  • Patent number: 10895838
    Abstract: An image forming apparatus includes a mounting unit to which a developer container is mounted, a controller to control a motor to rotate the mounted container, and a sensor to detect a predetermined portion in which the mounted container is rotated. The controller determines whether the container is mounted based on the detection result of the sensor, wherein the controller controls the motor based on the detection result so that a rotation speed of the mounted container is equal to a predetermined rotation speed. After a door is opened, in a case where, while communication between a communication unit and a memory is maintained, a detection result of the sensor is changed from a first detection result in which the predetermined portion is detected to a second detection result in which the predetermined portion is not detected, the controller determines the mounted container has been manually rotated.

  • Patent number: 10837409
    Abstract: A purge system malfunction diagnosis device is configured to diagnose a malfunction in a purge system mounted on a vehicle. The purge system includes a canister, a purge passage, a purge valve capable of opening and closing the purge passage, an outside air passage configured to cause the canister to communicate with an outside air opening, an outside air valve capable of opening and closing the outside air passage, and a system pressure sensor configured to detect a pressure in the purge system. In a state where the outside air passage is closed, a diagnosis mode is executed on a basis of a relationship between the pressure in the purge system and an integrated value of flow rate estimates of a purge gas. In the diagnosis mode, a parameter to be used for diagnosing a malfunction in the purge system is adjusted in a case where the flow rate estimate is lower than a flow rate threshold.
