1, paper problems. First of all, look at the placement of the paper roll. Some papers are too light to cause paper jams, or in the south, the paper is easily damp and can cause paper breaks. In addition, we can open the printer cover of the cash register machine and pull out the paper roll. Inferior paper is often easy to leave paper scraps, easy to jam the pickup roller, and clean the debris inside.
2, the problem of parts. Excessive use of the cash register will also cause the cash register printer to jam, especially the wear of the pickup roller. It is recommended that we use a printer to wipe it with a damp cloth and an alcohol swab regularly, and then wipe it with a dry cloth. (This depends on whether the actual printer is allowed to touch a small amount of alcohol). Also pay attention to some cash register machine printers. If the printer is turned on for a long time, it will overheat. At this time, the printer will print slowly or jam. It is recommended to wait for the cash register to cool before printing.
3. Set the problem. Some software will automatically set the size of the printed paper. If the actual printed paper does not match the setting, a paper jam will occur. Sometimes all aspects have been checked, but there is still a paper jam. It may be that the memory is full. It is recommended to clean the cash register memory regularly.
