  • Capacitive toner level sensor
    Patent number: 9395645
    Abstract: A toner container including a first electrode disposed within the toner container, a second electrode electrically connected to the first electrode and disposed within the toner container, and a sense electrode disposed between the first electrode and the second electrode. The sense electrode and the first electrode form a first capacitor having a first capacitance that changes in response to a change in toner amount existing therebetween. The sense electrode and the second electrode form a second capacitor having a second capacitance that changes in response to a change in toner amount existing therebetween.
    Type: Grant
    Filed: April 7, 2014
    Date of Patent: July 19, 2016
    Assignee: Lexmark International, Inc.
