I have a machine with a hopper that does not do anything, can someone explain to me how the hopper works? Is there an optical eye that tells when the hopper has enough tokens to pay out? What tells the motor to spin? What are the two switches near the motor ahd how are they activated? I don`t know the manufactuer but if someone could give me a hint on how to find it I would appreciate it. I could shoe a picture of it if that would help.
