Abstract: In a device or method to change a belt in a machine assembly, a gripper is provided with two flat legs. The legs are held at one end and are free at the other ends. The legs are provided with a respective protective film on side surfaces facing towards one another to protect the belt. A first of the two legs facing towards the machine assembly in an exchange of the belt have a sliding film on its outer surface. The legs are designed such that they exert a gripping force over a width of the belt after sliding onto the belt and grip the belt so that the belt can be slid onto or removed from rollers of at least one of the roller types selected from the group consisting of a drive roller and a deflection roller provided in the machine assembly.

Abstract: In a method or system for controlling a printer or copier, a separation of a position mark printed on a web-shaped carrier material in a longitudinal direction of the carrier material relative to a transverse fold present in the carrier material is preset as a parameter. Arrival of the position mark is monitored with a sensor arrangement arranged before a transfer printing area while the carrier material is moved past the sensor arrangement. A real position of the transverse fold is determined for a position of arrival of the position mark at the sensor arrangement. The transverse fold is conveyed to a desired position by consideration of the real position of the transverse fold.

Abstract: In a method for electrographic printing of color images on a final image carrier, charge images of images to be printed are generated on a charge image carrier and are developed into toner images with toner, the toner images being transferred onto an intermediate carrier from which they are transfer-printed onto the final image carrier. The charge images for individual colors of the color image are generated in succession on the charge image carrier and are developed into individual color toner images with color toner. The individual color toner images are transferred onto the intermediate carrier and are there collected atop of one another in a color collection cycle to form a complete color toner image. Before transfer printing of the complete color toner image on the final image carrier, the final image carrier is pivoted onto the intermediate carrier, and after the transfer printing, the final image carrier is pivoted away from the intermediate carrier.

Abstract: In a method and a system for generation of print images on a carrier material, an actual speed difference is generated in a transfer printing region between an image carrier and the carrier material. A deviation of the actual speed difference from a desired speed difference is determined with aid of a measurement arrangement.

Abstract: A device and a method for controlling a position of a lateral edge of a continuous web of a recording medium in a printer or copier provides that sensors are provided. Signals of the sensors are supplied to a control device which includes an actuator. The actuator changes the position of the lateral edge of the web.

Abstract: The invention relates to a method and an arrangement for generating positionally-accurate print images on a carrier material with the aid of an electrophotographic printer or copier. A positioning error of the position of the carrier material with respect to a toner image present on the toner image carrier is determined, which error occurs during the contacting of a carrier material to be printed. Dependent on the positioning error determined, for every subsequent contacting of the carrier material to be printed with the toner image carrier, the position of the carrier material with respect to the toner image is adapted before the contacting such that the carrier material and the toner image are arranged with respect to one another substantially free of positioning errors.

Abstract: 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.

Each sensor outputs a sensor signal dependent on a position of the actuating element, the position of the actuating element with respect to the sensors changing dependent on a position of the unit. In a first position of the unit, the actuating element is positioned such that the first sensor and the second sensor each output a first sensor signal. In a second position of the unit the actuating element is positioned such that the first sensor outputs a second sensor signal and the second sensor outputs the first sensor signal. In a third position of the unit the actuating element is positioned such that the first sensor and the second sensor each output the second sensor signal.

Abstract: In a method and device to control a print process in a printer or copier, with a character generator generating a latent print image and a latent toner marking on an image carrier. An exposure energy per unit area for the generation of the latent toner marking is decreased in comparison to an energy per unit area for generation of the latent print image. The latent print image and the latent toner marking are developed with toner in the developer station. An optical reflection sensor determines color density of the developed toner marking. Toner concentration is adjusted in a developer station dependent on a signal of the reflection sensor.
