  • Patent number: 7433613
    Abstract: In a method and system for setting toner concentration of a toner particle-carrier particle mixture in a developer station for development of a latent charge image on a carrier, a sensor is arranged in the developer station measuring the toner concentration. Toner feed in the developer station is adjusted. A current consumption value is determined for toner particles. From the toner concentration measured with the sensor and from the toner consumption value, a toner concentration is calculated at a location in the developer station at which the toner is extracted. A calculated toner concentration at the toner extraction location is input as a control variable used to adjust toner feed so that the calculated toner concentration approaches a desired value.

  • Publication number: 20060099000
    Abstract: In a method or apparatus for control of a point in time of a measurement of toner concentration in a developer mixture comprising toner and carrier, and wherein the developer mixture is mixed by a bucket roller provided with buckets, a toner concentration sensor is arranged for measurement of the toner concentration. Magnet bars are provided on the buckets, which magnet bars are interrupted in a region of the toner concentration sensor except for one of the magnet bars which is uninterrupted. The toner concentration sensor emits a sensor signal that exhibits a first pulse-shaped spike upon passage of the uninterrupted magnet bar and which has a larger amplitude compared to further pulse-spikes of smaller amplitude upon passage of the interrupted magnet bars. The sensor signal indicates the toner concentration between the pulse-shaped spikes.

  • Patent number: 6771913
    Abstract: An apparatus and method are provided for acquiring the nature of a toner particle layer in a printer or copier. An apparatus and a method are also provided for acquiring the moisture content of a carrier material in a printer or copier. A toner particle layer is transported forward between two capacitor plates arranged next to one another and a cooperating electrode. In a first switch status, the first and the second capacitor plate are charged with voltages opposite one another. In a second switch status, the first and the second capacitor plate are electrically connected to one another, whereby the remaining charge is identified and conclusions about the nature of the toner layer are drawn therefrom.

  • Patent number: 6286925
    Abstract: The printhead has a multitude of adjacently arranged channels with piezo-electrical shear converters. The impulse form for activation of the converters—depending upon the number of simultaneously activated neighboring channels—is changed in such manner that the exit velocity of the ink droplets is constant. This makes it possible to obtain a better print image.
