The message is that there is a paper jam in the printer paper path. Take out the paper jam first.

If the paper jam still exists, please observe the position of the paper jam.

1 Check whether there is paper jam in the paper tray.

2 Check whether there is paper jam under the toner cartridge.

3 Check whether the paper outlet is jammed. If the heating element has been replaced, it is mainly necessary to check this position.

Make sure to remove all jammed paper, and then print and test it. If the paper jam still occurs, please follow the following methods:

1 If the paper jam position is not fixed, it is usually caused by the paper itself. Replace 80g standard ordinary printing paper for testing.

If the paper jam has been solved, please observe where it is.

A. If it is under the toner cartridge, please replace the original toner cartridge for testing.

B If it is in other locations, such as heating elements, there may be something wrong with this part of the hardware, so you need to contact the local maintenance center. The following is the link to the maintenance center:
