Abstract: A user terminal 1, which is communicably connected to a server device 2 via a network 9, includes: an information acquisition unit 101 that acquires terminal information including a terminal ID of the user terminal 1, and acquires peripheral device information including a device type and a serial number of a peripheral device 3 connected to the user terminal 1 via an interface 15 for peripheral device connection, which is different from a network interface 16 connected to the network 9; and a transmission/reception unit 102 that transmits the terminal information and the peripheral device information to the server device 2.

Abstract: There is provided an information processing system including: a client terminal; and a management server that manages the client terminal, wherein: the client terminal includes a transmission section that transmits notification data containing information denoting an operation state of at least an own machine; and the management server includes: a reply section that sends back reply information in return for notification data from the client terminal; and an information insertion section that inserts task information about a task of the client terminal into the reply information.

Abstract: There is provided an information processing system comprising: an information processing device; and a terminal management device that manages the information processing device, wherein: the information processing device has: a transmission section that transmits notification data denoting at least an operating state to the terminal management device; and a switch section that switches a notification destination of the notification data transmitted from the transmission section, based on return information for the notification data; and the terminal management device has: a return section that sends back the return information in response to the notification data transmitted from the information processing device; and a notification destination information insertion section that inserts notification destination change information for changing the notification destination of the notification data into the return information sent back by the return section.

Abstract: An image reading device includes an information storage unit that stores, in an associated manner, error information on errors occurred due to a previous scan operation and operator information on an operator who produced errors, and an error analyzing unit that determines whether an error occurred due to a scan operation of a specific operator is an operator-dependent error, based on the error information and the operator information stored in the information storage unit.
