Provided is an image forming apparatus that reduces discomfort when returning from the energy saving mode. The image forming apparatus can switch between an energy saving mode and a normal mode that consumes more power than the energy saving mode as the operation mode. A human sensor can detect a person and calculate the distance to the person. An operation mode control unit raises the temperature of the fixing unit of the image forming unit when a person detected by the human sensor approaches within the first specific distance, and it start transport unit to be driven when the person approaches within a second specific distance, which is closer than the first specific distance.

According to an embodiment, an image processing apparatus includes a communicator, a storage, and a controller, in which the controller stores destination information received from a terminal device, via the communicator, in the storage, and erases the destination information from the storage in response to a trigger. In the image processing apparatus, the destination information is retained at least until a trigger input is made.

An image forming system includes at least one piece of image forming apparatus and a server. The at least one piece of image forming apparatus transmits a sleep notification when entering a sleep mode which is a power saving state, and transmits a wake-up notification when returning from the sleep mode to a non-power saving state. The server monitors the sleep notification and the wake-up notification. When a specific image forming apparatus of the at least one piece of image forming apparatus has been in the sleep mode for at least a certain period of time, the sever issues a power-off command to the specific image forming apparatus, so that the specific image forming apparatus shuts off automatically. Before issuing the power-off command, the server delivers a power-off notice to the user who has used the specific image forming apparatus.

An image forming apparatus includes a detection unit configured to detect an object, a reception unit configured to receive an operation of a user, and a shifting unit configured to shift, if the detection unit detects an object, a power state of the image forming apparatus from a first power state to a second power state different from the first power state, and shift, if the reception unit receives an operation of a user, the power state of the image forming apparatus from the second power state to the first power state.

An image reading apparatus executes a calibration processing of calibrating a reading unit when a medium detection sensor detects that a medium is present. The image reading apparatus executes the calibration processing each time a first time-period elapses in a state where the medium detection sensor detects that the medium is present after the calibration processing. When a start instruction of reading the medium is received, the image reading apparatus starts transport of the medium and causes the reading unit to read the medium on a basis of calibration information of a last calibration processing.

An image processing apparatus includes a print section configured to perform printing on a recording medium, a first detector configured to detect a moving object within a first detection range, a second detector configured to detect the moving object within a second detection range, and a controller configured to switch between a normal mode in which printing by the print section is enabled and a power-saving mode in which printing by the print section is disabled. The controller returns to the normal mode when, after the controller enters the power-saving mode, in response to detection of the moving object by the first detector or the second detector, the first detector or the second detector detects the moving object for a first predetermined period of time or more, and the first detector and the second detector detect the moving object for a second predetermined period of time or more.

An image reading apparatus includes a first posture detection unit that detects a first posture that is a posture of the apparatus main body when not in use, a second posture detection unit that detects a second posture that is a posture of the apparatus main body when in use, and a posture change detection unit that detects a change in a posture of the apparatus main body. When the first posture detection unit detects a switchover of the apparatus main body to the first posture in a first power supply mode in which power is supplied to the first posture detection unit, the second posture detection unit, and the posture change detection unit, the first power supply mode transitions to the second power supply mode in which a controller supplies power to only the posture change detection unit.

A machine learning system includes a sensor configured to sense an object which is present in front of an information processing apparatus, a machine learning model configured to input time-series sensed values output from the sensor and to estimate whether a user who uses the image processing apparatus is present, a user interface configured to receive an operation performed by a user, and a learning unit configured to cause the machine learning model to learn with use of training data including the time-series sensed values output from the sensor and labels that are based on presence and absence of an operation performed by a user and received by the user interface.

An information processing apparatus and method is provided and controls execution of learning processing thereon. Learning data are generated in which readings of a human presence sensor serve as input values, information on receiving or not receiving any operation from an operation panel serves as success/failure flags. The success/failure flag is generated from an assessment result of a current resumption assessment model and the information on receiving or not receiving an operation, and is provided to the learning data. Accordingly, learning processing is performed using the success/failure flags provided in the learning data, thereby efficiently implementing learning.

An information processing apparatus includes a processor configured to: receive a first time-designated operation setting to execute a first designated operation at a first designated time; and shift from a normal operation mode to a power saving mode based on an instruction, wherein the processor is configured to, if the first designated operation is not a predetermined operation, control to not return from the power saving mode to the normal operating mode to execute the first designated operation at arrival of the first designated time.
