  • Patent number: 6206362
    Abstract: An indicator for continuously indicating the status of a media stack in a media tray is disclosed. This indicator functions independently of a media stack support in a printer. The indicator includes an indicator lever and a probe member. The indicator lever is pivotably mounted and can be tilted between two predetermined extreme positions. The probe member has a shaft which is also pivotably mounted. An engaging arm extends from the shaft. In operation, the shaft is tilted according to the status of the media stack in the media tray. As the shaft is tilted, the engaging arm engages the indicator lever, tilting the indicator lever to a position between the two extreme positions to indicate the status of the media stack.
