  • Developing apparatus
    Patent number: 4275956
    Abstract: If developer within a xerographic developing apparatus becomes excessively charged, excessive toner is added to the apparatus because the excessively charged developer prevents a sensor from sensing the actual toner density within the apparatus. To overcome this problem, an element (contacted by the developer during movement of the latter within the apparatus) is connected to ground through a surge voltage protector. This prevents both the element and the developer from being excessively charged.

  • Vibrating screen filter for toner density measuring apparatus
    Patent number: 4078520
    Abstract: If developer within a xerographic developing apparatus becomes excessively charged, excessive toner is added to the apparatus because the excessively charged developer prevents a sensor from sensing the actual toner density within the apparatus. This occurs because a screen above the sensor becomes clogged by developer and prevents developer from passing through the screen and consequently the sensor. To prevent this clogging an AC coil is connected to the screen to vibrate the latter, thus allowing developer to pass through the screen and sensor.
