Basically, it has only sendingfunction, and the conventional receiving/forwarding function is used for receiving.As for sending, there is correlation between the communication management report of theMain Device and that of the Sub Device.As for receiving, the conventional fax receiving/forwarding function is used, so there is nocorrelation between them.Sending:As for sending operation, the log of the Main Device and that of the Sub Device are basicallythe same, and the same logs are stored in both of them.The Main Device can be connected with more than one Sub Device. In that case, all the joblogs are stored the Main Device, and only the logs of jobs sent by the Sub Device itself arestored in each Sub Device.However, if sending from the Sub Device to the Main Device ended in failure, the relationbetween them is lost when the network with the Sub Device goes wrong while the MainDevice is sending the fax.F-4-4F-4-4
