It is important to note that when paper is been reloaded , we should make sure to use the paper suited for printing and load it correctly. If the error still persists on the LCD of the machine, there might be a paper that has remained inside the machine. To avoid that, make sure no paper remains in the machine.
If you are unable to remove the paper inside the machine, or if the paper jam error continues even after removing the paper then you should contact the Brother printer customer care phone number or Brother printer number.
