Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 158 words
An image forming apparatus controlled by a centralized control unit located at a remote site, via a communication network, comprising: a message display; a communication device which is connected with said communication network to call said centralized control unit and to transmit information related to said image forming apparatus to said centralized control unit; a memory which stores a plurality of messages corresponding to states of communication between said communication device and said centralized control unit; and a controller which determines that said image forming apparatus has attained a predetermined calling condition and activates said communication device to call said centralized control unit in response to a determination result; said controller monitoring a state of communication between said communication device and said centralized control unit after activating said communication device, selecting one of said plurality of messages stored in said memory according to the monitored state of communication and causing said message display to display the selected message.
Claim 2
Dependent Claim 158 words
An image forming apparatus controlled by a centralized control unit located at a remote site, via a communication network, comprising: a message display; a communication device which is connected with said communication network to call said centralized control unit and to transmit information related to said image forming apparatus to said centralized control unit; a memory which stores a plurality of messages corresponding to states of communication between said communication device and said centralized control unit; and a controller which determines that said image forming apparatus has attained a predetermined calling condition and activates said communication device to call said centralized control unit in response to a determination result; said controller monitoring a state of communication between said communication device and said centralized control unit after activating said communication device, selecting one of said plurality of messages stored in said memory according to the monitored state of communication and causing said message display to display the selected message.
Claim 3
Dependent Claim 18 words
