Determine printhead failure and optional barcode printhead tips

Guide: When printing labels on a bar code printer, if the surface of the print head is dusty or the printer is worn for long-term printing, you can clean the print head with alcohol or replace the print head.

First, determine whether the print head is disconnected during use

The print head of a bar code printer 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 1MM. It can be seen that the width of the heating element is very small. The phenomenon that the print head is broken is usually easier to judge. Generally, you will find that the printed barcode label has a straight, fixed blank line from top to bottom. Usually the print head is broken, it can't be repaired, only the print head can be replaced, and the price is not cheap.

Second, analyze the main causes of print breaks

- Dust on the surface of the label label paper. For a sophisticated heating unit, small dust can scratch a delicate tissue like a large stone.

- Inferior bar code label paper or the surface of the ribbon is uneven, which is one of the main causes of the broken head of the print head.

- Usually use inferior barcode label paper or ribbon to adjust the temperature of the print head to print clearly, and high temperature is often the cause of the easy break of the print head and shorten the life of the print head.

- Bar code label paper that has fallen off the ground, has been dusty but rolled back to use.

- The width of the ribbon should be slightly wider than the barcode label, because the edge of the barcode label is very sharp and can cut the printhead, so do not use a narrower size than the barcode label to save the ribbon.

- The rubber roller under the print head is not clean and there are many protruding impurities that cause wear on the print head.

- In order to reduce the corrosion of the thermal print head, it is usually possible to wipe the paper dust and toner on the surface of the print head with ethanol or IPA (remember not to touch the surface of the heating element by hand); it is recommended not to have Na ions, K ions. , Cl ion, and the brand reliability and evaluation of the bar code label paper and ribbon; try to avoid the appearance of moisture on the surface of the heating element. In case of moisture, set the voltage to off until the moisture disappears.

Optional Bar Code Printer Note: The most important part is the print head. The print head is composed of a thermoelectric group. The printing process is the process of transferring the toner on the ribbon to the paper by the thermal group heating. Therefore, when purchasing a barcode printer, the print head is a component that deserves special attention. Its cooperation with the ribbon is the soul of the entire printing process. In the current domestic printers, there are two different types of print heads due to brand differences. One is a flat-press type print head, and the entire print head is pressed on a ribbon. This type of print head can accommodate various ribbons. With a wide user base, this type of print head is the most common, widely used in various brands of bar code printers; the other is a floating print head, which is a new type of print head mode, the print head is only pressed at the tip On the ribbon, this kind of print head has higher requirements on the ribbon, but it has the function of saving carbon ribbon, so it is widely used by some large companies with strong technical strength.

When purchasing a barcode printer, choose a trusted merchant to purchase. Since barcode printers are an industrial device, their purchase channels are particularly important relative to other products. Reliable merchants can provide users with comprehensive training and after-sales service.
