Abstract
When an image forming apparatus satisfies a condition to shift it to a power saving state, if a specific function that needs to respond to an inquiry from an external apparatus within a predetermined time is set, a power control unit shifts the image forming apparatus to a first power saving state in which power is supplied to a control unit configured to respond to the inquiry, and if the specific function is not set, shifts the image forming apparatus to a second power saving state in which no power is supplied to the control unit.
Claims23
An image forming apparatus comprising:
- a printer unit configured to print an image on a sheet or a scanner unit configured to scan an original;
- a storage which stores a setting of a specific function regarding network transmission or reception;
- a network controller which receives a request via a network from an external device and transmits a response to the request via the network to the external device;
- a processor which processes data received by the network controller;
- and
- a power controller which shifts the image forming apparatus from a predetermined power state to a first power saving state in which power consumption is lower than power consumption in the predetermined power state and power is supplied to the processor and the network controller or shifts the image forming apparatus from the predetermined power state to a second power saving state in which power consumption is lower than power consumption in the predetermined power state and no power is supplied to the processor and power is supplied to the network controller,
- wherein the power controller determines the first power saving state or the second power saving state as a power saving state to be shifted based on the setting of the specific function stored in the storage, and the power controller shifts the image forming apparatus from the predetermined power state to the determined power saving state when a predetermined condition is satisfied.
