6, the working process of the copier is generally as follows: When the copy command is not in idle state, once received a copy of the command to enter the state of the copy, complete a copy of the operation of the specified work and then back to idle state, waiting for the next copy of the command; After filling the paper into idle state, ready to receive the Copy command, if a paper jam failure occurs when copying, enter the paper jam status, issue a warning waiting for the maintenance personnel to troubleshoot, and then return to the idle state after troubleshooting. Describe the behavior of the copier using a state transition diagram.    

For:
