Thermal Paper on POS Can't Type? Maybe All of These Reasons!

Thermal paper is also known as thermal fax paper, thermal record paper, and thermal copy paper. In Taiwan, it is called thermal copy paper. Thermal paper is a kind of processing paper, its manufacturing principle is to coat a layer of "thermal paint" (thermochromic layer) on high-quality base paper. It can print without cartridge. It can image by heating the thermal paper with a high-temperature printing head. The cost of consumables and installation is low. So it has been well used and promoted.

Thermosensitive printing paper can be printed by heating. Why can't you type a small note? When POS thermal paper can't type, where should I check it?

1. Check thermal paper. The POS thermal paper must be used in thermal pos, and thermal paper can be printed only on the smooth side. If installed in reverse, it can not print out the words. Here's a little trick, with a little fingernail stroke, leaving a black scratch is the thermal paper can print the side. In addition, the thermal paper also has a shelf life, it is better to know clearly before buying, once it expires, it will also lead to typing out, to judge whether it expires or not, also with sharp items, no color is expired. However, we can generally ignore the issue of the shelf life because the thermal paper shelf life is 35 years old! So consumers can rest assured.

2. Check the print head. Thermosensitive printer head must produce a high temperature in order to make thermal paper imaging. At this time, do not touch the thermal head directly with your hand, otherwise, it is easy to burn. To determine whether the thermosensitive print head is a problem, you can see whether the printed ticket is blurred or not. If it is, it is usually stained by the thermosensitive head. You can wipe it lightly with an alcohol sponge. If it is still blurred, you need to replace the thermosensitive film.

3. Check the drum of POS machine. When printing, we need to press the thermal paper firmly with the help of the drum. If the drum is loose, it will lead to poor contact between the thermal paper needle and the thermal paper and cannot type. Then try pulling down the printing paper to check whether the drum is loose.

As long as you check from these places, you can get rid of the problem that most POS thermal papers can't print words. Have you learned?
