E010 A specific revolution is not detected from the main motor rotation detection signal (MLOK*), causing the signal to go ‘1’ (main motor fault) Possible cause: The main motor (M101) is faulty. The controller PCB is faulty.
My guess is that because you lacked the initiative to find the information here - then you will probably not have the initiative to personally fix the copier - and will need to call a service agent.
Good luck...
