摘要： 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 includes an image forming unit configured to form an image on a sheet based on image data, a control unit configured to control driving of the image forming unit, and a power supply unit configured to, if a factor for shifting from a power saving state to a standby state is detected, supply power to the image forming unit and the control unit. If a first type of factor is detected as the factor in the power saving state, the power supply unit supplies power to the control unit and the image forming unit, and the control unit restricts the driving of the image forming unit. If an instruction to perform a function of forming an image on a sheet is accepted, the control unit cancels restriction of the driving of the image forming unit.

摘要： In a first power state of an image forming apparatus in which a first power supply unit supplies power to a network I/F but does not supply power to a central processing unit (CPU), if a received packet is a first type packet, a power supply control unit shifts the image forming apparatus to a second power state in which the first power supply unit supplies power to the CPU but the second power supply unit does not supply power to the image forming unit. If the received packet is a second type packet, the power supply control unit shifts the image forming apparatus to a third power state in which the first power supply unit supplies power to the CPU and the second power supply unit supplies power to the image forming unit.

摘要： An apparatus configured to operate in a first power state and in a second power state that consumes less power than the first power state. In a case where a predetermined condition is satisfied, when a power-supply-off drive for switching a switch to an off side using a drive unit is executed and if it is detected that a power supply to the apparatus is not cut after executing of the power-supply-off drive, a control unit shifts a power state of the apparatus from the first power state to the second power state.

摘要： When a job is received via a LAN and if power for a controller unit is not turned on, a LAN controller of an image forming apparatus turns on a switch and performs an operation to turn on the power for the controller unit. If the power for the controller unit is not turned on even after the operation is performed or if the main switch is turned off, the LAN controller of the image forming apparatus notifies a job sender to connect AC power supply or turn on a main switch.
