Abstract
A printing machine with an electrophotographic device, having a photoconductor, a photoconductor drive and an illumination device. The electrophotographic unit can be provided with the substrate by a feed device. The photoconductor drive motor is adjusted by a controller and the feed device can be linearly adjusted by a feed device drive motor. In order to produce high-definition prints, especially images or lettering on plate-shaped substrates, the feed device drive motor is adjusted by a controller that is controlled by a master-slave controller via a setpoint feed. The controller for the photoconductor drive motor is also controlled by the master-slave controller via a setpoint feed and the master slave controller synchronizes the feeding speed of the feed device and the speed of movement of the photoconductor.
