be repaired. Only the print head can be replaced.
The general causes of print breaks are:
1. Dust on the surface of the label paper;
2. Inferior label paper or ribbon surface is uneven;
3, usually use inferior label paper or ribbon to increase the temperature of the print head, in order to print clearly, and high temperature is often the cause of the print head easy to break the line and shorten the life of the print head;
4, the label paper dropped on the ground, has been dusty but rewinded back to use;
5, the width of the ribbon should be slightly wider than the label paper, because the edge of the label paper is very sharp will cut the print head, so do not use a narrower size than the label paper to save the ribbon;
6. The rubber roller under the print head of the barcode printer is not clean, and there are many protruding impurities causing wear on the print head. Under normal circumstances, the above problems will cause the print head to be damaged. Therefore, be careful when using it. Because the print head is broken, the label cannot be printed, and replacing a print head can be several hundred to thousands.
7. Static electricity will only break through the print head and cause the print head to break.
