You must post pic of what is showing in Init and Dynamic errors that you'll find in the service (WRENCH icon) displays. #15 denotes an error within the main electrical cabinet.

 

Hi sir , give me the sek init test

 

Hello guys, problem solved, it was the magnet on the side of the machine that is on the perfector door covers, and the lost sheet door covers, they have passers that must match 100% for the magnet to work. Otherwise, among the errors, the mark "SEK" was shown on the monitor above the sketch of the main electrical cabinet.

 

Yes this magnet give this error code ,you can know this problem on the sek input-output

Good luck
