Latest Patents

One of Schaefer's key patents is titled "Toner container having a magnet for toner level sensing." This invention features a toner container designed for use in image forming devices. The container includes a housing with a reservoir for storing toner, a paddle positioned within the reservoir, and a rotatable drive member that pushes the paddle in a first rotational direction. The paddle is free to rotate ahead of the drive member, allowing for improved toner level sensing. A magnet is rotatably coupled to either the paddle or the drive member, while a shield is also rotatably coupled to the other component. This design enables the shield to move between a blocking position and an unblocking position, effectively managing the detection of the magnetic field by a sensor based on the paddle's rotational position.
