There are a lot of problems with cashiers, and supermarket cashier printers have three most common situations: print blur, half of the prints, and blank prints. First, the printing blur is caused by two reasons, one is that the thermal head is damaged, and the other is caused by the texture of the printing paper. In this case, you can check the printing paper first, replace the other printing paper, and purchase the printing paper to purchase a paper with smooth texture, no impurities, and good flexibility. If it is not possible to replace the paper, it is that the thermal head is damaged and needs to be returned to the factory for replacement.
Secondly, the printer prints only half of the printed characters, which is also caused by the damage of the thermal head. At this time, it needs to be returned to the factory for replacement. Finally, the blank print is also related to the thermal head. First check if the thermal head is deformed and whether it is stuck in the original position. If it is tilted or deformed, it will cause the paper to be inaccessible and cause blank printing. If everything is normal, then the thermal head is damaged and can only be returned to the factory for replacement. Therefore, it is very important to choose a professional cash register cash register supplier.
