Abstract
According to at least one embodiment, an image forming apparatus includes a first sensor, a second sensor, and a controller. The first sensor is configured to detect a user. The second sensor is configured to detect a sheet in a sheet holder. The controller is configured to change a transition mode of an operation mode based on a first detection result of the sheet in the sheet holder by the second sensor in response to the detection of the user by the first sensor when the operation mode of the image forming apparatus is a second power-saving mode, which consumes less power than a first power-saving mode.
Claims16
An image forming apparatus comprising:
- a first sensor configured to detect a user;
- a second sensor configured to detect a sheet in a sheet holder;
- and
- a controller configured to change a transition mode of an operation mode based on a first detection result of the sheet in the sheet holder by the second sensor in response to the detection of the user by the first sensor when the operation mode of the image forming apparatus is a second power-saving mode that consumes less power than a first power-saving mode,
- wherein when the operation mode is maintained in the second power-saving mode, the controller is configured to shift the operation mode from the second power-saving mode to the first power-saving mode when a predetermined number of users is detected by the first sensor, the first sensor being a single sensor,
- wherein the controller is configured to lower a detection level of the first sensor in the second power-saving mode.
A control method executed by an image forming apparatus including a first sensor configured to detect a user and a second sensor configured to detect a sheet in a sheet holder, comprising:
- changing a transition mode of an operation mode based on a first detection result of the sheet in the sheet holder by the second sensor in response to the detection of the user by the first sensor when the operation mode of the image forming apparatus is a second power-saving mode, which consumes less power than a first power-saving mode;
- wherein when the operation mode is maintained in the second power-saving mode, shifting the operation mode from the second power-saving mode to the first power-saving mode when a predetermined number of users is detected by the first sensor, the first sensor being a single sensor;
- and
- lowering a detection level of the first sensor in the second power-saving mode.
