Error Handling in MFP Communication Systems

The patent extracts the error handling function from the general error information distribution system. When error information is distributed to user terminal devices, the system identifies which device should handle the error and excludes other devices from handling actions. This allows error information to be widely distributed for awareness while preventing redundant handling attempts by unauthorized devices.

The patent introduces an intermediary mechanism (the error handling permission system) between error information distribution and error handling execution. The communication device acts as a mediator that receives error information, determines the appropriate handling device, and grants permission accordingly. This intermediary layer prevents direct handling by all receiving devices, resolving the contradiction between information distribution and handling efficiency.

The patent applies local quality by assigning different roles to different user terminal devices based on their characteristics or current state. Instead of treating all devices equally, the system identifies specific devices with appropriate qualities (e.g., user presence, device capabilities) to handle errors, while other devices receive only notification. This prevents redundant attendance while maintaining reliable error resolution.

The patent implements preliminary action by pre-determining which user terminal device should handle errors before the error handling process begins. The communication device identifies the appropriate handling device in advance and grants permission proactively. This preliminary assignment prevents multiple users from simultaneously attempting to handle the same error, eliminating redundant attendance while ensuring reliable resolution.
