That error occurs when a stapler jam has already happened and then happens again. The stapler jam is usually a detection failure, and it may involve a motor being non-functional.
To be more specific, would require your looking into the stapler, and finding whether there is a real jam, and whether the motor is indeed non-functional. If this requires disassembly, you would indeed need a service tech to do the work, even just to determine what is wrong exactly.
