Abstract
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.
Claims13
A printing apparatus comprising:
- a first detection unit configured to detect a human;
- an operation unit configured to be operated by an operator;
- a print unit configured to print an image on a sheet by execution of a print job;
- and
- a second detection unit configured to detect whether the operation unit has been operated,
- wherein power consumption of the printing apparatus increases based on the first detection unit detecting the human, and
- wherein, after the power consumption of the printing apparatus increases, in a case where a human is not detected by the first detection unit and a first operation is executed by the print unit, the power consumption of the printing apparatus decreases before a lapse of a preset time, and in a case where a human is not detected by the first detection unit and a second operation is executed by the operation unit, the power consumption of the printing apparatus decreases when the preset time lapses.
