With the continuous improvement of people's living standards, thermal paper has become an indispensable part, and the demand for thermal paper is also increasing. However, there are still various problems in the process of use. Then, what is the reason why the thermal paper cannot print words and patterns? Let's take a look together!

Thermal paper is heated by thermal printing paper in a fixed position to render it color and produce corresponding images. Heating is provided by heat sensitive material in contact with the print head. The heater is in the form of arrangement or discharge controlled by the logic of the printer. When driven, a pattern corresponding to the heating element is generated on the thermal paper. The same logic circuits are used to control the heating element, while controlling the paper feed, so that graphics can be printed on the entire label or paper.

Then, the reasons and solutions for thermal paper that cannot print words and patterns

1. Determine whether the purchased thermal paper is a special type of thermistor printing paper. Judging method: scratch the paper with fingernails or sharp objects, and gray marks will appear. It seems to be written on thin paper with a marker pen. If there is an imprint, it means that it is a qualified thermal paper. Otherwise, try to change it.

2. If the thermal paper enters and exits normally, it does not necessarily mean that the working pressure of the drum of the photocopier is normal. When disassembling the copier to check whether the drum is pressed against the surface of the thermal paper, the working pressure of the print head of the printer is completely normal. Whether the pressure roller is in a thermal state when the copier is working.

3. Assuming that the label printer adopts the printing ribbon method, when the copier is working, it is necessary to check whether the printing ribbon can transfer the paper normally, and if it cannot be replaced, try a new one.

4. If the possibility of the above three reasons is ruled out, it is very likely that the printer nozzle of the label printer is broken and cannot be copied during work. It is recommended to disassemble a new one.

Of course, the cleaning and maintenance of the thermistor sticker machine is the key. When the barcode printer has been used for a period of time, the following problems will occur to the printer: the printing is not clear. The longitudinal direction of the printed page is not clear. The noise is loud during printing, and the printer nozzle should be removed.
