Image forming apparatus, control method of image forming apparatus, and program
An image forming apparatus includes: an accepting unit to accept user operations to transition the apparatus from a standby state to a power save state; a detecting unit to detect objects around the apparatus; and a power control unit to transition the apparatus from the power save state to the standby state according to detection of an object by the detecting unit, and to transition the image forming apparatus from the standby state to the power save state according to user operations accepted at the accepting unit. The power control unit prohibits the apparatus from transitioning from the power save state to the standby state according to the detection of the object, until a user, which performed operations accepted by the accepting unit to transition the apparatus from the standby state to the power save state, thereafter ceases to be detected by the detecting unit.
1. An image forming apparatus, having a power state including at least a standby state, and a power save state which consumes less power than the standby state, the image forming apparatus comprising:
an accepting unit configured to accept user operations from a user to transition the power state from the standby state to the power save state;
a detecting unit configured to detect objects including the user; and
a power control unit configured to transition the power state from the power save state to the standby state in accordance with detection of an object by the detecting unit, and to transition the power state from the standby state to the power save state in accordance with the accepted user operations;
wherein the power control unit prohibits the power state from transitioning from the power save state to the standby state in accordance with detection of an object by the detecting unit, while the user, which has performed the accepted user operations, is detected by the detecting unit.
2. The image forming apparatus according to claim 1 ,
wherein the detecting unit is a sensor array where sensors receiving infrared light are arrayed in a matrix form.
3. The image forming apparatus according to claim 1 , wherein the detecting unit includes
a first detecting unit, and
a second detecting unit having a narrower detecting range than that of the first detecting unit.
4. The image forming apparatus according to claim 3 ,
wherein, in a case of the first detecting unit detecting an object, the second detecting unit is enabled to detect objects; and
wherein the power control unit transitions the image forming apparatus from the power save state to the standby state in a case where the second detecting unit regarding which detection has been enabled has detected an object.
5. The image forming apparatus according to claim 1 , wherein in a case where there is no job after having transitioned to the normal power mode, the power control unit prohibits the image forming apparatus from transitioning from the power save state to the standby state in accordance with detection of an object by the detecting unit, while the user, which has performed the accepted user operations, is detected by the detecting unit.
6. The image forming apparatus according to claim 1 , wherein the power control unit
transitions the power state from the power save state to the standby state in accordance with detection of an object other than the user by the detection unit.
7. The image forming apparatus according to claim 1 , further comprising:
a storage unit configured to store information in a case where the accepting unit accepts the user operation, the information being deleted in a case where the user ceases to be detected by the detection unit;
wherein the power control unit prohibits the power state from transitioning from the power save state to the standby state in accordance with detection of an object by the detection unit in a case where the storage unit stores the information.
8. The image forming apparatus according to claim 1 , further comprising:
a printing unit configured to print an image on a sheet based on image data.
9. A control method of an image forming apparatus, having a power state including at least a standby state, and a power save state which consumes less power than the standby state, the method comprising:
accepting user operations from a user to transition the power state from the standby state to the power save state by an accepting unit;
detecting objects including the user by a detecting unit; and
transitioning the power state from the power save state to the standby state in accordance with detection of an object;
transitioning the power state from the standby state to the power save state in accordance with the accepted user operations; and
prohibiting the power state from transitioning from the power save state to the standby state in accordance with detection of an object, while the user, which has performed the accepted user operations, is detected by the detecting unit.
10. A non-transitory recording medium storing a program causing a computer of an image forming apparatus, having a power state including at least a standby state, and a power save state which consumes less power than the standby state, to perform operations, the operations comprising:
accepting user operations from a user to transition the power state from the standby state to the power save state;
detecting objects including the user;
transitioning the power state from the power save state to the standby state in accordance with detection of an object by the detecting unit, and transitioning the power state from the standby state to the power save state in accordance with the accepted user operations; and
prohibiting the power state from transitioning from the power save state to the standby state in accordance with detection of an object by the detecting unit, while the user, which has performed the accepted user operations, is detected by the detecting unit.
