Abstract: Some examples include a media level state indicator of an image forming apparatus. The media level state indicator including a gear assembly of interconnected gears including a first gear, a second gear, and a cam fixedly disposed on the first gear, the second gear coupled to a media lift system and rotatable with a shaft of the media lift system, the first gear and the cam rotatably coupled to the second gear, a cam follower to selectively contact the cam, the cam follower moveable in response to contacting rotational movement of the cam, and a signal device coupled to the cam follower, the signal device having a first media level state and a second media level state, the signal device to move between the first media level state and the second media level state as the media lift system changes a position of a lift plate.

Abstract: In an example, an apparatus is described that includes a non-resistive heat source, a thermally conductive face, and a temperature detector. The thermally conductive face has a controlled long-wave infrared emissivity and is in thermal contact with the non-resistive heat source. The temperature detector is positioned to detect a temperature of the thermally conductive face.

Abstract: In some examples, a controller is to receive a measurement from a sensor in an enclosure, and use the measurement and a baseline value to represent a condition of an airflow flowing through a filter that removes particulates from an incoming airflow into the enclosure. Based on the measurement and the baseline value, the controller is to selectively adjust a setting of an airflow generator that causes the incoming airflow through an inlet into the enclosure, or indicate that the filter is to be replaced.
