The cash register system plays an absolutely important position in a supermarket. If the cash register goes on strike, the entire supermarket will not operate normally Up. However, in your daily life, do you often encounter situations where the cashier does not issue an order at checkout? As a professional, I will chat with you today, the possible reasons for the trouble.

Generally speaking, there are two reasons why the cash register does not issue an order. One is the problem of thermal paper, and the other is the problem of thermal printer. Let's discuss these two problems!

What could be the problem with thermal paper?

Generally, the printing does not show color. How to solve this problem?

First of all, confirm whether the purchased thermal paper is a special thermal printer paper.

Judgment method: scratch the paper with a nail or sharp object, and there will be black marks, as if writing on a white paper with a pencil and sliding on white paper. If there are marks, it means that the thermal paper can be purchased, otherwise try to change Kind of thermal paper.

The details may not be printed because the roller is not pressed against the surface of the thermal paper when the printer is working. If the thermal paper enters and exits normally, it does not necessarily mean that the pressure of the printer roller is normal. Disassemble the thermal printer and check whether the roller is pressed against the thermal paper surface when the printer is working. If the print head cannot touch the thermal paper, it will not help. It will not print out the handwriting.

Both of these situations are related to the printing paper, so how can the printer affect the printing of thermal receipts?

In fact, the key lies in the type of printer. If the thermal printer is in the form of ribbon, it is necessary to check whether the ribbon can transfer normally when the printer is working. If not, try a new one.
