The following methods can be used to eliminate and solve the problem: 1. Check whether there is label paper stuck on the machine cover detector or print head, which causes the machine to be unable to detect the paper. 2. Check whether there is a discrepancy between the current template setting size of the APP and the actual size of the label paper. Jingchen label paper comes with a chip to automatically identify the template. Just click on the current template on the page to open and edit it directly, without manually selecting the label template. 3. Please check whether the paper bin baffle is not installed in the machine paper bin, or the paper bin baffle is not installed properly. 4. Excluding the above three situations, if the problem is still not solved, it is preliminarily judged that the detector failure causes continuous paper output. You can contact the online customer service for communication and resolution.

1. The D101 label machine is currently only compatible with D101 series special label paper. Using other brands of label paper will cause it to not work properly. 2. Check whether there is any foreign object in the paper bin blocking the sensor port and causing it to be unable to be recognized. If so, just clean the foreign object in the paper bin. 3. If the above two situations do not solve the problem, it may be that the label chip is temporarily not recognized. You can contact customer service to send the label number, and the after-sales technician will fix the problem for you within 10 minutes.

1. When the machine is charging, the phone will not be able to search for Bluetooth. Unplug the power cord and search and connect. 2. If Bluetooth is slow to respond, restart the software or the machine and try to connect again. 3. If it is caused by software version problems, try uninstalling and reinstalling the software and searching for Bluetooth again. 4. If the above situations fail to solve the problem, you can contact online customer service for processing and resolution.

1. Check whether the machine paper bin has been loaded with label paper. 2. Check whether the paper bin baffle is installed when loading 15mm width paper labels, or whether the paper bin baffle is installed properly. 3. If the above problems are excluded, it is a machine failure, you can contact online customer service for processing.

1. Check whether the label template size set by the software matches the actual label paper size. 2. Check whether there are foreign objects or glue at the machine's paper outlet, and whether the label paper is curled. Clean it accordingly. 3. If the above situation is excluded, it is a detector failure. You can contact the online customer service for communication and processing.

1. Please confirm whether the label paper is the original label paper of Jingchen (the original consumables of Jingchen come with chips). 2. Check whether the actual number of labels printed has exceeded the number specified by the chip. You can double-click the power key to print the self-test page to check it yourself. 3. Excluding the above situation, you can replace the consumables and try to print again to confirm whether the same situation occurs. If so, it is preliminarily determined to be a machine failure. You can contact the online customer service for processing and resolution.

1. Please check whether the Bluetooth system of the mobile phone has crashed. You can restart the mobile phone and restore the Bluetooth in the mobile phone settings. 2. If the problem still occurs after restarting, you can contact the online customer service for processing and resolution.

1. Check whether the label machine cover is closed. You can open and close it several times to see if the error message still appears. 2. If the above situation is excluded, the internal wiring of the machine may be loose due to transportation bumps. This is a machine damage problem. You can contact online customer service for replacement.

In order to ensure the safety of label machines, all Jingchen machines are factory-set with multiple protections. When problems such as "out of paper", "paper bin open", "data error", "ambient temperature is too high", "low battery" etc. occur, the device will terminate printing. Please make judgments based on the actual situation.

1. Please confirm whether the label paper head is exposed from the machine paper outlet during the label paper placement process. You can test the printing again after the label paper head is exposed by 0.5 cm. 2. Check whether the label paper in the machine paper bin has been used up. If so, please replace it with new printing paper.
