Abstract
An image forming apparatus is provided that is capable of returning from a sleep state in response to detection of a user or upon receipt of an input, wherein notification of failure to detect a user is provided if the image forming apparatus returns from a sleep state based on receipt of an input for more than a predetermined number of times.
Claims29
An image forming apparatus that operates in a first electric power state and a second electric power state where less power is consumed than in the first electric power state, the image forming apparatus comprising:
- a first detection unit configured to detect an object in a detection range;
- an operation unit configured to receive an input caused by the object being in the detection range regardless of whether the object is detected, wherein receipt of the input shifts the image forming apparatus from the second electric power state to the first electric power state;
- a control unit configured to, when the first detection unit detects the object or the operation unit receives the input, shift the image forming apparatus from the second electric power state to the first electric power state;
- and
- a notification unit configured to provide information indicating a failure condition of the first detection unit if the image forming apparatus has shifted from the second electric power state to the first electric power state as a result of the operation unit receiving the input.
An image forming apparatus that operates in a first electric power state and a second electric power state where less power is consumed than in the first electric power state, the image forming apparatus comprising:
- a first detection unit configured to detect an object present in a detection range;
- an operation unit configured to receive an input caused by the object being in the detection range regardless of whether the object is detected;
- and
- a notification unit configured to, if the first detection unit has not detected the object and the operation unit has received the input, provide information indicating a failure condition of the first detection unit.
A control method for an image forming apparatus that operates in a first electric power state and a second electric power state where less power is consumed than in the first electric power state, the control method comprising:
- shifting, if an object is detected in a detection range, the image forming apparatus from the second electric power state to the first electric power state;
- shifting, if receipt of an input, caused by the object being in the detection range regardless of whether the object is detected, is detected, the image forming apparatus from the second electric power state to the first electric power state;
- and
- providing, if the image forming apparatus shifts from the second electric power state to the first electric power state as a result of receipt of the input, information indicating a failure condition of the first detection unit.
An image forming apparatus that operates in a first electric power state and a second electric power state where less power is consumed than in the first electric power state, the image forming apparatus comprising:
- a sensor;
- an operation unit configured to receive a user operation for shifting the image forming apparatus from the second electric power state to the first electric power state;
- a control unit configured to, when the sensor detects an object in a detection range or the operation unit receives the user operation, shift the image forming apparatus from the second electric power state to the first electric power state;
- and
- a notification unit configured to notify a user of information indicating a condition of the sensor on the basis that the operation unit receives the user operation without the sensor detecting an object in the detection range.
