A CPU in the control device monitors presence/absence of power supply from the power source unit. When power is cut off during image forming, the CPU causes regenerative braking of the motors. The regenerated power is voltage-converted by a second DC-DC converter in the power source unit and supplied to the control device for continuously driving the CPU, which in turn backs up operating information. This eliminates inconsistency between the actual life status and the backed-up information when power is off, with no need of frequent backup during image forming. It is thus possible to provide the image forming device which can reliably manage operating information even if power supply to the motors is stopped during printing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming device having operating information managing function","description":"An image forming device includes a power source unit, motors supplied with and driven by electric power from the power source unit, and a control device for controlling the motors' operations.
