  • Patent number: 11841665
    Abstract: An image forming apparatus includes a connector, a conveyance unit, and a controller. The conveyance unit includes first and second sensors, first and second light sources, and a capacitor. Based on the first and second sensors, the controller determines a position of a paper jam having occurred during an image formation job. The first light source is turned-on when the position of the paper jam corresponds to a position of the first sensor and the second light source is turned-on when the position of the paper jam corresponds to a position of the second sensor. When the conveyance unit is pulled out of the image forming apparatus, the connector shuts off the electrical connection between the conveyance unit and a power source, and a light source controlled to turn on by the controller glows based on electric power accumulated in the capacitor during the image formation job.
