摘要:
A technique enables appropriate establishment of tunnel communication between a gateway in a power saving mode and a cloud server, as well as a reduction in power consumption. If a management server (50) that has received from the cloud server (70) a request to access a device (10b) has no communication session with a gateway (30b) corresponding to the device (10b), the management server (50) transmits a tunnel connection request to a substitute gateway (30a) via a communication session with the substitute gateway (30a) (step S34). The substitute gateway (30a) transfers the tunnel connection request to the gateway (30b) and causes the gateway (30b) to return from the power saving mode (S39). Then, the gateway (30b) establishes tunnel communication with the cloud server (70) on the basis of the tunnel connection request (S56).

A printer includes a first CPU, a second CPU that executes processing different from processing executed by the first CPU, and a monitor target that outputs a signal indicating that a specific state has been reached to the first and second CPUs. The first and second CPUs are both configured to be capable of monitoring the signal from the monitor target. In a non-sleep state, the second CPU monitors the monitor target. In a sleep state, the first CPU monitors the monitor target.

An image processing system includes: an image processing apparatus (100); an instruction server (200) configured to transmit instruction information to the image processing apparatus (100) via a router having a firewall function; and a session server (300) configured to set up a session between the image processing apparatus and the instruction server. The image processing apparatus (100) is configured to switch, in a case where the state of the image processing apparatus is a power saving state when a time specified by a transmission interval elapses from transmission of a connection confirmation packet for the session with the instruction server (200), to a state in which at least the connection confirmation packet can be transmitted.
摘要:
An image forming apparatus or the like is provided, which can make a user recognize a position which the user should operate in order to manually return the image forming apparatus from a power conservation state to a normal power state, even in the case where the image forming apparatus does not automatically return, using a human-body detection sensor, from the power conservation state to the normal power state. An image forming apparatus that enters a first power state in which a predetermined function is executable and a second power state in which the predetermined function is not executable includes detection means for detecting an object in the vicinity of the image forming apparatus; an operation section that a user operates in order to shift the image forming apparatus from the second power state to the first power state; notification means for, in a case where an object has been detected by the detection means, providing a notification of information indicating a position of the operation section; and power-source control means for, in a case where the operation section has been operated by the user, shifting the image forming apparatus from the second power state to the first power state.

An information processing apparatus which is capable of, when hang-up occurs, eliminating the hang-up state and restoring to a normal state without bothering a user. A first power supply unit supplies power to predetermined devices among a plurality of devices, and a second power supply unit supplies power to the plurality of devices. When startup is done with power being supplied to the predetermined devices, software is started by supplying power to all of the plurality of devices. When the second power supply unit is turned on during the startup, whether or not the software has been normally started is determined. When the software has not been normally started, the software is restarted by carrying out an off-on process in which the plurality of devices are reset, the second power supply unit is turned off, and then the second power supply unit is turned on again.
摘要:
An image forming apparatus operates in a first power state, a second power state returnable to the first power state by a return instruction, or a third power state power-saved as compared with the second power state. The image forming apparatus comprises: a controlling unit to transition the power state of the image forming apparatus to the first power state, the second power state or the third power state; and a power-supply switch to cut off power supply to the image forming apparatus by being turned off by an internal mechanical relay driven by a manual operation or controlling from the controlling unit, wherein the controlling unit controls to turn off the power-supply switch after transitioning the power state from the second power state to the third power state.
摘要:
An image forming system includes an image forming apparatus (100a) and a host apparatus (200). The image forming apparatus (100a) counts an idle state time during which the image forming apparatus is not in use, and,when the idle state time reaches a predetermined threshold time, transmits a notice screen display command to the host apparatus. The host apparatus (200) displays a notice screen, and, when a turn on time extension menu is selected on the notice screen, transmits a turn on time extension command to the image forming apparatus. When the turn on time extension command is received, the image forming apparatus resets a timer unit (140) and recounts the idle state time, and, when the turn on time extension command is not received for a predetermined time, is automatically turned off.
