A non-transitory storage medium stores a plurality of instructions readable by a computer of an information processing apparatus. The information processing apparatus comprises a communication interface for connecting to a scanner. The information processing apparatus includes a first route and a second route. When executed by the computer, the plurality of instructions cause the information processing apparatus to execute a scan control using the first route in which a read result of a document by the scanner is obtained by using the first route after receiving an execution instruction for scanning, determine whether the scan control using the first route has failed or not, and execute a scan control using the second route in which the read result of the document by the scanner is obtained by using the second route when it is determined that the scan control using the first route has failed.

A print management unit attaches an identifier to print data that goes through a custom processing unit functioning by execution of a custom class driver, and delivers the print data with the identifier attached, to a standard print control unit. The custom processing unit deletes the identifier from the print data delivered from the standard print control unit and customizes processing of causing a printer to execute printing, based on the print data. The print management unit detects a read state of the custom class driver by execution of an OS. When the read state indicates a failure in reading the custom class driver, the print management unit delivers the print data without the identifier attached, to the standard print control unit, and thus causes the printer to execute the printing that is limited via a standard communication control unit or to stop the printing.

A server apparatus receives setting information that indicates settings of an information processing apparatus, and obtains a default setting for each of a plurality of particular setting items that are related to security among a plurality of setting items in the information processing apparatus. The server apparatus detects, based on the setting information, whether or not a setting of each of the plurality of particular setting items has been changed from the default setting, and notifies a user of a detection result in a case where it has been detected that none of the settings of the plurality of particular setting items has been changed from the default setting.

An information processing apparatus includes, a reception unit configured to receive an instruction to transfer the information processing apparatus to the second power state, an analysis unit configured, when the reception unit receives the instruction, to analyze a factor limiting the transfer of the information processing apparatus to the second power state, and a control unit configured, when the analysis unit analyzes the factor and as a result the factor is a first factor, to control the information processing apparatus to transfer to the third power state without waiting until the factor is resolved, and configured, when the factor is a second factor, to control the information processing apparatus to wait until the factor is resolved, and to transfer to the second power state.

A method of detecting fraudulent use of a printing device including a non-contact memory tag, including receiving a request to read the tag, receiving information from the tag, determining an installed configuration of the printing device from the information, comparing the installed configuration to a current configuration of the printing device, and in response to determining that the current configuration is not the same as the installed configuration, indicating that a violation exists.

An image forming apparatus and method for determining a response delay time for maintaining a long polling connection are provided. In an example, the image forming apparatus includes a communication device to communicate with an external device, a processor, and a memory storing instructions executable by the processor. The processor may execute the instructions to request the external device for a response about whether a job to be performed by the image forming apparatus is present based on a response delay time for long polling the external device by the image forming apparatus. The processor may also execute the instructions to detect an error from the response, adjust the response delay time, and determine a final response delay time for maintaining connection of the long polling by re-adjusting the adjusted response delay time based on a result of performing the long polling based on the adjusted response delay time.

An image forming device includes a communicator that receives a series of image data, a timer that measures a reception time of each of the series of image data, and a storage that temporarily stores the image data received before forming an image based on the series of image data. When the communicator receives image data, and subsequently does not receive the next image data within a predetermined reception time, the controller obtains the time difference between the time of the reception end of the series of image data, and the reception time of the image data last received by the communicator, determines that the last received image data may be incomplete image data when the time difference is greater than or equal to a predetermined time, and determines whether to form an image based on the image data stored in the storage according to the determination.

An information processing apparatus includes an acquisition unit, a power supply unit, and a controller. The acquisition unit acquires failure information for the information processing apparatus via a wireless communication line from a management apparatus holding failure information. The power supply unit supplies power to the acquisition unit when the main power supply is not on. The controller exerts control in such a manner that, when the acquisition unit acquires the failure information from the management apparatus in the state in which the main power supply is not on, only a subset of functions of the apparatus are activated by supplying power from the power supply unit, and a process for limiting use of a function related to the failure is performed.
