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.

Method and device for setting the toner concentration in the developer station of an electrophotographic printer or copier

A method and device controls a printer or copier to generate a plurality of marks that are assembled into a coherent marking band that is then inked by the toner. A sensor measures the marking band. The printer or copier are controlled based on the output of the sensor.

Method for controlling a printer or copier using a toner mark band and reflex sensor working according to the triangulation principle

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.

Apparatus and method for acquiring the nature of a toner particle layer and the moisture content of a carrier material in a printer or copier

A printer or copier includes a high speed monochrome or two color printer portion and a slower full color printer portion. Print job signals are divided into monochrome and color printed pages and sent to the corresponding printer portion. The printers, or a paper handling path between the printers, is controlled to assemble the printed pages into a predetermined sequence order.
