  • Patent number: 9268628
    Abstract: An image forming apparatus transmits a log thereof relating to a status detected thereby to a log collection server, and sets a storage period of each transmitted log in the log collection server. The image forming apparatus acquires a total amount of logs thereof stored in the log collection server and a storage period of each log from the log collection server, and deletes the log thereof stored in the log collection server based on the storage period of each log before transmitting a log if a sum total including the total amount and a total amount of logs to be transmitted reaches an upper limit.

  • Patent number: 8732497
    Abstract: An apparatus operates in at least a first mode and a second mode consuming less power than the first mode, and stores information indicating specific data to be responded without shifting from the second mode to the first mode, the data being received from a network during an operation in the second mode. Data received from the network during an operation in the first mode is determined whether to be the specific data indicated by the information stored by a storage unit. When the data is the specific data, a shift from the first mode to the second mode after responding to the received data is faster than when the data is not the specific data.

  • Patent number: 8689057
    Abstract: In a network apparatus for receiving a processing request transmitted from an external apparatus connected thereto via a network, it is detected that processing corresponding to the transmitted processing request has not been performed. If it is detected that the processing corresponding to the transmitted processing request has not been performed, a port number of a request destination of the transmitted processing request is recognized and an application corresponding to the recognized port number is specified as an application of a request destination of the transmitted processing request. Furthermore, it is determined whether the specified application is in an ON or OFF state. If it is detected that the processing corresponding to the transmitted processing request has not been performed and the specified application is in the OFF state, error information including information indicating the specified application is output.

  • Patent number: 8659777
    Abstract: In print systems based on data reception from a server, it takes much time to receive data of a large size. Therefore systems have been developed in which data is divided before being received. However, if divided data items are received by a print device while temperature adjustment or calibration is performed for an engine of the device, the divided data items are not immediately printed, resulting in a long print time. A print device sequentially receives divided data items if the print device is in a printable status. Otherwise, the print device simultaneously receives the divided data items in a plurality of sessions.

  • Patent number: 8453230
    Abstract: A communicating apparatus that is able to perform IP-FAX communication without making the user aware of the attack and without any difficulty, even if the device recognizes a DoS attack or the like. communication that uses a SIP server on a network is performed by a communicating unit. Unauthorized communication from the communication performed by the communicating unit is detected. A port number of a receiving port of the communicating unit is changed when the unauthorized communication is detected. it is determined whether or not the detected unauthorized communication has passed through the SIP server.

  • Patent number: 8428230
    Abstract: A communication apparatus that enables to appropriately perform IP filtering even when communication via a network is performed by a user inputting a destination phone number. An IP filter permits or rejects communication on the basis of a set IP address. An input unit inputs a phone number. An acquisition unit acquires an IP address corresponding to the phone number inputted by the input unit from a server connected to the network. A setting unit sets the IP filter so that communication using the IP address acquired by the acquisition unit is permitted.

  • Patent number: 8214695
    Abstract: To enable the host server side to be aware of the recovery of an error when the error is recovered by the user's power off/on operation, the most recent state regarding occurrences of errors at printer 16 (steps S61 and S62) is stored in the backup RAM 12a each time a status change occurs (steps S63 and S64), and when an user performs a power off/on operation and a printing device is re-activated (step S65), if a most recent state at the time of the previous activation was in a state of service call error occurrence (step S66), the current status of the printer 16 is then sent (steps S68 and S69).

  • Patent number: 8115965
    Abstract: An image processing apparatus which makes it possible to change the manner of authentication between cases where restriction of a specific process is performed on an image of an original, as an original document, and where the restriction of the specific process is performed on an image of an original, as a copy of the original document. A scanner reads an image on an original. An embedded information-extracting section extracts specific information contained in the read image. A determining section determines based on the extracted information whether or not the original is an original document. An authenticating section performs authentication using respective difference pieces of authentication information in cases where the original is determined to be an original document and where the original is not. A copy operation control section restricts the specific process based on the image, according to a result of the authentication.

  • Patent number: 7761470
    Abstract: An information processing method which can reduce stress on the user by always providing services to the user without any delay. The information processing method is executed by an information processing apparatus. A search server is requested to perform a search for at least one of servers for performing desired data processing, and a result of the search showing a first server is received from the search server. The search server is requested to perform a search for at least one of the servers for performing the desired data processing, and a result of the search showing a second server which is different from the first server is received from the search server, when the first server cannot accept a request for performing the desired data processing from the information processing apparatus. The second server is registered in a storage as a substitute server for the first server.
