3.8 ERROR LIST

3.8 ERROR MESSAGES: When the machine has encounters a problem with one of it's components
it will give the end user an error message. Technicians can check the list of errors the machine has
encountered and the number of cycles the machine had performed when the error occurred. SEE PAGE
18 OF THIS SECTION FOR MORE DETAILS ON HOW TO ACCESS THE ERROR LIST.
