An ink heating device () includes a heater circuit () including a heater () which heats ink and an auto-return type bimetal switch () which is provided between the heater () and a power source (A); a relay () provided between the bimetal switch () and the power source (A); and a controller () which opens or closes the relay () according to a state of the heater circuit ().

Ink heating device, ink supply device and image forming system

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.

Image forming apparatus that detects status of transport belt that transports recording medium

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.
