Bar code printer head break condition
The printhead of a bar code printer is one of the most important components in a bar code printer. It is a combination of a row of heating elements. The common bar code printer has 8 or 12 heating elements in the length of the print head. The width of the heating element is very small.
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 adjust the temperature of the print head to be clear, and high temperature is often the cause of the easy break of the print head and shorten the life of the print head.
4. The label paper that has fallen off the ground is dusty but rolled back for 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 and 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, so be careful when using it, because the print head is broken, the label cannot be printed, and replacing a print head can be hundreds to thousands.
