Abstract: An image forming apparatus capable of transitioning between at least a standby state and a termination state, the image forming apparatus including a controller and a printer device configured to form an image on a recording sheet. The controller is configured to receive an event for transitioning a state of the image forming apparatus, and the controller is configured to, by executing a termination process of the printer device and a termination process of the controller, transition from the standby state to the termination state. When a reboot event is received by the controller, the controller controls to execute a termination process of the controller without executing a termination process of the printer device.

The image forming apparatus includes a display control unit configured to control a display on an operation unit, a reception unit configured to receive an end notification for end processing of the image forming apparatus, and a processing unit configured to perform, in response to receipt of the end notification by the reception unit, the end processing of the image forming apparatus, wherein, in response to receipt of the end notification by the reception unit when the image forming apparatus is in the second power state in which the operation unit is turned off, the display control unit turns on the operation unit.

Abstract: An information processing apparatus for making state transition between a plurality of power states including a suspend state includes one or more controllers having one or more processors and one or more memories. The one or more controllers is configured to function as a control unit configured to, in a case where a state transition to the suspend state fails, inhibit the state transition to the suspend state and then perform a shutdown.

Abstract: Upon receiving a resumption notification from a system controller, a printer driver determines whether a power supply to a printer apparatus has stopped/resumed after a previous transition instruction to a sleep state was transmitted to the printer apparatus. If stop/resumption is not performed, an initialization negotiation processing performed to the printer apparatus when stop/resumption is not performed.

Abstract: A device of a lower hierarchy in a power supply configuration sets a flag of a non-volatile storage area when the device of the lower hierarchy reset by WDT. In a case where the flag at the time of starting, the device of an upper hierarchy is notified that the device of the lower hierarchy in the power supply configuration is reset. Thus, the device of the upper hierarchy initializes the entire system, and the image forming apparatus can be operated.

Abstract: Upon receiving a resumption notification from a system controller, a printer driver determines whether a power supply to a printer apparatus has stopped/resumed after a previous transition instruction to a sleep state was transmitted to the printer apparatus. If stop/resumption is not performed, an initialization negotiation processing performed to the printer apparatus when stop/resumption is not performed.

Abstract: An apparatus includes a control unit configured to switch a power state among a first power state, a second power state, and a third power state, the first power state being a state where a device driver is loaded and a device is usable, the second power state being a state where the device driver is unloaded and the device is unusable, the third power state being a state where the device driver is unloaded and the device is unusable, power consumption in the third power state being less than power consumption in the second power state. Based on reception of a predetermined signal in a case where the information processing apparatus is in the third power state, the control unit causes the power state to transition from the third power state to the second power state.

Abstract: When a power state of an image forming apparatus is switched to a sleep state based on occurrence of an event, during a predetermined period after the occurrence of the event, the image forming apparatus does not return from the sleep state in a case where a return-from-sleep event corresponding to pressing a touch panel or pressing a key occurs, and returns from the sleep state in a case where a return-from-sleep event corresponding to an event other than pressing the touch panel and pressing the key occurs.

Abstract: An apparatus includes a control unit that switches a power state between first and second power states, the first power state being a state where one of a plurality of cores is usable and the other cores are unusable, the second power state being a state where the plurality of cores is unusable. Based on reception of the predetermined signal in a case where the apparatus is in the second power state, the control unit causes the apparatus to transition from the second power state to the first power state, and under a first condition to be met after the transition to the first power state in a case where the apparatus is in the first power state, the control unit causes the apparatus to transition from the first power state to the second power state.

Abstract: A device of a lower hierarchy in a power supply configuration sets a flag of a non-volatile storage area when the device of the lower hierarchy reset by WDT. In a case where the flag at the time of starting, the device of an upper hierarchy is notified that the device of the lower hierarchy in the power supply configuration is reset. Thus, the device of the upper hierarchy initializes the entire system, and the image forming apparatus can be operated.

Abstract: An information processing apparatus includes an adjustment unit configured to adjust a write condition to reduce a capacity of data to be written to a first storage unit before starting predetermined processing including processing for writing data to the first storage, the write condition being a condition for writing data to the first storage unit, and a restoration unit configured to restore the write condition to an original condition set before the write condition is adjusted by the adjustment unit, after completion of the predetermined processing.

Abstract: A communication system including a first communication apparatus having an image forming unit for forming an image on a sheet and a first wireless communication unit for performing wireless communication, and a second communication apparatus having a second wireless communication unit for performing wireless communication and a reading unit for reading an image. The first communication apparatus registers first network information and prints a QR code based on second network information. The second communication apparatus reads the QR code-printed sheet to acquire the second network information, requests the first communication apparatus to establish direct wireless communication based on the second network information, acquires the first network information from the first communication apparatus using the direct wireless communication, and connects to a router based on the first network information to start wireless LAN communication.

According to a second interrupt signal output from the second WDT circuit based on expiration of the extended second timer time, execution of a process for resetting the system is controlled.

Abstract: In an image forming apparatus to which a finisher is connected, a power source control unit shifts the image forming apparatus to a power saving state. The image forming apparatus is inhibited from being shifted to the power saving state when it is detected that a sheet for which a binding process is to be performed is set in the finisher. The image forming apparatus may be permitted to be shifted to the power saving state when it is not detected that the sheet is set in the finisher.
