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.
