Disclosed is an image forming apparatus including at least one processor configured not to shut down the image forming apparatus when a reply not permitting shutdown of the image forming apparatus is included in replies from remote operation devices other than the remote operation device that has transmitted a shutdown instruction among a plurality of the remote operation devices.

Image forming apparatus communicable with plural remote operation devices, at least one of which is able to shut down the image forming apparatus

An image forming apparatus capable of switching power state between a first power state and a second power state, which is lower in power than the first power state, shifts from the second power state to the first power state. In a case where the image forming apparatus shifts to the second power state in response to a current time reaching a set time, the image forming apparatus is controlled not to shift from the second power state to the first power state in response to an object approaching the image forming apparatus being detected.

Image forming apparatus, method for controlling image forming apparatus, and recording medium

An image forming apparatus includes a detection unit configured to detect an object and a power-supply control unit. The power-supply control unit shifts the image forming apparatus to a second power state, in response to a lapse of a predetermined time following no detection of the object, when a job has not been executed until the detection unit detects no object, after the power-supply control unit shifts the image forming apparatus to the first power state. The power-supply control unit shifts the image forming apparatus to the second power state before a lapse of the predetermined time, when a job has been executed until the detection unit detects no object, after the power-supply control unit shifts the image forming apparatus to the first power state.

Image forming apparatus, method for controlling image forming apparatus, and storage medium

The present disclosure is directed to switch a voltage to be supplied to a power source switch in accordance with a state of a power source of an apparatus and restrain power consumption of the power source switch.

Information processing apparatus, controlling method thereof, and program

An information processing apparatus includes a power controller configured to perform one of first control, which, in response to the information processing apparatus transitioning from a second power state to a first power state, supplies electric power to a storage device and drives a spindle motor, and second control, which, in response to the information processing apparatus transitioning from the second power state to the first power state, supplies electric power to the storage device without driving the spindle motor, wherein, when the information processing apparatus is in the second power state, the power controller performs the first control based on a state controller receiving a first request signal, and the power controller performs the second control based on the state controller receiving a second request signal different from the first request signal.

Information processing apparatus and control method for information processing apparatus for transitioning from one power state to another power state

Image forming apparatus with power control based on human detection, method for controlling image forming apparatus, and recording medium

A power supply apparatus of the present invention has a power factor correction circuit that corrects a power factor; a voltage converter connected to a secondary side of the power factor correction circuit; a power control unit that outputs a first signal for turning the power factor correction circuit on, and outputs a second signal for turning the voltage converter on; and a signal output unit that, in accordance with having being inputted with the first signal and the second signal, outputs a signal for turning the voltage converter on.

Power supply apparatus and method of controlling power supply apparatus

An information processing apparatus including a push switch turns off a power supply state of a main body and starts shutdown processing when a first user's operation is performed on the push switch in a normal state of the apparatus. When a second user's operation is performed on the push switch during the shutdown processing, the power supply state of the main body is switched between on and off. If the power supply state of the main body is the on state when the shutdown processing is completed, first processing for restarting the main body is performed, and if the power supply state of the main body is the off state when the shutdown processing is completed, second processing for stopping power supply to the main body is performed.

Information processing apparatus including push switch, power supply control method therefor, and storage medium

An information processing apparatus capable of notifying a user of a state of data transmission via short-range wireless communication. An NFC tag controller of an MFP as an information processing apparatus holds communication setting information for wireless LAN communication, and transmits the communication setting information to a mobile terminal as an external apparatus, via NFC communication by dividing the information. An interrupt signal generated by the NFC tag controller for notifying completion of transmission of a divided information item to the mobile terminal is detected, and when the number of times of detection of the interrupt signal reaches a predetermined number of times, the user is notified that the transmission of the communication setting information is completed.

Information processing apparatus that performs short-range wireless communication, method of controlling the same, and storage medium

An image forming apparatus capable of shifting to a state where quick activation thereof can be performed in a shorter time period when a power switch is turned off. When the off operation of the power switch is detected, a first state is stored, and when the on operation of the power switch is detected next, the state of the image forming apparatus is shifted to a second state from which the image forming apparatus can return to the first state. When the state of the image forming apparatus is shifted to the second state, time starts to be measured. When the on operation of the power switch is detected in the second state, the value of the measured time is acquired. The image forming apparatus is caused to return to the stored first state depending on the value of the measured time.

Image forming apparatus that shifts to state where quick activation is possible, method of controlling the same, and storage medium

An image processing apparatus that is capable of being instructed to power off, by a power switch or a command from an external apparatus, and is capable of executing the restart thereof under appropriate conditions. When power-off is instructed, shutdown is started. Upon completion of the shutdown, if the power switch is on, and at the same time the power-off has been instructed by the power switch of the apparatus, the restart of the apparatus is executed, whereas upon completion of the shutdown, if the power-off has been instructed by a command from the external apparatus, the restart of the apparatus is not executed.
