Latest Patents
One of Nakajima's latest patents is an image forming apparatus configured to determine the abnormality of a drum unit earth terminal. This innovative apparatus includes a drum unit, a charging roller, a detector, a controller, a developing unit, and a notification unit. The detector plays a crucial role by detecting the amplitude of a first alternating-current voltage output to the charging roller. The controller ensures that the amplitude deviation between the first alternating-current voltage amplitude and the output target value is minimized. The developing unit is responsible for developing an electrostatic latent image on the drum unit based on a second alternating-current voltage. Additionally, the notification unit alerts users to any abnormalities in the earth terminal based on amplitude deviations in different states.
Another notable patent is for a power supply apparatus and image forming apparatus designed to determine malfunction or load abnormality. This power supply apparatus generates a bias voltage and outputs it to a load. It includes a power supply circuit that outputs a determination signal and a detection current signal. The controller manages the generation of the bias voltage and determines any malfunctions or abnormalities based on the signals received.
