  • Patent number: 9678465
    Abstract: An image forming apparatus includes a first light-emitting unit, a second light-emitting unit, and a remaining-recording-medium detector. The first light-emitting unit is arranged on an outer surface of a recording medium setting unit on which recording media are set, and emits light while the recording media are being conveyed from the recording medium setting unit. The second light-emitting unit is arranged on or near an operating member that is to be operated when a recording medium jammed in a main body of the image forming apparatus is removed. The remaining-recording-medium detector detects presence or absence of a recording medium remaining in the main body of the image forming apparatus. The second light-emitting unit emits light when the operating member needs to be operated, based on a result of detection by the remaining-recording-medium detector. The first light-emitting unit and the second light-emitting unit emit light in different manners.

  • Patent number: 9672088
    Abstract: A hardware device controller includes a controlling unit, a relay unit, and a watchdog timer. The controlling unit outputs a control signal to control a hardware device. The relay unit outputs, on the basis of the control signal, a control signal to the hardware device. When not receiving a first signal output from the controlling unit via the relay unit for a predetermined length of time or longer, the watchdog timer outputs a second signal. When the second signal is output, the controlling unit and the relay unit perform initialization process, and the hardware device stops driving.
