Abstract: An image forming apparatus includes an image forming device, a transport belt, an optical sensor, an ultrasonic sensor, and a controller. The transport belt transports the recording sheet. The optical sensor emits light to the transport belt, and receives the light reflected by the transport belt. The ultrasonic sensor transmits ultrasonic wave to the transport belt, and receives the ultrasonic wave transmitted through the transport belt. The controller decides whether an output from each of the optical sensor and the ultrasonic sensor represents a normal value or an abnormal value, and executes predetermined control, depending on a combination of decision results about the respective outputs from the optical sensor and the ultrasonic sensor.

Abstract: An electronic apparatus includes a drive unit having a drive roller, a driving motor, and a limited-life component, a sound collecting device that collects sound from the limited-life component, and outputs sound data, a storage device storing in advance a sound pressure level corresponding to a specific frequency of the limited-life component, with respect to each of different lengths of the remaining service life, and a controller that analyzes frequency of the sound data at predetermined time points; acquires the sound pressure level corresponding to the specific frequency of the limited-life component, on a basis of a result of the frequency analysis; compares the acquired sound pressure level with the sound pressure level of each of the lengths of the remaining service life; predicts the remaining service life of the limited-life component, on a basis of comparison result; and displays the predicted remaining service life on a display device.

Abstract: An electronic apparatus includes a drive roller, a contamination detection device that detects a degree of uncontaminatedness of a surface of the drive roller, a drive motor, a controller, and a display device. The controller executes a first feedback control, when the degree of uncontaminatedness is equal to or higher than a first threshold, executes a second feedback control including increasing the driving force to the drive motor, and displays a first screen announcing necessity to prepare for restoration of the drive roller on the display device, when the degree of uncontaminatedness is lower than the first threshold, and equal to or higher than a second threshold lower than the first threshold, and restricts the drive roller from rotating, and displays a second screen requesting restoration of the drive roller on the display device, when the degree of uncontaminatedness is lower than the second threshold.

Abstract: A heater of a sheet feeding device warms up a bundle of sheets set in a sheet cassette to dehumidify it. A first terminal makes contact with the topmost sheet. A second terminal makes contact with the bottommost sheet. When judging the necessity for dehumidification, a controller determines a judging resistance value based on the magnitude of a current passing through the bundle of sheets with a detection voltage applied to the first terminal. When the judging resistance value is equal to or lower than a threshold value, the controller operates the heater. When the determined judging resistance value is higher than a threshold value, the controller does not operate the heater.
